What is the effect of carbomer on rheology of hydroxypropyl cellulose solution?
Best insight from top research papers
Carbomers, such as Carbopol (PAA), are known to form low viscosity acidic solutions that gel with increasing pH . When combined with viscosity-enhancing polymers like hydroxypropyl methylcellulose (HPMC), the rheological properties of the resulting gels can be finely tuned to offer a broader range of viscoelastic characteristics through the formation of physical networks . The addition of HPMC to PAA gels can further modify the viscosity, allowing for precise control over the rheological behavior of the system . This combination of Carbopol and HPMC can lead to the development of gels with tailored viscoelastic properties, making them suitable for various applications where rheological control is crucial.

What is the effect of glycerol mono stearate on rheology of hydroxypropyl cellulose solution?5 answersThe effect of glycerol on the rheology of hydroxypropyl cellulose (HPC) solutions has been extensively studied. Glycerol, at concentrations between 3% and 5%, increases the viscosity of HPC polymer dispersions without altering their rheological behavior. Additionally, interactions between HPC and surfactants like sodium laurylsulfate (SDS) can modify the physicochemical properties of the system. In HPC-SDS solutions, viscosity changes are dependent on the HPC-SDS interaction, with viscosity increasing up to a maximum at specific SDS concentrations before decreasing to a constant value. Furthermore, the phase behavior of HPC in mixed solvents of glycerol and water has been investigated, highlighting the molecular processes of phase separation and the temperature-dependent chain rigidity of HPC.
How hydroxymethyl cellulose HMC HPMC is used for agricultural use and helps in water retention?5 answersHydroxypropyl methyl cellulose (HPMC) is used in agriculture for water retention purposes. HPMC forms a colloidal film with a 3D network structure in water, which changes the ability of water to migrate. It adsorbs on the surface of cement and sand particles, playing a bridging role due to the influence of the spatial network structure of the thin film. This results in a grid-like distribution of fine particles and a unique fibrous tree-like structure of hydration products. The plastic viscosity of cement mortar is positively correlated with the water holding capacity, indicating that HPMC improves water retention in cement mortar. This is achieved by changing the water migration capacity, migration channels, and mortar cohesion.
What are the effects of different additives on the rheology of crude oil mixtures?5 answersDifferent additives have various effects on the rheology of crude oil mixtures. Surfactant and stabilizing polymer additives can reduce the viscosity of heavy oil by transforming it from Newtonian behavior to a viscoplastic medium. Ionic liquids (ILs) as additives in lubricants can decrease friction and increase viscosity. Diluents such as n-heptane, toluene, and toluene + butanone can modify the non-Newtonian behavior of crude oil, with toluene + butanone being the most effective in reducing shear thinning behavior. Polymeric additives with different structures can improve the pour-point depression and rheological behavior of waxy crude oil. Oil wetter and rheology modifier additives can affect the rheology of oil-based drilling fluids, decreasing rheology parameters and emulsion stability.
What are the effects of cellulose fiber admixtures on the rheological properties of bitumen and hot mix asphalt?2 answersCellulose fiber admixtures have been found to have various effects on the rheological properties of bitumen and hot mix asphalt. The addition of cellulose fibers to bitumen has been shown to improve its rheological properties, including increasing the softening point and viscosity, and reducing the penetration. These improvements suggest enhanced rutting resistance and improved fatigue performance of asphalt mixtures using cellulose fiber-modified bitumen. Additionally, the use of cellulose fibers in hot mix asphalt mixtures has been found to improve the mechanical properties, such as the dynamic modulus and phase angle, of the mixtures. The application method of cellulose fibers, whether dry or wet, has been found to have an impact on the mechanical properties of the fiber-reinforced asphalt mixtures. Overall, the addition of cellulose fibers as an admixture in bitumen and hot mix asphalt has shown promise in enhancing their rheological and mechanical properties.
How does glycerol affect the properties of a cellulose based bioplastic?5 answersGlycerol has been found to have a significant effect on the properties of cellulose-based bioplastics. The addition of glycerol as a plasticizer to cellulose films increases their tensile strength and elongation at break, resulting in improved flexibility and mechanical properties. However, the effect of glycerol on cellulose acetate (CA) films varies depending on the purpose of application. The addition of glycerol into CA films increases thickness, opacity, and water vapor permeability, while films plasticized with triethyl citrate (TEC) exhibit opposite behavior. Glycerol also plays a crucial role in enhancing the biodegradability of bioplastics. The application of glycerol as a plasticizer in carrageenan waste cellulose bioplastics significantly improves their ability to biodegrade, with the highest value observed at a concentration of 5-7%. Additionally, glycerol can be used as a renewable carbon source to produce bacterial cellulose (BC) through more efficient and environmentally friendly bioprocesses, reducing the costs associated with BC production. Overall, glycerol has a positive impact on the properties of cellulose-based bioplastics, improving their mechanical properties, biodegradability, and production efficiency.
How is Hydroxypropylcellulose formed ?5 answersHydroxypropylcellulose (HPC) is formed through various methods. One method involves the reaction of alkali cellulose with propylene oxide in an aliphatic ketone solvent, such as methyl isobutyl ketone, methyl n-amyl ketone, or methyl n-hexyl ketone. Another method includes the preparation of HPC films by casting with cellulose nanocrystals in the presence of anionic surfactant sodium dodecylsulphate (SDS) and cationic surfactant hexadecyltrimethyl ammonium bromide (CTAB). Additionally, a novel polymeric porous membrane made of HPC can be developed without the use of any organic solvent by dissolving HPC in water and inducing phase separation through temperature changes. Furthermore, a method for the preparation of hydroxypropyl emthylcelluloses involves the alkali reaction of purified cottons with caustic alkali or sodium hydroxide, followed by etherification reaction with methyl chloride and propylene oxide. Finally, HPC form parts can be produced through thermoplastic processing of HPC polymer or HPC blends, followed by chemical crosslinking of HPC through methods such as irradiation or thermal treatment.
