“…Plasma treatment not only induces physical and chemical changes in the polymer surface but also keeps the original qualities of polymer to the greatest extent, such as its mechanical properties. Based on previous studies, various organic functional groups can be formed on the polymer surface with the plasma technique and by using different carrier gases, including O 2 , 11-13 N 2 , 14 He, 15 Ar, 12,13 NH 3 16,17 and H 2 14 etc. In the study done by Lien, 15 He and Ar plasmas were used to modify the polytetrafluoroethylene (PTFE) surface.…”

In this research study, air plasma-treated polyphenylene sulfide film was used to prepare polyphenylene sulfide/glass fiber cloth composites for improving interfacial adhesion and mechanical properties. The effect of air plasma treatment on the properties of polyphenylene sulfide films was investigated by X-ray photoelectron spectroscopy and water contact angle analysis. According to the X-ray photoelectron spectroscopy analysis, it was found that plasma treatment led to the emergence of oxygen-containing polar groups on the film surface. The intensity of sulfide oxides (S = O and O = S = O) on the surface of polyphenylene sulfide films increased to 79.03% after it was modified by air plasma. Water droplet contact angle analysis indicated that plasma treatment significantly increased the hydrophilicity of the polyphenylene sulfide film. The contact angle was 38 degrees for plasma-treated polyphenylene sulfide film, compared to 78.5 degrees for untreated polyphenylene sulfide film. Tensile strength and notched impact strength of plasma-treated polyphenylene sulfide/glass fiber cloth (50/50) composite increased by 11% (from 248.49 MPa to 275.70 MPa) and 18% (from 52.26 KJ/m2 to 61.43 KJ/m2), respectively, compared with the raw specimen, which was consistent with the morphology analysis result. Meanwhile, the mechanical properties of the composites were improved with the increased discharge power density and treatment time.

“…It is well known that -OH and other polar groups exist on the surface of GF. [13][14][15] With the presence of -SO 2 -, PASS is more preferential to form hydrogen bonds with GF than pure PPS. In addition, compared with the pure PPS (nonpolar), -SO 2 -can increase the polarity of matrix, which will improve the van der Waals forces between the GF and the matrix.…”

In this article, polyphenylene sulfide (PPS)/polyarylene sulfide sulfone (PASS) was melt blended and PPS/PASS/glass fiber cloth (GFC) composite was prepared. Mechanical testing and dynamic mechanical analysis DMAof PPS/PASS blends and PPS/PASS/GFC composites were performed to inspect the effects of PASS on the mechanical properties of the composites. With the presence of PASS, the strength and modulus of the PPS/PASS blends declined to some extent, while the strength and modulus of the PPS/PASS/GFC composites increased. The results indicate that the addition of PASS is beneficial for strengthening the interaction between PPS and GFC. The scanning electron microscopy results of the impact fracture surfaces of composites were also consistent with the data of mechanical properties.

“…However, its applications are hampered in many cases for its low creep resistance, poor abrasion resistance and high linear coefficient of thermal expansion [1][2][3][4][5]. Much work has been done for the modification of PTFE [6,7], especially modified by fillers [8][9][10][11]. SiO 2 is one of the most commonly used inorganic fillers, in addition to improve the creep resistance and wear resistance of PTFE, it is cheap and widely existed.…”

In this paper, PTFE (polytetrafluoroethylene)/ SiO 2 organic-inorganic hybrids were prepared with PTFE emulsion and tetraethoxysilanes (TEOS) through in-situ Sol-gel process, and then modified by PTFE grafted polymer. The studies included Sol-gel manufacturing process, the effects of SiO 2 content and graft polymer on the properties of the hybrids. The result showed that, cosolvent ethanol was not needed during the process of Sol-gel because it could make PTFE emulsion colloidal particles agglomerated. When the mass fraction of SiO 2 was 1.05 %, the tensile strength reached 20.96 MPa, which was nearly twice as much as that of the pure PTFE sample. Hybrids were treated by PTFE grafted glycidyl methacrylate (PTFE-g-GMA) and silane coupling agent KH-550, after which the tensile properties of hybrids were all enhanced. SEM (scanning electron microscope) images showed that SiO 2 changed the original fracture morphology of PTFE. The diameter of SiO 2 could reach 110 nm in the hybrid, and the size of SiO 2 was further refined by modification. Hybrids with different contents of SiO 2 were also analyzed with TGA (thermogravimetric analyzer), through which it could be found that decomposition temperature were improved with an increasing SiO 2 content. Furthermore, the crystallinity reached a maximum value 47.03 % measured by DSC (different scanning calorimetry) when the SiO 2 content was 2.55 %. Additionally, more SiO 2 could hinder the motion of chain segment and destroy the crystallization sequence length, so the crystallinity and crystallization velocity both decreased at the mass fraction of 7.37 %, but the crystallization behavior was enhanced after modification with graft polymer. It has been found that PTFE-g-GMA contributes to the compatibility between PTFE and SiO 2 .
