Mechanical instability of swollen PVC films

Journal of Applied Polymer Science, 1995
AbstractThe swelling of soft coating on a tough substrate immersed in solvent is investigated. Equilibrium aspects of the coating deformation due to swelling as well as its kinetics have been explored; in particular, the appearance of patterns on the originally smooth surface of the swollen film is described and modeled.

PVC film behavior under proton bombardment

Radiation Physics and Chemistry, 1995
Abstract Thin films of poly(vinyl chloride) (PVC) were bombarded with protons of energies between 0.7 and 3 MeV, and the loss of mass was studied using back- and forward-scattering techniques. The abundances of chlorine, carbon and hydrogen were measured simultaneously during the bombardment.

Electron Transport Properties of Cu-Doped PVC Films

Physica Status Solidi (a), 1979
DC conductivity, ac conductivity, dielectric relaxation, and thermally stimulated discharge (TSD) current measurements are made on Cu-doped PVC films as a function of Cu concentration up to 12%. The dc conductivity of doped films increases by several orders up to a concentration of 4% and thereafter changes little for higher concentrations.

Bioremediation of polyvinyl chloride (PVC) films by marine bacteria

Marine Pollution Bulletin, 2021
Polyvinyl chloride (PVC) is the third one after polyethylene and polypropylene in the production demand. It intends to grow further, causing an increase in the risk of health and ecological problems due to environmental accumulation and incineration. In the present study, we determined the biodegradative abilities of marine bacteria for PVC.

Flex‐resistant permeable PVC films

Journal of Applied Polymer Science, 1977
AbstractMicroporous poly(vinyl chloride) films with flex resistance in excess of 400,000 flexes at 20°C and 65% R.H. and in excess of 30,000 flexes at −;15°C, and water vapor permeability in excess of 250 g/m2 24 hr have been prepared from controlled expansion and curing of plastisols, which contain a poly(vinyl chloride) (PVC) resin with a K value of ...

Kinetics of growth of polyvinylchloride (PVC) films

Thin Solid Films, 1973
Polyvinylchloride (PVC) films have been grown by isothermal immersion of rocksalt, copper and glass substrates into dilute solutions of PVC in 80% benzene + 20% acetone (B+A) and cyclohexanone solvents. The dependence of the kinetics of growth of the films on the concentration and temperature of the solution and the nature of the solvent and substrate ...

Radiation grafting of MMA onto PVC films

Journal of Applied Polymer Science, 1990
AbstractAn approach to the problem of producing poly(vinyl chloride) (PVC) graft copolymer exhibiting good mechanical properties and electrical resistance that suits its uses as an electrical insulator has been investigated. Graft copolymerization of methyl methacrylate (MMA) onto PVC using γ‐radiation as initiator has been studied.

Surface analysis of poor printability PVC films

Journal of Vinyl and Additive Technology, 1999
Abstract Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and X‐ray photoelectron spectroscopy (XPS) were employed to analyze the surfaces of PVC films with poor printability. FTIR indicated that, independent of formulation, the migrating species were metal carboxylates. Different techniques penetrate

Improved piezoelectricity in solvent-cast PVC films

IEEE Transactions on Dielectrics and Electrical Insulation, 1995
The piezoelectric coefficient of solvent cast polyvinyl chloride (PVC) films processed under simultaneous stretching and corona poling (SSCP) conditions has been enhanced by - 4x (d31 - 5.3 + 0.35 pC/N) as compared to the maximum value (0.5 to 1.3 pC/N) reported in the literature [l, 51.
