A coating for a medical device or appliance may include a fluoropolymer and a polyimide. Such coatings may provide a lubricious exterior surface that facilitates insertion or displacement of a medical device in a body lumen. Some coatings that include a fluoropolymer and a polyimide may, among other functions and characteristics, provide increased strength and/or durability relative to some other coatings.

Method for pore sealing a porous substrate, comprising: forming a continuous monolayer of a polyimide precursor on a liquid surface, transferring said polyimide precursor monolayer onto the porous substrate with the Langmuir-Blodgett technique, and imidization of the transferred polyimide precursor monolayers, thereby forming a polyimide sealing layer on the porous substrate. Porous substrate having at least one surface on which a sealing layer is provided to seal pores of the substrate, wherein the sealing layer is a polyimide having a thickness of a few monolayers and wherein there is no penetration of the polyimide into the pores.

A method for curing photosensitive polyimide (PSPI) films includes the steps of: depositing a PSPI film on a selected substrate, and curing the film by microwave heating at a selected temperature from about 200 to 340? C. in a selected atmosphere containing an oxygen concentration from about 20 to 200,000 ppm. The process atmosphere may be static or flowing. The addition of oxygen improves the removal of acrylate residue and improves the T.sub.g of the cured film, while the low processing temperature characteristic of the microwave process prevents the oxygen from damaging the polyimide backbone. The method may further include the steps of photopatterning and developing the PSPI film prior to curing. The process is particularly suitable for dielectric films on silicon for electronic applications.

Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.
