Stability of Aqueous Polymeric Dispersions for Ultra-Thin Coating of Bi-Axially Oriented Polyethylene Terephthalate Films

Stability of Aqueous Polymeric Dispersions for Ultra-Thin Coating of Bi-Axially Oriented Polyethylene Terephthalate Films

The stability of polyacrylate and polyester based aqueous dispersions designed for ultrathin coating of extruded plastic films, especially bi-axially oriented polyethylene terephthalate (BOPET), was studied. Also, the effect of the gemini surfactant based defoaming/wetting agent on the properties of the dispersions was examined. The addition of the defoaming/wetting agent resulted in reducing t...

Annealing of Ultrathin Polyethylene Films from Aqueous Dispersions

Introduction Thin and ultrathin crystalline polymer films are of fundamental scientific and practical interest, e.g. in terms of their mechanical properties or of crystallization in a confined environment. A common route to ultrathin crystalline polymer films is spin-coating from solution, often at high temperature, which involves formation of crystalline structures during solvent evaporation. ...

Aqueous dispersions of extraordinarily small polyethylene nanoparticles.

General methods and materials. Ethylene of 3.5 grade was supplied by Praxair. Demineralised water was distilled under argon. 2-propanol (p.a.) was degassed by four repeated freeze-thaw cycles. Chloranil (Aldrich) und sodium dodecyl sulfate (Fluka) were used without further purification. Potassium 4-(diphenylphosphino)benzenesulfonate (TPPMS) was synthesized as described in [1]. bis(1,5-cyclooct...
