地點:國家重點實驗室BC樓四樓中庭會議室

主講人介紹:薛龍建,2004年,從武漢大學化學基地班獲學士學位,2010年從中國科學院長春應用化學研究所獲得博士學位,2009-2015在德國多所大學和研究所(亞琛工大、奧斯納布呂克大學、基爾大學、馬克斯普朗克聚合物研究所)從事科學研究工作,期間獲得了洪堡學者獎學金和馬普學者獎學金。2015年獲得中組部“千人計劃”青年項目,受聘武漢大學動力與機械學院材料系。研究領域包括聚合物薄膜、微納結構制備、仿生功能材料、增材制造等。

主要內容:In order to survive into the natural environment, tree and torrent frogs have to attach, climb and jump in humid or flooded environments. For this purpose, their limbs developed digits with expanded adhesive pads and specialized surface topography. Irrespectively of habitat and phylogeny, tree and torrent frog digits display hexagonal arrays of (soft) epithelial cells separated by narrow channels and crossed by densely packed (hard) keratin fibrils. Inspired by the hierarchical structures found on tree frog’s toe pad, micro- and nano-patterns with a hybrid and anisotropic structure have been realized. Depending on the specialized surface design, enhanced adhesion and/or friction could be achieved. The results here give a hint to the design of new materials with both strong adhesion and friction based on composite structures with anisotropic designs.
