Abstract:Polyimide
(PI) aerogel is a good thermal insulation material with
the highest temperature resistance in practical application. But the
mechanical strength of PI aerogels prepared by freeze-drying or thermoimide
methods is weak. In this research, TPU was selected as an aging solution
to solve the problem of the low mechanical strength of PI aerogel
prepared by the freeze-drying method. Previous work has certified
that the coupling of PI and thermoplastic polyurethane (TPU) can enhance
the mechanical strength of… Show more
