What is literatures saying on CNTs-Polymer mechanical properties foe prosthethics?
10 answers
The literature on carbon nanotubes (CNTs) reinforced polymer composites for prosthetics highlights their significant potential due to the exceptional mechanical properties of CNTs, including high tensile strength, Young's modulus, and low density, which make them ideal for enhancing the mechanical performance of polymer composites used in prosthetic applications. Specifically, the integration of CNTs into polymers has been shown to improve the stiffness-to-weight and strength-to-weight ratios, crucial for developing advanced prosthetic devices that require high strength and modulus while maintaining lightweight for user comfort. For soft prosthetics, the use of a carbon nanotube-elastomer compound material has been explored as an actuator, leveraging the unique properties of CNTs to overcome limitations such as the high applied voltage required by traditional electroactive polymers (EAPs). This innovative approach utilizes CNT yarn permeated with a mixture of elastomer and methanol, facilitating phase transition-based actuation, which is promising for creating more human-like prosthetic devices. However, challenges exist in the dispersion of CNTs within polymer matrices, which is critical for achieving the desired enhancement in mechanical properties. Studies have shown that the method of preparation and the concentration of CNTs significantly influence the mechanical properties of the resulting composites. For instance, while certain concentrations of single-walled carbon nanotubes (SWCNTs) in polymer films have been found to increase polymer strength, higher concentrations can decrease both strength and extensibility, indicating the importance of optimizing CNT content for desired mechanical outcomes. Moreover, the hybridization of CNTs with other fillers, such as inorganic compounds, has been explored to improve dispersion and combine desirable properties, which could be particularly beneficial for prosthetic applications where a balance of mechanical strength, durability, and flexibility is essential. In summary, the literature suggests that while CNTs offer significant potential for enhancing the mechanical properties of polymer composites for prosthetics, careful consideration of CNT type, concentration, and composite preparation methods is crucial to fully realize these benefits.
