摘要(Abstract)：
论述了腈纶表面接枝大豆蛋白质的基本工艺过程与效果,结果表明:腈纶经过表面水解、酰氯化、接枝反应等几个简单步骤就可以接枝上大豆蛋白质表面覆盖层,从而达到对腈纶进行蛋白质化学改性的目的。SEM观察表明:接枝之后,蛋白质将会填充腈纶的表面裂纹与微孔,赋予纤维以新的结构形态。
The basic process and effect of modification of polyacrylonitrile(PAN) fiber by protein surface grafting was studied in this paper. With simple procedures of surface hydrolysis, acidchloride reaction and grafting, the soybean protein could be grafted onto the PAN fiber which endowed the fiber with protein surface, and protein-modified PAN fiber was obtained. SEM photographs showed that after the protein has been grafted, the cracks and pores of the surface of the PAN fiber were filled with protein which gave the fiber new surface and structure. Thus the surface property of PAN fiber changed and the protein-modified function was obtained.
