摘要: A triblock copolymer based on poly(e-caprolactone) (PCL) and 2-(N,N-diethylamino)ethyl methacrylate (DEAEMA)/2-(methyl-7-nitrobenzofurazan)amino ethyl acrylate (NBD-NAcri), was synthesized via atom transfer radical polymerization (ATRP). The corresponding chlorohydrated copolymer, named as PCL-b-DEAEMA, prepared anchored cationic exchange montmorillonite (MMT) surface. (PCL)/layered silicate nanocomposites were through melt intercalation, XRD TEM analysis showed an exfoliated/intercalated morphology for organomodified clay. surface characterization of the undertaken by using contact angle AFM. An increase in observed PCL/MMT(PCL-b-DEAEMA) with respect to PCL. AFM that became rougher PCL when MMTk10 or MMT(PCL-b-DEAEMA) incorporated, value increased clay content. antimicrobial activity ...
