Preparation and Properties Study of Waste Cotton Microcrystalline Cellulose/Polylactic Acid Composite Films
Utilizing waste cotton as a source of microcrystalline cellulose (MCC), octadecylamine-melamine formaldehyde resin (OMF) was employed for hydrophobic modification to obtain OMF-MCC as a reinforcing material for waste cotton microcrystalline cellulose/polylactic acid composite films (OMF-MCC/PLA). Material characterization and mechanical properties tests were conducted on pristine and modified waste cotton MCC and the OMF-MCC/PLA composite films. The results showed that the MCC extracted from waste cotton textiles had a smooth surface with wide size dispersion, and OMF modification increased the hydrophobicity of waste cotton MCC successfully. Compared to the pure PLA films, the tensile strength of the OMF-MCC/PLA composite films was enhanced significantly with the addition of OMF-MCC, maximally increased by 166.6%. The elongation at break of OMF-MCC/PLA composite films only experienced a slight decrease. The obtained OMF-MCC/PLA composite films demonstrated excellent mechanical properties.
