1.报告会简介

报告人:Claas Willem Visser助理教授

时间:2020年1月6日(星期一) 下午15:30

地点:长安校区理学院214会议室

报告题目:3D printing of multi-scale functional polymer foams

内容简介:Polymer foams are cellular solids composed of solid and gas phases that are widely used as personal protection gear, pressure sensors, thermal insulation, acoustic materials, and scaffolds for artificial tissues. Their mechanical, thermal, and acoustic properties are determined by the respective composition, volume fraction and connectivity of both phases. Therefore, controlling their local architecture is hardly possible with current techniques, since bulk techniques lack control and microfluidic techniques lack the options to create foams with internal gradients. Here we introduce direct bubble writing, a technique for additive manufacturing of locally tunable polymer foams. By ejecting bubbles into the air, depositing them onto a substrate, and polymerizing them in-situ with UV light, open- and closed-cell foams with locally graded densities were printed into programmable macroscopic shapes at throughputs >10 mL min-1. We fabricated graded polymer foams in several motifs, including 3D lattices, shells, and out-of-plane pillars. Through the incorporation of silver nanoparticles, we produced conductive composite foams with controlled stiffness for use as soft pressure sensors. Direct bubble writing opens new avenues for rapidly designing and manufacturing designer polymer foams on demand.
