Abstract

Abstract:

The polylactic acid/formylated bagasse cellulose(PLA/BFC) composite membrane was prepared by formylation, using bagasse as raw material. The structure and properties of the composite membrane were analyzed by SEM, XRD and electronic universal testing machine. The formylation process of bagasse cellulose was optimized by response surface method. Under the optimal conditions of formic acid mass fraction of 85%, particle size of 180-400 μm and reaction temperature of 100 ℃, the mass fraction of formyl group in bagasse cellulose was 6.44%. PLA/BFC composite film was prepared by formacylated bagasse cellulose with different formacylated contents. The experimental results showed that the addition of BFC changed the structure of PLA/BFC film and made the cross section more uniform. The crystallization index of PLA/BFC composite film increased with the increase of formyl group content, and the addition of formyl cellulose had a complementary effect on the PLA/BFC composite film. At the same time, the content of formyl group in cellulose will affect the mechanical properties of the composite film. Compared with the pure PLA film, the elongation at break of PLA/BFC composite film(the degree of formylation was 6.51%) increased by 44.90%, the tensile strength increased by 32.54%, and water absorption decreased by 50.62%. The toughness, tensile properties, and water resistance of PLA/BFC composite film were better than that of the pure polylactic acid film.

Key words: bagasse cellulose, formylation, polylactic acid composite membrane, mechanical property test
