Abstract: Abstract This paper reports the discovery that free-standing rubbery fiber mats can be electrospun from polyisobutylene-based thermoplastic elastomer/poly(ethylene glycol) mixtures from a THF-toluene solution. Direct contact and elution cytotoxic assays of these mats showed no… read more here.
