Study on the Preparation and Properties of Low Permeability Coating

Abstract:

Fluorinated amorphous carbon (a-C:F) films have long attracted much consideration due to their low surface energy, hydrophobicity, low refractive index, good electrical and thermal insulation and good thermal stability, and so on. To repair of some polymer films that have good flexibility and low permeability, F₂₃₁₄ resin was used as main film-forming material of coating in this paper. The solubility parameter of F₂₃₁₄ was estimated by group contribution method, which is 20.548 J^1/2•cm^-3/2. And proper solvents were selected on the basis of the solubility parameter. FEVE resin was selected as one of the components of coating, because of its good adhesion and compatibility. The adhesion of the F₂₃₁₄ coating was improved, and penetration resistance performance of F₂₃₁₄ coating was enhanced to 300(mg•mm)/(m²•h).
