Abstract:
1. A method of protecting an object comprising: (a) reacting at least one acid monomer with at least one diamine monomer to form a polyamic acid backbone, where the monomers are selected such that the polyamic acid backbone includes a non-terminal attachment point; (b) after step (a), imidizing the polyamic acid backbone to form a polyimide polymer backbone; (c) after step (b), attaching an oligomeric silsesquioxane (OS) compound to the attachment point on the polyimide polymer backbone, such that the OS compound is connected to the polyimide polymer backbone; (d) providing an object with a surface; (e) protecting the surface from atomic oxygen and ultraviolet light with a polymeric coating, where the polymeric coating includes the polyimide polymer backbone.
