Paper Title:
Research for Damping Behavior and Microstructure of Interpenetrating Polymer Networks Based on Multi-Components
  Abstract

Based on the molecule design and energy absorption theory of polymer macromolecule materials, we synthesized a kind of multicomponents interpenetrating polymer network(IPN) which composed of polyurethane(PU), epoxy(EP) and unsaturated polymer resin(UPR). In order to further widen the damping temperature region of polymer materials, we introduced the polydimethylsiloxane (PDMS) into polyurethane(PU). Because of solubility parameter difference between PDMS and PU, we synthesized PDMS modified PU by blocking and grafting PDMS chain into PU main chain firstly. Then, a serious of interpenetrating polymer networks (IPN) which composed of PDMS-PU, EP and UPR were designed and synthesized. The damping performance and microstructure were characterized by using the spectrum of dynamic mechanical thermal analysis (DMTA) and the scanning electron microscope(SEM) respectively. The tested result indicated that the multicomponents IPN which modified by PDMS has wider temperature range and higher damping loss factor, and the PDMS grafting PU/EP/UPR shows good damping performance and microphase compatibility specially.
