“…All then show an increase in the peak around 530.5 eV and one more peak in the range between 534.5 and 535.5 eV. On the CF-DS-OX sample, this last peak has higher intensity and may be correlated with the higher Si(-O)4 content in the Si2p line [3]. From this analysis we may infer that the oxidation states shown in the Si2p line also appear in the O1s line, even though…”

“…The plasma species such as the gamma-system of nitrogen monoxide (γ-NO) in the bands of 200-280 nm, the hydroxyl (OH) radical in the bands of 281-324 nm. [29] The N 2 species in the bands of 325-393 nm, the Ar II lines in the bands of 400-447 nm, the atomic hydroghen (H β ) in the band of 485 nm, Ar I lines in the bands of 512-960 nm, and the O I in the bands of 777 nm and 842 nm, [31,32] were detected, resepctively. The reactive species of N-containingγ-NO, and oxygencontaining such as hydorxyl radical (OHÁ) and O I, are generated in plasmas due to the Ar CAPPs species that react with the N 2 and O 2 gases of air residue in ambient.…”

Significantly enhanced adhesion of polytetrafluoroethylene (PTFE) films to graphene-filled polyimide (PI) adhesives by argon (Ar) cold atmospheric pressure plasmas (CAPPs) at the exposure durations of 72-96 s was undertaken. Poor adhesion of PTFE film to PI adhesive with no bonding (100% delamination) was highly improved to good bonding (100% attachment) for PTFE film treated by Ar CAPPs. Hydrophobic PTFE surface (water contact angle up to 91.1 ) was changed to hydrophilic PTFE surfaces (water contact angle up to 37.4 -66.0 ) with Ar CAPPs treatment by formation of polar chemical bonds such as C-O and C=O. To realize how the chemical bonds of C-O and C=O were produced onto the PTFE surface by Ar CAPPs, the plasma active species of Ar CAPPs were detected by optical emission spectroscopy.

“…TMDSO films are used in automotive, aerospace, and biomedical applications to act as barrier coatings and to resist scratching and crazing [ 6 ]. A number of studies have investigated the mechanical properties of HMDSO films [ 8 , 9 , 10 , 11 , 12 ], but significantly fewer have investigated TMDSO films [ 4 , 5 , 7 , 13 ]. Harder TMDSO films with higher Young’s moduli have been deposited with higher O 2 concentrations in the monomer feed because of the increase of Si-O-Si bonds within the film [ 4 , 5 , 7 ].…”

“…Harder TMDSO films with higher Young’s moduli have been deposited with higher O 2 concentrations in the monomer feed because of the increase of Si-O-Si bonds within the film [ 4 , 5 , 7 ]. Very few studies have quantified the mechanical properties of microwave (MW) TMDSO films deposited by PECVD [ 4 , 5 ], with others performing semi-quantitative hardness analyses via pencil hardness testing [ 7 , 13 ]. Even fewer studies have investigated the deposition of TMDSO films deposited via radio frequency (RF) PECVD [ 14 , 15 ], let alone the mechanical properties.…”

“…Our previous work has shown that the position of the sample within a plasma polymerisation chamber relative to the electrode/s is a controlling factor in the chemistry and stability of plasma polymer films [ 27 , 28 ]. TMDSO films have been applied to CF composites to improve scratch resistance [ 13 , 29 ], but a continuous, or roll-to-roll, plasma deposition process for coating CFs prior to integration within a matrix to form a composite has yet to be demonstrated.…”

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.
