Development of amorphous carbon protective coatings on poly(vinyl)chloride

Recent Progress in Surface Modification of Polyvinyl Chloride

“…The major research in this field has been conducted on the influence of plasma treatment under different working environments on PVC surface chemistry [43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66]. This may be because of the solvent-free basis of the method which is of importance from an environmental viewpoint.…”

“…It was seen that treating PVC surface in plasma led to the C–C, C–Cl, and C–H bonds scission since the induced energy exceeded the bonds dissociation energy [43,44,45,46,47,48,49,50,51,52,53]. Plasma exposure in an inert gas gave rise to the generation of metastable species, that is, carbon radicals (Figure 1) on PVC surfaces which could either form a crosslinked network or be oxidized to give new functionalities, in case the treated surface was exposed to air [43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58]. Provided oxygen or air was operated as the working gas, carbonyl, carboxyl, peroxide, and ester groups were most probable to form [59].…”

Elastic Modulus and Hardness of Plasma‐Polymerized Organosilicones Evaluated by Nanoindentation Techniques

“…This is because CC sp 2 clusters are formed in carbon network (graphite‐like a‐C:H films). The PECVD technique can be used to deposit a‐C:H films with a low hardness of about 0.5 GPa, using hydrocarbon (benzene, acetylene) as a pure precursor or in mixture with argon gas . Similar properties are possessed by a‐CO:H films prepared at different powers (10–300 W) from mono‐terpene alcohol or ethyl lactate precursor .…”

Data on Specific Polymers

“…1067 Hydrogenated amorphous carbon films were deposited onto commercial PVC plates from acetylene and argon plasmas excited by radiofrequency. 1068 At lower argon concentrations, hardness, wear and oxidation resistances were improved as compared with the uncoated PVC. 1068 ZnO and CaCO 3 nanoparticles were incorporated into PVC.…”

“…1068 At lower argon concentrations, hardness, wear and oxidation resistances were improved as compared with the uncoated PVC. 1068 ZnO and CaCO 3 nanoparticles were incorporated into PVC. 1069 Photoxidative degradation of these composites at 365 nm were compared.…”
