摘要:
以两亲性的硬脂醇聚氧化乙烯基醚(AEO)为改性剂,采用表面包埋改性的方法对聚丙烯(PP)表面进行亲水改性。通过接触角、扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FT-IR)等分析方法,研究了表面溶胀、退溶胀、改性剂结构等因素对表面改性效果的影响。结果表明:经二甲苯(二甲苯在混合溶剂中的质量分数为80%)与环己酮混合溶剂溶胀处理,溶胀层位于PP表面的无定形区。以AEO-8为改性剂,采用真空干燥的退溶胀方式,改性表面的接触角低至20.6°。相分离及水取向作用能够促进改性剂的聚环氧乙烷(PEO)亲水段向包埋表面外层迁移,并赋予表面亲水性。
Abstract:
An entrapping modification on polypropylene(PP)surface with amphiphilic stearyl-alcohol poly(ethylene oxide)ether(AEO)modifiers was carried out to improve the surface hydrophilicity.Based on analyses of contact angle,scanning electron microscopy(SEM)and Fourier transform infrared spectroscopy(FT-IR),effects of swelling agents,deswelling ways and block structures of AEO modifiers on surface hydrophilicity of modified surfaces were evaluated.Under the surface swelling by the mixed solvent of xylene/cyclohexanone(with 80% xylene),the swelling layer was proved to be located in the amorphous area of PP surface.After the entrapping modification with AEO-8 modifier and deswelling way of vacuum drying,an optimal contact angle of 20.6° was reached on the modified surface.It is believed that both effects of the microphase separation and water orientation on poly(ethylene oxide)(PEO)segment of AEO would promote the migration of PEO towards the outmost PP surface and offer the surface hydrophilicity.
