Bio-inspired Self-Sealing Hydrogel for Medical and Battery Applications
이해신 한국공업화학회 2018 한국공업화학회 연구논문 초록집 Vol.2018 No.0
Catecholamines are found ubiquitously in nature. Wetting-resistant, adhesive foot-pads in mussels, neurotransmitters in the brain, melanin bio-pigments in the skin and eyes, squid beaks, and insect cuticles are related examples. The material-independent coating properties are developed only when both catechol and amine moieties coexist in a polymeric backbone. In contrast, when the both moieties are ‘not’ covalently linked, they exhibit self-sealing properties at liquid/air interfaces. Self-sealing conceptually mimics biological healing processes in which precursors at internal liquid are polymerized and/or crosslinked at liquid/air interfaces rather occurring at a bulk liquid. This seminar will present a hemostatic needle which results in blood vessel self-sealing exhibiting no bleeding after needle injection and withdrawal.
