How does the temperature affect the microscale adhesion behavior of different types of plastics, rubber, and composites?
Best insight from top research papers
Temperature plays a crucial role in influencing the adhesion behavior of various materials at the microscale. Research indicates that for polymers like polydimethylsiloxane (PDMS), perfluoropolyether dimethacrylate (PFPEdma), and polyurethane (PU-ht), adhesion properties can vary significantly with temperature. Specifically, the glass transition temperature (Tg) is a critical parameter affecting adhesion performance, with PU showing the highest pull-off stresses at 60°C. Additionally, in thermoplastic welding processes, such as fusion bonding, temperature is a key factor impacting the mechanical quality of adhesion between composite parts. Furthermore, studies on rubber adhesion reveal that cooling below the glass transition temperature can lead to a substantial increase in pull-off force due to the "frozen-in" elastic deformation energy. Overall, temperature plays a vital role in modulating the adhesion behavior of plastics, rubber, and composites at the microscale.

Effect of contact angle of polymer film on adhesive strength?4 answersThe contact angle of a polymer film plays a crucial role in determining its adhesive strength. Research indicates that the contact angle, along with interfacial adhesion, significantly influences the adhesion between materials. Understanding the surface free energy of a polymer through contact angle measurements helps predict its adhesion potential. Experimental results demonstrate that the adhesive strength in adhesion joints is affected by the contact geometry, with optimal joint angles maximizing adhesion. Moreover, studies on polymeric composites show that increasing the contact angle by adjusting the weight ratio of additive cement enhances adhesion strength, making the coating water-impermeable. Therefore, controlling the contact angle of polymer films is essential for achieving strong adhesive bonds in various applications.
How does temperature affect the friction coefficient?5 answersThe friction coefficient is influenced by temperature in various ways. In the process of gear meshing, the friction coefficient of the gear tooth surface is indirectly affected by temperature through its impact on gear material parameters. For the Fe-PTFE friction process, an increase in temperature leads to a decrease in the friction coefficient due to reduced interaction forces among PTFE beads. Similarly, the static friction coefficient between internal assembly contact surfaces changes with temperature, affecting the accuracy and stability of precision instruments. In the case of the cylinder-liner piston ring (CL-PR) friction pair, the friction coefficient shows different trends with temperature for different lubricating oils, with some oils experiencing a decrease followed by an increase, while others show an increase followed by stability. In the field of earth sciences, the coefficient of friction between solid and gouge is influenced by temperature, pore pressure, and pressure, with the possibility of a change in frictional resistance from stick slip to stable sliding under supercritical water conditions.
What is the importance of the factors of adhesion in microbiology?4 answersFactors of adhesion play a crucial role in microbiology. These factors are expressed in microorganisms that can form biofilms, contributing to the severity of intrahospital infections. Adhesion is important for the initial stages of biofilm formation, but it also has implications within biofilm communities. Adhesion allows cells to remain in a biofilm, but highly adhesive cells may face immobility and potential burial at the base of the biofilm. However, adhesion can also enable cells to capture substratum territory and outcompete less adhesive cells, particularly on host epithelial surfaces. Understanding the specific influences of factors such as roughness, stiffness, topography, and chemical composition on bacterial adhesion can guide efforts to prevent biofilm formation. Additionally, studying microbial adhesion is important for determining the virulence of bacteria and its impact on the development of pathology, aiding in laboratory diagnostics of infectious diseases.
What polymers or polymer composites withstand the highest temperature?4 answersHigh-temperature polymers and polymer composites that can withstand high temperatures have been extensively studied. Aromatic polyamides, aromatic polycarbonates, aromatic polyethers, phenylene-containing polymers, poly(ether ether ketone), polybenzimidazoles, polybismaleimides, polybenzoxazines, and polysulfones are some examples of high-temperature polymers. These polymers possess superior thermal stability due to the presence of aromatic rings in their structure. In addition, polymer composites with high dielectric constants and temperature stability have also been developed. For example, a polymer composite with interconnected BaTiO3 ceramic scaffold exhibits a high dielectric constant of ≈210 at a low volume fraction of ≈18 vol%. Another composite, composed of polyimide blended with high-insulation magnesium oxide nanosheets, shows high breakdown strength and low dielectric loss, with an ultra-high capacitance performance at 150 °C. These high-temperature polymers and polymer composites have potential applications in flexible electronics, high-power electronic devices, and aerospace applications.
What is the mechanism of adhesion of polyurethane in metals?2 answersThe mechanism of adhesion of polyurethane in metals involves both physical and chemical processes. When polyurethane monomers are exposed to metal surfaces, they form adsorbate layers that contain water originating from the metal surfaces. These adsorbate layers undergo changes over time, with the formation of urea-like species that are easily removed by a rinsing process. However, the remaining isocyanate molecules strongly and specifically adhere to the metal substrates, indicating a chemical adhesion mechanism. The strength of adhesion is influenced by factors such as the amount of isocyanate present, adhesion temperature, and time. Excessive temperature and time can lead to a decrease in adhesion strength due to the decrease in solvent content and thermal degradation of the adhesive. Overall, the adhesion mechanism of polyurethane in metals involves the formation of chemical bonds between the isocyanate molecules and the metal surfaces.
How do plastic components respond to different temperatures?4 answersPlastic components respond to different temperatures by undergoing various types of strain and deformation. When subjected to high temperatures and thermal gradients, plastic components experience reversible elastic and thermal strains, as well as irreversible plastic and viscoelastic (creep) strains. These strains depend on the stress and temperature levels and can be described using the theory of non-isothermal plastic deformation of elastic strain-hardening solids. At low temperatures, some materials exhibit discontinuous plastic flow, characterized by serrated yielding and the accumulation and release of dislocations. The response of stress in these materials is defined in terms of stages within each serration cycle, with temperature playing a role in the strain rate sensitivity. Plastic components can also be affected by extreme temperatures, such as those found between a storm door and a door exposed to direct sunlight. In these cases, a stabilizing layer is used to hold the core material in place and prevent distortion and shrinkage.
