A substrate surface may be modified with a polymer coating to render the surface suitable for plasma functionalization. The polymer coating is deposited onto the surface at ambient temperature to a thickness of less than 0.1 μm. The polymer coating includes poly(p-xylylene) or a derivative thereof, and is capable of penetrating into pores of a porous substrate while no substantially altering the porosity of the substrate. The coated substrate is selected from a material lacking a primary or secondary aliphatic hydrogen atom.

This invention provides a resin composition for preparing an allylphenol-maleimide copolymer used for a protective film for an electronic component including: (A) an allyl group-containing phenol compound having a rigid structure; (B) an N-aromatic maleimide group-containing compound having a rigid structure; and (C) an N-aliphatic maleimide group-containing compound having a flexible structure.

Films including a water-soluble layer and a vapor-deposited organic coating are disclosed. The films can optionally further include a vapor-deposited inorganic layer. The films exhibit enhanced barrier properties.

Design, fabrication and applications of three-dimensional (3D) bioreactor for cell expansion and cell secreted substance production. The bioreactors have relatively low levels of potentially cytotoxic compounds, can be coated with substituted or unsubstituted poly(p-xylene) type coatings and can also be separately formed from liquid crystal photopolymerizable monomers.

The present disclosure provides a composite coating and a method for fabricating the composite coating. The composite coating comprises a polymer layer, a metal interlayer and an amorphous metal coating. The polymer layer is formed on a substrate and acts as a diffusion barrier layer, which is thick and dense enough to prevent the corrosive substances from penetrating into the substrate. The metal interlayer is formed between the polymer layer and the amorphous metal coating for improving the adhesion of the amorphous metal coating to the substrate.
