Abstract Details

2016, Master of Science, University of Akron, Polymer Science.
A series of branched L-valine based poly(ester urea)s with different branching degrees and molecular masss were synthesized and characterized. In this work, two monomers bis-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 made using various molar ratios of the two monomers during interfacial polymerization. It was found that high molecular mass branched L-valine-based PEUs exhibit higher glass transition temperature, higher elastic modulus and improve the stability of nanofibers throughout sterilization and in physiological conditions compared to their linear analogues. High molecular mass (MW = 379 kDa) PEU nanofibers containing 2% of the branching agent maintained their morphology in physiological conditions, which suggest that these materials can be developed further for biomedical applications such as drug delivery and tissue engineering.
