Zea Mays Cob Extract-containing Polyurethane Nanofiber Webs

초록

Even though nanofibrous materials have excellent protectability against microorganisms such as bacteria and virus, their functionality can be upgraded by incorporating natural substances with diverse bioactivities and biocompat-ibility. In this study, Zea mays cob extract (ZME)/polyurethane (PU) nanofiber webs were fabricated by ZME-doped elec-trospinning of PU, and their physical characteristics and bioactivities were investigated. Based on the observation by scanning electron microscope, the diameter and pore size of ZME/PU nanofiber decreased as compared with those of PU nanofiber. ZME/PU nanofiber webs had a certain level of absorptivity in that a significant decrease of water contact angle below 80 degrees was revealed within 10 sec, while PU nanofiber web had very little wettability. Moreover, ZME/PU nanofiber webs had antioxidative activity and antimicrobial activity of 99.9% without any cytotoxicity, suggesting that they can be applied to healthcare and biomedical materials for antiaging and wound healing.
