摘　　要：为改善聚乙烯醇(PVA)对相变材料十二酸十二酯(PCM)的包封稳定性与力学性能,以经戊二醛交联改性的复合分子量共混PVA作为支撑材料、以十二酸十二酯作为相变材料,采用乳液静电纺丝技术制备了PCM/PVA蓄热调温纤维。采用旋转流变仪、扫描电镜、差示扫描量热仪、温度记录仪、热红外成像仪、多功能拉伸仪等研究了O/W型PCM/PVA纺丝液的组成及电纺纤维的表面形貌、储热性能、调温性能和力学性能等。研究结果表明,以不同相对分子质量的PVA_(1)和PVA_(2)共混制备复合PVA,当PVA_(1)与PVA_(2)质量比为3:7,PVA质量分数为14.0%,PCM与PVA质量比为50∶100时,PCM/PVA纺丝液具有良好的稳定性和可纺性。电纺PCM/PVA纤维具有良好的蓄热调温性、热循环稳定性、耐水稳定性和力学性能,热处理后PCM/PVA电纺纤维中的PCM几乎无泄露。In order to improve the encapsulation stability and mechanical properties of poly(vinyl alcoho)(PVA)to phase change material dodecyl dodecate(PCM),PCM/PVA thermo-regulated fibers were prepared by emulsion electrospinning with the compund PVA of different molecular weight crosslinked by glutaraldehyde as support material and dodecanol dodecanoate as phase change material.The composition of O/W type of PCM/PVA spinning solutions and the surface morphology,heat storage performance,temperature regulation performance and mechanical properties of electrospun fibers were studied by rotational rheometer,SEM,DSC,temperature recorder,thermal infrared imager and multifunctional tensile tester.The results show that when the mass ratio of PVA_(1)to PVA_(2)is 3∶7,mass fraction of PVA is 14.0%,and mass ratio of PCM to PVA is 50∶100,the PCM/PVA spinning solution has a good stability and spinnability.The electrospun PCM/PVA fibers have the good thermal storage and temperature regulation,thermal cycle stability,water resistance stability and mechanical properties,and there is almost no leakage of PCM in the PCM/PVA fibers after heat treatment.
