Surface Migration of Additives in Polymers
EMSL Project ID
12299
Abstract
Field-induced migration of oligomers dispersed in a host polymer is a promising method for modifying the host polymer’s surface to improve properties such as paintability, biocompatibility, and adhesion. This approach to polymer surface functionalization is attractive because it allows surface functionalization and plastics shaping to be performed using the same polymer processing equipment. The method relies on the fact that the concentration distribution of an additive dispersed in a host polymer can be manipulated by flow fields, surface energy gradients, and additive/host polymer architecture. The proposed research combines theory and experiment to advance current understanding of this phenomena. PNL facilities will allow us to quantify the composition profiles of additives in polymers. This information will be used to guide theoretical developments.
