| Popis: | A small amount of cyano groups in poly(styrene-co-acrylonitrile) (SAN) was converted to oxazoline groups through reaction with 2-aminoethanol. Reactive melt blending of oxazoline-containing SAN and acidified multiwalled carbon nanotubes (MWCNTs) leads to the grafting of polymer chains onto MWCNTs arising from reactions between oxazoline and carboxylic acid groups. Spectroscopic, thermal and microscopic techniques confirmed the successful grafting of SAN onto MWCNTs. This method is comparatively simpler and greener than a previously reported method, and can be adopted to graft other acrylonitrile-containing polymers onto MWCNTs. |
