Abstract
Surface-initiated atom transfer radical polymerization (SI-ATRP) is successfully applied to electrospun constructs of poly( L -lactide). ATRP macroinitiators are adsorbed through polyelec-trolyte complexation following the introduction of negative charges on the polyester surface through its blending with a six-armed carboxy-terminated oligolactide. SI-ATRP of glycerol monomethacrylate (GMMA) or 2-(N,N-diethylamino)ethyl methacrylate (DEAEMA) allows then to grow surface fi lms with controllable thickness, and in this way also to control the wetting and interactions of the construct.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
