“…In addition, the higher IR peak intensity at 1050 cm À 1 , which is because of the symmetric and asymmetric C¼ O stretch in polysaccharide-like substances [44], corroborated the higher polysaccharide abundance in the foulants of MBR-C. Notably, two IR peaks associated with bending (472 cm À 1 ) and stretching (796 cm À 1 ) vibrations of Si-O-Si [45,46] were detected in the foulants of MBR-C, implying that the grit could deposit on membranes as a result of either permeate drag or entrapment by the deposited sludge flocs. Previously, Wang et al reported that the foulants of a submerged MBR displayed a substantial portion of organic matter and contained inorganic matter such as Si, Mg and Ca [47].…”

“…The wide precursor selection range and the study of each layer individually might allow the structure and properties of the entire multilayer coating to be considerably modified. 158,159 The working pressure during the PECVD processes typically ranges from 1 to 1000 Pa and plays an important role in determining the final structure of the PPF. Its increase results in the reduction of the mean free path of electrons and active species in the plasma, stimulating more inelastic collisions.…”

Free-Radical-Induced Grafting from Plasma Polymer Surfaces

With the advances in science and engineering in the second part of the 20th century, emerging plasma-based technologies continuously find increasing applications in the domain of polymer chemistry, among others. Plasma technologies are predominantly used in two different ways: for the treatment of polymer substrates by a reactive or inert gas aiming at a specific surface functionalization or for the synthesis of a plasma polymer with a unique set of properties from an organic or mixed organic-inorganic precursor. Plasma polymer films (PPFs), often deposited by plasma-enhanced chemical vapor deposition (PECVD), currently attract a great deal of attention. Such films are widely used in various fields for the coating of solid substrates, including membranes, semiconductors, metals, textiles, and polymers, because of a combination of interesting properties such as excellent adhesion, highly cross-linked structures, and the possibility of tuning properties by simply varying the precursor and/or the synthesis parameters. Among the many appealing features of plasma-synthesized and -treated polymers, a highly reactive surface, rich in free radicals arising from deposition/treatment specifics, offers a particular advantage. When handled carefully, these reactive free radicals open doors to the controllable surface functionalization of materials without affecting their bulk properties. The goal of this review is to illustrate the increasing application of plasma-based technologies for tuning the surface properties of polymers, principally through free-radical chemistry.

“…In comparison to the RF TMDSO films, the higher oxygen concentrations in the MW TMDSO films produced C 1s spectra that enabled the fitting of three peaks to the data. Peak A represents the contributions from Si-C, C-C, and Si-H, with the Si-C peak situated at a lower energy than the C-C, C-H peak at approximately 283 eV [ 38 ]. Peak B, at approximately 285 eV, was assigned to the beta-shift of the hydrocarbon peak, possibly because of a chain structure such as C-C-O-Si-O in which the oxygen atoms cause a shift to higher binding energies.…”

Characterising a Custom-Built Radio Frequency PECVD Reactor to Vary the Mechanical Properties of TMDSO Films

et al. 2021

Plasma-polymerised tetramethyldisiloxane (TMDSO) films are frequently applied as coatings for their abrasion resistance and barrier properties. By manipulating the deposition parameters, the chemical structure and thus mechanical properties of the films can also be controlled. These mechanical properties make them attractive as energy adsorbing layers for a range of applications, including carbon fibre composites. In this study, a new radio frequency (RF) plasma-enhanced chemical vapour deposition (PECVD) plasma reactor was designed with the capability to coat fibres with an energy adsorbing film. A key characterisation step for the system was establishing how the properties of the TMDSO films could be modified and compared with those deposited using a well-characterized microwave (MW) PECVD reactor. Film thickness and chemistry were determined with ellipsometry and X-ray photoelectron spectroscopy, respectively. The mechanical properties were investigated by nanoindentation and atomic force microscopy with peak-force quantitative nanomechanical mapping. The RF PECVD films had a greater range of Young’s modulus and hardness values than the MW PECVD films, with values as high as 56.4 GPa and 7.5 GPa, respectively. These results demonstrated the varied properties of TMDSO films that could in turn be deposited onto carbon fibres using a custom-built RF PECVD reactor.
