摘要

Polypropylene/butenediol vinyl alcohol copolymer (PP/BVOH) blends with varying mass ratios were fabricated via melt-blending. PP and BVOH were incompatible in PP/BVOH blends. The addition of BVOH enhanced the crystallization of PP, whereas PP had only a minor influence on the crystallization of BVOH. The hydrophilicity of PP/BVOH blends was enhanced. When the content of BVOH increased from 0 to 90%, the water contact angle of PP/BVOH decreased from 104.3 to 80.7° in 120 s. In addition, PP/BVOH/curcumin fibers with 5% curcumin were manufactured by melt-spinning. As the content of BVOH in PP/BVOH blend fibers rose from 0 to 40%, the percentage of curcumin release over 188 h increased from 0.85 to 1.06% gradually, and the percentage of free radical scavenging rose from 6.02 to 87.65%.
