Plasma polymerization of phenylsilane

Abstract

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.

Heat-Induced Association and Dissociation Behavior of Amphiphilic Diblock Copolymers Synthesized via Reversible Addition−Fragmentation Chain Transfer Radical Polymerization

“…The number-average degrees of polymerization (DP n ) of the NaAMPS and NIPAM blocks are 61 and 34, respectively, calculated from GPC and 1 H NMR data listed in Table . On the basis of GPC and thin-layer chromatography (TLC) data, it was confirmed that no NIPAM homopolymer coexists with pNaAMPS−NIPAM. The GPC elution profile of pNaAMPS−NIPAM was unimodal with no indication of the presence of higher or lower molecular weight NIPAM homopolymer.…”

Plasma dye coating as straightforward and widely applicable procedure for dye immobilization on polymeric materials

“…A final deposition technique is plasma polymerization where a thin film is directly formed onto the substrate during exposure to plasma 59 , 60 . In this process, gaseous or pre-absorbed simple monomers are fragmented via inelastic collisions with the energetic plasma, which are consecutively recombined and bounded into a thin film formed on the material surface.…”

Methylhydrosilyl Chemostructural Effects in Polyhydrosilanes

“…A weak signal at the high BE side of the main peak (∼292 eV), is the shake up satellite due to the phenyl groups. 19 The Si 2p spectrum of b-PDPHS contains three components at BE's 99, 100, and 102.9 eV. The peak at 99 eV represents elemental Si and its intensity is about 32.5% of the total Si 2p signal.…”

“…In the case of the PDPHS structure the C 1s spectrum consists of two main components one at BE = 284.6 eV (C−C, CC, and C−H species) and one at 286.1 eV (C−O). A weak signal at the high BE side of the main peak (∼292 eV), is the shake up satellite due to the phenyl groups . The Si 2p spectrum of b-PDPHS contains three components at BE's 99, 100, and 102.9 eV.…”
