    Notes: The effects of sulfur atoms on the thermal degradation and flammability of cellulose phenylthiophosphonate were investigated using thermogravimetry, IR spectrometry, and limiting oxygen index flammability tester. Introduction of sulfur atoms instead of oxygen atoms in the phosphonyl groups had little influence on the thermal degradation of cellulose. The thermal reactions were altered by ion exchange with sodium ions, and degradation of the cellulose chains was retarded. Cellulose phenylthiophosphonate was self-extinguishing above 4.64% phosphorus content. The flame-retardant properties remained when the cellulose phosphorus ester was ion exchanged with sodium ions. It was concluded that introduction of sulfur atoms into phosphorus esters of cellulose was effective in preventing the decrease in flame-retardant properties by ion exchange in laundering.

    Notes: Polymers including polyethylene, polycarbonate, and polytetrafluoroethylene were modified by glow discharge polymerization to enhance surface hardness. The surface hardness of the polymer substrates could be improved by glow discharge polymerizations of silicon-containing compounds. The mixture of tetramethylsilane (TMS) and oxygen was more effective than tetramethoxysilane to improve the surface hardness. The surface hardness improved by the glow discharge polymerization strongly depended on the nature of the polymer substrates to be modified. The adhesion between polymer films prepared from the TMS/O2 mixture by glow discharge polymerization and the polymer substrates was good.

    Notes: Glow discharge polymerizations of tetramethoxysilane (TMOS), tetramethylsilane/oxygen mixture (½ molar ratio) (TMS/O2), hexamethyldisiloxane (HMDSO), and tetramethyldisiloxane (TMDSO) were carried out for the preparation of thin, polymeric films with siloxane structures. The chemical composition of the formed polymers was examined by elemental analysis, infrared spectroscopy, and electron spectroscopy for chemical analysis (ESCA) in connection with polymerization conditions, especially, a level of the radiofrequency (rf) input power per mass of the monomers (W/FM value). The polymers prepared from HMDSO at fairly low W/FM values resembled in chemical composition the conventionally polymerized polydimethylsiloxane. The surface properties of the formed polymers also were evaluated by the measurement of surface energy.

    Notes: Glow discharge polymerizations of tetramethylsilane (TMS) were performed by the capacitive coupling of a 20 kHz frequency in comparison with those by the inductive coupling of a 13.56 MHz frequency. The polymers prepared by the former coupling were poorer in carbon and hydrogen, but richer in silicon than those prepared by the latter coupling. These two polymers showing similar infrared spectra contained CH3, CH2, CH, Si—O—C, Si—O—Si, Si—CH3, and Si—CH2—CH2—Si groups. Some physical properties involving surface energy, thermal stability, and absorption spectra in the regions of the UV and visible light were determined. This coating procedure was applied for surface hardening of a polyethylene sheet. The surface hardness of the polyethylene sheet was enhanced by a coating of plasma films prepared from TMS or the TMS/O2 mixtures. Surface hardness was determined by the pencil method and hardness was enhanced from 2B to 2H. The adhesion between these plasma films and polyethylene sheet was good even when immersed in 0.9% NaCl solution at 40°C for 10 days.

    Notes: Plasma polymerization of nitroethane provided highly wettable films whose surface energy was 66 × 10-3 N/m. The contact angle of water was 7 ± 2° at 20°C in air. This high wettability was maintained for a long duration of at least 2 months. Infrared and ESCA spectra showed that the plasma polymers contained no nitro groups and were composed of dehydrogenated carbon chains with a large amount of amido groups. The amido groups whose concentration reaches approximately 40% of the total carbon units may contribute to the high wettability.

    Notes: Comparative studies on plasma polymerizations of phenylsilane (PhSiH3) and toluene (PhCH3) have been carried out to prepare plasma polymers containing aromatic groups. The IR and ESCA spectra show that PhSiH3 and PhCH3 are subjected to ring-opening reactions in a discharge state to form polymers involving alkyl chains as well as aromatic groups. The ring-opening reactions are more feeble in the PhSiH3 system than in the PhCH3 system, which may be due to stabilization of phenyl-Si bonds in PhSiH3 by contribution of pπ-dπ bonding. Aromatic groups incorporated into the plasma polymers from PhSiH3 are mono-substituted.

    Notes: Plasma-polymerizations of perfluoromethylcyclohexane (PFMCH)/methane (CH4) mixture were investigated by elemental analysis, infrared spectroscopy, and ESCA; and gas transport characteristics of the plasma-films formed were studied. The addition of CH4 molecules to PFMCH accelerated defluorination to form plasma-polymers poor in fluorocarbon units. The surface energy of the plasma-polymers increased with increasing the CH4 concentration. The oxygen and nitrogen permeation coefficients (PO2 and PN2) and the PO2/PN2 ratio for the polymer films formed from the PFMCH/CH4 mixture depended on the CH4 concentration. The small CH4 addition was effective in improvement of the PO2 value and of the PO2/PN2 ratio, but the much addition was ineffective. The oxygen transport through the plasma-polymers was discussed.

    Notes: Kapton films were treated with seven plasmas: Ar-, N2-, O2-, CO-, CO2-, NO-, and NO2- plasmas. Surface properties and chemical composition of the plasma-treated Kapton films were investigated from the contact angle measurement, and the IR and XPS spectra. The plasmas, especially NO- and NO2-plasma, made the Kapton film surface hydrophilic. The XPS and IR spectra showed that the plasma led to the modification of the imide groups in the Kapton film to secondary amide and carboxylate groups.

    Notes: To obtain thin films containing carboxylate anions, hydrolysis of amido groups in films plasma-polymerized from trimethylsilyldimethylamine (TMSDMA) and bis(dimethylamino)methylvinylsilane (BDMAMVS) has been investigated by infrared spectroscopy and ESCA. The thin films from TMSDMA and BDMAMVS were hydrolyzed at 80-100°C for 3-16 h to transform amido groups to carboxyl groups. The products hydrolyzed from the TMSDMA-plasma-polymers were mixtures of carboxylate ester and carboxylic acid, and that from the BDMAMVS-plasma-polymers was carboxylic acid. The hydrolysis reaction was restricted at regions near polymer surfaces.

    Notes: Modification of plasma-polymers prepared from phenylsilane with sulfur trioxide was investigated by FT/IR spectroscopy and ESCA. The sulfonation of phenyl groups in the plasma-polymers occurred rapidly within 1 min when exposed to SO3 gas. The S/C and O/C atomic ratios determined by ESCA for the modified polymers were 0.138 and 0.418, respectively. The sulfonation made the plasma-polymers electrically conductive. The conductivity was sensitive to moist atmosphere. The logarithm of the impedance at 120 Hz decreased linearly with increasing the relative humidity. The plasma-films containing sulfonate groups may be a new material for moisture sensor devices.
