摘要: Polyimides containing a backbone with at least one nanoparticle component and made from oligomers having endcaps that are difunctional or a mix of di- and monofunctionality are provided. The endcaps may be nadic or phenylethynyl. The backbone may be wholly inorganic or made from a mixture of inorganic and organic groups. The oligomers may be created in-situ using standard polymerization of monomeric reactants chemistry using a solvent or may be provided as a pre-imidized compound that may be either a solid or liquid. It is believed that the nanoparticle component of the polymer backbone provides superior thermo-oxidative stability verses unmodified organic backbones. It is further believed that providing difunctional or a mixture of di- and monofunctional endcaps allows for increased crosslinking to provide improved strength and stiffness verses wholly monofunctional endcapped oligomers for polyimides. The nanoparticle is part of the backbone of the polymer and not solely a pendant group.
