Abstract

Abstract : To enhance the adhesion and polymerization of lipase‐plasma‐polymerized‐ethylene (lipase‐PPE) coatings deposited by aerosol‐assisted atmospheric plasma deposition (AAAPPD), the effects of voltage, ceramic‐dielectric thickness, and pre‐coated PPE layer were investigated. In AAAPPD system, ethylene and lipase‐phosphate‐buffered‐saline aerosol were used as precursors to polymerize ethylene and embed lipase simultaneously. The deposited lipase‐PPE coatings were analyzed with FTIR, SEM, and surface profiler. The results show that increasing voltage from 3 to 4 kV and decreasing ceramic‐dielectric thickness from 1 to 0.38 mm improved the coating adhesion and polymerization. Also, depositing a PPE layer with high energy prior to lipase‐PPE coating enhanced adhesion. These improvements of the biomolecule‐PPE coatings facilitate further bioapplications of this new biomolecule‐embedding method. Abstract : In this study, the adhesion and polymerization of the aerosol‐assisted atmospheric‐pressure plasma deposition (AAAPPD) deposited lipase‐plasma‐polymerized ethylene (lipase‐PPE) coatings were improved by increasing applied voltage, decreasing ceramic‐dielectric thickness, and adding a pre‐coated PPE buffer layer. According to the results, we also hypothesized the related mechanisms of the AAAPPD process.
