Abstract
Aspects herein relate to biocompatible polyisobutylene-fiber composite materials and related methods. In one aspect a biocompatible composite material is included. The biocompatible composite material can include a network of fibers comprising one or more polymers to form a substrate and a continuous polyisobutylene matrix that is non-porous and completely surrounds the electrospun fibers. Other aspects are included herein.
Claims16
A biocompatible composite material comprising:
- a network of fibers comprising one or more polymers to form a substrate;
- and
- a continuous polyisobutylene matrix that is non-porous and completely surrounds fibers of the network of fibers;
- wherein the continuous polyisobutylene matrix comprises polymerized methacrylate-endcapped telechelic PIB (PIB-DMA), acrylate-endcapped telechelic PIB (PIB-DA), monofunctional methacrylate-PIB (PIB-MA), or a star-PIB derivative having 3 or more branched side chains.
