Air Plasma Treatment

Different time air plasma treatment was conducted on acrylonitrile–butadiene rubber (NBR) surface, the wettability and friction behavior of the samples surface were measured after two months of storage. The changes in surface composition and microstructure during storage process were observed by X-ray photoelectron spectroscopy (XPS) and atomic force microscope (AFM), respectively. The results show that the wettability of modified surface has obvious “hydrophobic recovery” phenomenon in the storage process, and the range of contact angle increase is closely related to the plasma treatment time, mainly because the change in surface composition at various time treatment are different during storage; the frictional behavior of plasma-modified NBR surface has not exhibited a “recovery” phenomenon after two months of storage, and the friction coefficient of the surface treated for 4 min and 8 min were even smaller than those before storage, which is due to the smoother and lower roughness of the surface morphology after storage. This study demonstrates that air plasma treatment is a promising technique for improving the wettability and tribological properties of NBR rubber, but the proper treatment time is needed to make the surface have the best wetting and frictional behavior.

Different treatment time and bias voltage with RF Ar plasma were used to improve tribological properties of NBR (Nitrile Butadiene Rubber). Chemical structure analyses of NBR by Attenuated Total Reflectance (ATR) were performed to clarify the functionality modification after the plasma treatment. In addition, wetting experiments were carried out by measuring the contact angle of distilled water drops on the NBR surface. ATR analysis revealed that the number of - C = O , - C - O , O - H functional groups increased after the argon plasma treatment. The functional groups led to changes in the contact angle from 100 to 50 degrees. The results showed that form-like nanostructures on the NBR was observed at the bias voltage of -400 V. The friction test showed that coefficient of friction after modified NBR in lubricated condition decreased from 0.25 to 0.15 with the increasing bias voltage due to the surface structure formations and better bonding with grease lubricant.

Morphology And Mechanical Properties

The effects of the montmorillonite clay surface modified with 25-30 wt% of methyl dihydroxyethyl hydrogenated tallow ammonium (Clay-MHA) on morphology and mechanical properties of poly(lactic acid) (PLA)/acrylonitrile-butadiene rubber copolymer (NBR)/Clay-MHA composites were investigated. The composites of blends of PLA/NBR with Clay-MHA were prepared by melt mixing in an internal mixer and molded by compression molding. The ratio of PLA and NBR was 80/20 by weight and the Clay-MHA content was 1, 3, 5 and 7 phr. The results showed Young’s modulus and stress at break of the composites increased with increasing Clay-MHA content. While the tensile strength and strain at break of the composites decreased with increasing Clay-MHA content. Scanning electron microscopy analysis showed that the addition of Clay-MHA could improve the miscibility of PLA and NBR to be homogeneous blends and the pore in polymer blends was disappeared.

Purpose – The purpose of this paper is to study the possibility and validity of using radio frequency (RF) power argon (AR) ion plasma treatment to modify the surface of nitrile butadiene rubber (NBR) and the change in the chemical structure under various bias voltage. Using wear test, the authors also compared the friction and wear properties of untreated and treated NBR. Design/methodology/approach – The hybrid RF-power sputtering system was used to generate RF Ar plasma to modify the surface of NBR specimens. The tribological properties were evaluated by ball-on-disc test using a load cell mounted on the ball holder. Findings – It was found that the NBR surface treated by the Ar plasma improved the wettability, friction and wear performance than the untreated NBR. The ATR-IR analysis indicated that the improvement come from the oxygen based functional groups generated on the surface of NBR. The improvement of friction and wear resistance may also come from the formation of nanostructure surface. Originality/value – In this study, the authors develop the RF AR ion plasma treatment at different bias voltage, and it has been used to modify the surface of NBR to increase the tribological performance.

The effects of the montmorillonite clay surface modified with 0.5-5 wt% aminopropyltriethoxysilane and 15-35 wt% octadecylamine (Clay-ASO) and polyethylene-g-maleic anhydride (PE-g-MA) on morphology and mechanical properties of poly (lactic acid) (PLA)/acrylonitrile-butadiene rubber copolymer (NBR) blends were investigated and compared. The PLA/NBR blends and composites were prepared by melt mixing in an internal mixer and molded by compression molding. The ratio of PLA and NBR was 80/20 by weight and the Clay-ASO and PE-g-MA contents were 3, 5 and 7 phr. The morphology analysis showed that the addition of Clay-ASO and PE-g-MA at high content could improve the miscibility of PLA and NBR to be homogeneous blends due to the voids in the polymer matrix were decreased. The tensile properties showed Young’s modulus of the PLA/NBR/Clay-ASO composites was more than that of the PLA/NBR blends and Young’s modulus of composites increased with increasing Clay-ASO content, while the tensile strength and strain at break decreased with increasing Clay-ASO content. The incorporation of PE-g-MA 3 phr could improve the tensile strength, stress at break and strain at break of PLA/NBR blends.
