It was found that inclusion of 0.3 g/l AlCl3,6H2O as a feed additive in hyperfiltration tests was sufficient to stabilise a porous glass membrane (batch A-1) with relatively high volume flux and modest solute rejection characteristics. One-tenth of t

It is well known that the rate of plasma polymerization, or deposition rate, of a given monomer depends on various plasma process parameters, e.g., monomer flow rate, pressure, power, frequency (DC, rf or microwave), location of the substrate in the

The plasma homo- and copolymerizations of tetrafluoroethylene (TFE) and chlorotrifluoroethylene (CTFE) in a capacitively coupled tubular reactor (TR) with external electrodes were studied by means of microgravimetry and FT-IR and XPS analyses. The de

Plasma polymerized vinyltrimethoxy silane films were deposited on transparent polycarbonate substrates. The adherent, clear films protected the substrates from abrasion and also served as antireflection coatings. Posttreatment of the vinyltrimethoxy

The technique of plasma polymerization under vacuum conditions at ~0.1 Torr has been employed to produce highly moisture resistant, thin polymer films on hygroscopic alkali metal halide crystal materials. The polymer film is fluorocarbon in nature. I

An IR and XPS study of the low-pressure, radiofrequency, glow-discharge plasma copolymerization of ethylene (ET) and tetrafluoroethylene (TFE) is presented. The potential for creating Tefzel- or Teflon-like coatings on various polymeric substrates fo

The ESCA spectra and data obtained by Morra et al. (1989) on poly(tetrafluoroethylene) (PTFE) exposed to atomic oxygen plasma are closely reexamined. It is shown that the spikes observed in Morra et al. plots of O/C or F/C versus time of the exposure
