In this work, two monomersbis-L-valine-decane-1,10-diester (Diol-1-VAL-10) and tri-O-phenylalanine-1,1,1-trimethyl ethane-triester (Triol-PHE) were synthesized, along with copolymers madeusing various molar ratios of the two monomers during interfacial polymerization. It wasfound that high molecular mass branched L-valine-based PEUs exhibit higher glasstransition temperature, higher elastic modulus and improve the stability of nanofibersthroughout sterilization and in physiological conditions compared to their linearanalogues. High molecular mass (MW = 379 kDa) PEU nanofibers containing 2% of thebranching agent maintained their morphology in physiological conditions, which suggestthat these materials can be developed further for biomedical applications such as drugdelivery and tissue engineering. 2016-06-10 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1460402230 http://rave.ohiolink.edu/etdc/view?acc_num=akron1460402230 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
