摘要: Biodegradable acrylate-terminated polyurethane/acrylate (APUA) filled with 2-hydroxyethyl methacrylate functionalized carbon nanotube (CNT-HEMA) was prepared by in situ free radical crosslinking. CNT-HEMA enhanced crystallinity of soft domain and caused more phase separation between hard domains APUA. Tensile testing showed a considerable improvement elastic modulus (∼160%) tensile strength (∼30%) at 1 wt% loading. Morphological features APUA induced nanotubes were found to be dominant on mechanical properties APUA/CNT-HEMA. increased water contact angle APUA; however, wettability APUA/CNT-HEMA maintained acceptable range for biomedical applications. exhibited lower hydrophobic nature compared many CNT polyurethanes reported literature due HEMA functional group, making nanocomposites adequate POLYM.
