Cellulose nanocrystals from cotton stalks for reinforcement of poly vinyl alcohol composites - a research study - Projects
Updated : October 2020
This study presents an innovative avenue of extracting cellulose and cellulose nanocrystals from waste cotton stalks for using them as a reinforcement material in polyvinyl alcohol composites.
It involved detailed chemical and morphological characterization of cotton waste stalks, extracting cellulose nanocrystals and testing their potential for use as a reinforcing material on polymer films using solution casting technique.
Results showed that use of certain concentrations of chemicals could result in high quality nanocrystals extraction and using 3 wt% of crystals in polymer films could enhance their tensile strength and modulus. However, further research is needed in this regard.
