    Abstract: A method of powder coating thermo powder resins to non-conductive plastic substrates, in particular, to polyamide materials and other non-conductive plastic substrates. After cleaning the substrate, a water-based adhesive/primer is applied to the substrate and then cured to promote adhesion, protect the substrate from unwanted chemical reactions and increase the electrical surface conductivity of the substrate to provide to better coating and transfer efficiency of the thermosetting powder to the substrate.

    Abstract: Articles produced from hydrophobic polymers (e.g., polyethylene) are surface-coated with thin films of starch in order to render the surfaces hydrophilic. The thin coatings form on the surfaces of plastic objects when the objects are placed in contact with hot, aqueous solutions of starch. These starch coatings are adherent to the hydrophobic plastic surfaces under both wet and dry conditions, and they permit the surfaces to be uniformly wet with water. The coatings may be rendered even more adherent when wet by graft polymerizing the starch with a synthetic monomer. Resultant products have the potential for improved biocompatibility, improved compatibility with hydrophilic reagents, reduced build-up of electrostatic charge, reduced blocking, reduced friction, improved absorption of water-based dyes, and improved adhesion properties. The starch coatings are non-toxic, inexpensive and biodegradable.

    Abstract: One aspect of the present invention relates to a method for modifying one side of a PTFE membrane by using HFCVD to deposit a PTFE film on one side of the PTFE membrane. The precursor fluorocarbon gas is preferably hexafluoropropylene oxide, which upon pyrolysis under HFCVD conditions forms reactive CF2 species. The present invention also relates to a modified PTFE membrane having a PTFE film on only one side, wherein the PTFE film has a porosity of greater than about 30% and a dangling bond density of less than about 1018 spins/cm3. The invention further provides a method of filtering a liquid or gas or a mixture of the two, comprising passing the liquid or gas or mixture of the two through the modified PTFE membrane of the present invention.

The thin coatings form on the surfaces of plastic objects when the objects are placed in contact with hot, aqueous solutions of starch.

Resultant products have improved biocompatibility, improved compatibility with hydrophilic reagents, reduced build-up of electrostatic charge, reduced blocking, reduced friction, improved absorption of water-based dyes, and improved adhesion properties.
