摘要

为研究掺杂纳米SiOZ对EVOH磺酸铿( EVOH-S03 Li)无纺布形貌及热特性影响，以聚乙烯一乙烯醇(EVOH)和1

3一丙烷磺酸内醋为原料，叔丁醇铿为催化剂，合成EVOH磺酸铿接枝聚合物，并进行纳米SiOZ掺杂改性，经静电纺丝制备出EVOH-S03Li

EVOH一S03 Li/SiOZ两种无纺布;应用扫描电镜观察分析了无纺布的微观形貌，并通过差示扫描量热仪及热失重仪对无纺布热性能进行研究分析;结果表明:经纳米SiOZ改性后，纤维直径降低，分布在0. 1 } 0. 2 N.

m之间，无纺布结晶度升高，熔点提高35 0C，起始热分解温度升高30 0C .

Abstract

To study the influence of SiOznn macrocosmicmorphology and thermal properties of EVOH一S03 Linon-woven，with Lithium Tert-butoxide asthe catalystend-capped with lithium sulfonate(EVOH一S03Li)a polymer electrolyte of poly(ethylene-co-vinyl alcohol)synthesized from poly(ethylene-co-vinyl alcohol) and were added into EVOH-S03Li solution and the EVOH一S03 Li，EVOH一S03 Li/SiOz non-woven membraneswere prepared by electro一spinning technique. Scanning Electron MicrosG’Ope W9sutilized to characterize the features microcosmic of the non-woven，meanwhile，Differential Scanning Cal-orimetry and Thermal gravimetric analyzer wereused to characterize thermal properties of the non-woven. Thecults showed that，with the addition of SiOz，the fiber diameter of non-woven membraneW9
