An article comprises a carbon fibre reinforced plastic (CFRP) substrate, a buffer layer disposed adjacent the substrate, the buffer layer comprising a poly(para-xylylene) polymer; and a moisture barrier coating disposed adjacent the buffer layer.

A method for depositing coating onto a substrate includes providing a monomer for creation of a protective coating on a substrate, energizing the monomer with a plasma generation system, and polymerizing the energized monomer onto the substrate in a plasma-enhanced chemical vapor deposition (PECVD) chamber.

A dental article such as a dental tray aligner or a dental crown that includes a substrate including a polymeric material having a modulus of elasticity that reduces upon exposure to water and a water-resistant coating on the substrate, where the water-resistant coating comprises parylene. In some examples, the water-resistant coating may include one or more layers that include parylene.

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.
