Abstract The aim of this study is to form the sulfur defects on monolayer molybdenum disulfide (MoS2) by low temperature microwave plasma treatment suppressing disturbance of molecular structure. CVD-grown and plasma treated multilayer MoS2 surface were analyzed to investigate the effects of H2 and Ar plasma treatment on sulfur defects and molecular structure. It was found that the disturbance of molecular structure was suppressed in the H2 plasma treatment compared to the Ar plasma treatment. Varying the incident ratio of hydrogen ions H+ and radicals H*, the influences of H2 plasma treatment with high and low H*/H+ ratio on monolayer MoS2 structure were discussed. As a result of X-ray photoelectron spectroscopy, Raman spectroscopy and photoluminescence analysis, sulfur defects increased with the increase in total amount of radical incident on MoS2. In addition, it is speculated that the etching with radical contributed to form sulfur defects suppressing the disturbance of molecular structure.

The performance of the polyphenylene sulfide fiber (PPS) was investigated by low temperature glow discharge plasma . The experimental results show that under the treatment of different plasma conditions, the PPS fiber surfaces appear the varying degree physics and chemical etching. It’s found that the friction coefficient and hydrophilicity of PPS fiber treated by low temperature plasma improve . X-ray photoelectron spectroscopy (XPS) analysis shows that the surface of PPS fiber produced etching, cross-linking, oxidation. Variations of tensile breaking strength of PPS with different parameters are analyzed.

And Performance

In this paper, the crystallinity, tensile strength and hydrophility of polytetrafluoroethylene (PTFE) filled with 7wt.% Y2O3-ZrO2 (YSZ) were studied using X-ray diffraction (XRD), mechanical property testing and low-temperature plasma. The results show that the crystallinity gradually increases while tensile strength decreases with the stretch ratio going up; with YSZ content increasing, the tensile strength increases while the crystallinity decreases.

With the increase in the environmental protection consciousness of people, attention has focused on plasma technology because of its efficiency and environmentally friendliness. In order to improve the dyeing behavior of wool fabrics, surface modification of wool fabrics was carried out using an atmospheric pressure (argon) low temperature plasma treatment (LTP). Morphology and chemical composition analyses of the treated wool fiber surface were carried out by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The effect on the surface properties of wool fabrics treated for different times was evaluated. The results showed that the coloration of wool fabric is improved with an argon atmospheric pressure low temperature plasma (LTP) treatment but the fabric has a lower color fastness to washing and rubbing. This results from the formation of sulfonic groups and the increase in nitrogen content attributed to more severe etching and oxidization on the surface of wool fibers.
