摘要
Abstract
To improve the compatibility between enzymatic lignin and bio-based poly(propylene carbonate)(PPC)and to endow PPC with UV resistance,acetylated lignin(ACEL)was prepared through an acetylation reaction and then was melt blended with PPC to obtain PPC-based composites.When 15 wt%(mass fraction,same below)ACEL was incor-porated,the composites showed an increase in the yield tensile properties from 10 to 23 MPa,and their elongation at break reached 725%.Meanwhile,the addition of ACEL also endows PPC with excellent UV resistance.After 96 h UV irradiation,the PPC-ACEL-15 composites showed retention rates of all above 80%in the yield strength and elonga-tion at break.These results are significantly better than those of pure PPC and PPC-EL-15 composites.关键词
