“…Plasma pretreatment may be performed prior to deposition of the PECVD coating; plasma pretreatment increases the surface energy of the substrate by eliminating organic contaminants. The adhesion of the coating to the substrate may be enhanced by plasma pretreatment [15]. During the PECVD deposition process, the bombardment of the substrate with energetic particles increases the adhesion of coating through energetic particle implantation and enhanced surface mobility [16].…”

“…The enhancement in sp 3 content with the addition of silicon also reduces the internal residual stress in the DLC coatings. Consequently, silicon incorporation increases the adhesion of the Si-DLC coating to the substrate [15]. Therefore, the downshift in the position of D and G peaks in Si-DLC films is partially attributed to the reduction in the internal compressive stress that is associated with the presence of the Raman spectroscopy is a powerful tool to understand carbon bonding in carboncontaining coating.…”

In this study, we describe reducing the moisture vapor transmission through a commercial polymer bag material using a silicon-incorporated diamond-like carbon (Si-DLC) coating that was deposited using plasma-enhanced chemical vapor deposition. The structure of the Si-DLC coating was analyzed using scanning electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, energy-dispersive X-ray spectroscopy, selective area electron diffraction, and electron energy loss spectroscopy. Moisture vapor transmission rate (MVTR) testing was used to understand the moisture transmission barrier properties of Si-DLC-coated polymer bag material; the MVTR values decreased from 10.10 g/m2 24 h for the as-received polymer bag material to 6.31 g/m2 24 h for the Si-DLC-coated polymer bag material. Water stability tests were conducted to understand the resistance of the Si-DLC coatings toward moisture; the results confirmed the stability of Si-DLC coatings in contact with water up to 100 °C for 4 h. A peel-off adhesion test using scotch tape indicated that the good adhesion of the Si-DLC film to the substrate was preserved in contact with water up to 100 °C for 4 h.

“…Despite all of its useful properties, PC always suffers from poor scratch resistance and vulnerability to the environmental damages. There are many efforts being done to increase its hardness and scratch resistance by applying sol-gel hard coatings [4][5][6][7][8], incorporating hard nanoparticles into the melt polymer [9], coatings applied by physical and chemical vapor deposition [3,10] and plasma enhanced chemical vapor deposition [11,12]. From cost and simplicity point of views, hard sol-gel coatings for improving PC properties is a very common method.…”

In the present work, a new aqueous sol–gel procedure has been used for producing hard transparent organic–inorganic nanohybrid coatings on polycarbonate (PC) substrate for improving its optical and mechanical properties. Sol-gel thins films were prepared by mixing Si and Al aqueous precursors and applied them on the cold plasma treated PC substrate. TEOS, GPTMS and aluminum tri sec-butoxide were used as main precursors. In order to improve the adhesion strength onto polymer, PC substrates were treated by Dielectric Barrier Discharge (DBD) system being conducted at atmosphere pressure in open air. The effects of sol ratios, curing temperature and aging time on the prepared coatings properties were investigated. Chemical, structural, morphological, optical and mechanical characteristics of the samples were studied by ATR-FTIR, EDS, XRD, FE-SEM, TEM, UV/vis spectroscopy, pencil hardness and eraser scratch methods. The obtained results indicated that the water contact angle of PC (73.24°) decreased to 6.32° by 45 second plasma treatment due to added functional groups on the treated surfaces. All of the films showed higher optical transmittance (89%) than the raw PC (86%) that was stemmed from the lower refractive index of the prepared films. Films indicated good adhesion onto the plasma treated substrates (5B). The pencil hardness of the PC substrate (4B) improved to 3H (8 pencil grade increment) with just a single layer coating (about 200 nm thickness) due to the preparation of new hard structures of interlocked Si and Al atoms.

This study examined the surface morphological evolution of polycarbonate and acrylonitrile butadiene styrene (PC/ABS) irradiated with an Ar ion beam using an ion beam system. PC was not affected by the Ar ion beam treatment at a lower ion beam treatment times but the ABS portion formed a foam-like nanostructure at the surface. On the other hand, both PC and ABS formed nanostructures with length of 100 to 120 nm and a mean diameter of %35 nm at longer beam treatment times. The Raman and FTIR spectra revealed polymer chain scissioning. Nanoindentation showed that the hardness and elastic modulus of the PC/ABS decreases from 0.22 to 0.18 GPa and from 3.39 to 2.98 GPa, respectively with increasing Ar ion beam treatment time due to the surface nano-structures formed by Ar ion beam.
