摘要

Abstract

Modified castor oil-based epoxy resin (EP)/polyurethane (PU) grafted copolymer by glycidyl polyhedral oligomeric silsesquioxane (glycidyl POSS) was synthesized. The damping properties

thermal stability

mechanical properties and morphology of the grafted copolymer modified by glycidyl POSS were studied systematically. The results revealed that the incorporation of glycidyl POSS improved the damping performance evidently and broadened damping temperature range

especially when the glycidyl POSS content was 0.2%–1%. At the same time

there was a slight increase in thermal stability with the increase of POSS content. The tensile properties changed with the change of the copolymer’s

decreased at low POSS contents and increased at high POSS contents. This modified copolymer has the potential to be used as film damping material or constrained damping layer.
