Quantitative characterization of plasma-polymer films, especially of ultrathin fluorinated carbon plasma polymer films, has been performed by ToF-SIMS to study changes in the surface composition and molecular distribution. CFX films on silicon and polyethylene terephthalate (PET) substrates were exposed to a pulsed Ar/CHF3 plasma by varying the deposition time from 10-90 s.111-113 The results show differences in film growth and CFX cross linking for the silicon and PET substrates.111...

LB coatings have been used as photoresists. In the area of ultrathin (single molecule) photoresists, spin-coated polymers tend to lack the consistency in structure and thickness necessary for these applications. However, preformed polymer LB films or polymerized monomeric LB films are extremely uniform, and can be used in these apphcations. Photo-cross-linking of poly(p-phenylene) and photopolymerization of ft>-tricosenoic acid and methacrylic acid LB films have been investigated (20,21). Etching resulted in patterns that had resolutions of ca 60 nm. (see Lithographic Resists)... 

An important staining technique was developed by Kanig [246] for the enhanced contrast of PE, a material that has been a model compound for fundamental polymer studies. Polyethylene crystals cannot be sectioned, nor are they stable in the electron beam, due to radiation damage. The chlorosulfonation procedure cross links, stabilizes, and stains the amorphous material in crystalline polyolefins, permitting ultrathin sectioning and stable EM observation. Chlorosulfonic acid diffuses selectively into the amorphous material in the semicrystalline polymer, increasing the density of the amorphous zone compared with the crystalline material. The treatment stains the surfaces of the... 

Yung and co-workers demonstrated a TENC membrane as NF filters [91]. The investigated TFNC membranes contained an electrospun PES nanofibrous scaffold as the mid-layer, a PET nonwoven as the mechanical support, and an ultrathin highly cross-linked amine polymer layer, formed by interfacial polymerization, as the barrier layer. By optimizing the interfacial polymerization of top barrier...
