The cryogenic thermal expansion and mechanical properties of plasma modified ZrW2O8 reinforced epoxy

▶ ZrW2O8 can efficiently reduce the CTE of epoxy resin. ▶ A thin organic coating was uniformly deposited on the surfaces of the ZrW2O8 particles via PECVD. ▶ The Schapery's model provides a good estimate to the thermal expansion behavior of ZrW2O8/epoxy composite. ▶ At both cryogenic and room temperatures, mechanical properties were improved by adding ZrW2O8 to a certain content.
