摘要：

A series of pyromellitic dianhydrides (PMDAs)-4,4'-oxydianiline (ODA) polyimide nanocomposite films with modified beta-cyclodextrin (CD) were prepared via in situ polymerization and subsequent thermal imidization. The effect of CD modified with the functional group of -NH2 on the mechanical properties and dielectric constant of the nanocomposite films were investigated. The tensile strength and modulus of the nanocomposite films containing modified CD were higher than the neat PI. The dielectric constant decreased with increasing content of the modified CD up to 10 wt% from 3.34 for neat PI to 2.56.
