Fabrication, Characterization of Multifunctional Tetrapod-ZnO/Polymer Composites for Bioinspired Applications — •Xin Jin, Xinwei Zhu, Sebastian Wille, Arnim Schuchardt, Yogendra Kumar Mishra, and Rainer Adelung — Functional Nanomaterials, Institute of Materials Science, CAU Kiel, Germany

Composite materials design is a fascinating research subject because of the challenge to combine the functionalities of each component and simultaneously give improved properties to the entirety. In biomedical researches, polymers composites play a key role as hard tissue restoratives, like prosthetics, dental implants, etc. One of the most important methods to improve the performance of polymers composite, is to alter the type, amount and size of the filler material. In this work, composites of tetrapods-ZnO micro/nano-particles embedded in PDMS matrix are fabricated. Tensile tests, photon-responsive IV characterization and wettability tests are performed. The results show favorable change in mechanical and electrical properties induced by the special shape of filler. The mechanism of reinforcement is discussed. Researches of this composite material in bio-inspired adhesion applications are in progress. Experiments of tetrapod-ZnO as fillers for dental polymer are also performed.
