“…Lu et al 73 measured the Izod impact strength and crystallinity change of PPS and a series of PPS blends prepared using a twin-screw extruder. The components blended with the PPS included ethylene vinyl acetate (EVA), polyarylester (PAR), nanometer particles of SiO 2 , polypropylene (PP), and PP grafted with maleic anhydride (MAH) and with glycidyl methacrylate (GMA).…”

“…However, there is an approximately 40% amorphous fraction for PPS, which greatly affects its physical and mechanical properties. Thus, much effort has been put into improving the mechanical properties and impact strength . Lu et al , investigated the effect of heat treatment and incorporation of nanoparticles on the impact strength of PPS, and found that the Izod impact strength of the nanocomposites was greatly improved.…”

“…Thus, much effort has been put into improving the mechanical properties and impact strength . Lu et al , investigated the effect of heat treatment and incorporation of nanoparticles on the impact strength of PPS, and found that the Izod impact strength of the nanocomposites was greatly improved. Caminiti et al used DSC, Fourier transform infrared spectroscopy and energy‐dispersive XRD technologies to study T g of PPS and concluded that the onset of Δ c p should be taken as indicative of the range of molar masses between 600 and 50 000 g mol −1 and suggested that T g (α‐relaxation) of PPS decreases strongly for low molar masses.…”

The glass transition temperature (Tg) of poly(phenylene sulfide) (PPS) with various crystalline fractions has been studied using dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC). The DSC measurements show that Tg can be observed from the heating curves for the PPS sample with very low crystallinity, and no Tg is observed when the crystallinity is over 8%. DMA indicates that crystallinity has an important effect on molecular chain segment motion of PPS. When the crystallinity, Xc, of PPS is over 38%, there is only one chain segment motion, which mainly results from the crystalline chain vibration; while three different chain segment motions occur for PPS samples with lower crystallinity (Xc < 26%), which are amorphous chain segment motion, crystalline chain segment motion and constrained amorphous chain segment motion. Tg of PPS is mainly caused by the amorphous chain segment motion which is independent of the crystallinity, while the relaxation temperature corresponding to crystalline chain motion shifts to lower temperature as the crystallinity increases. The reduction of the relaxation temperature can be attributed to the disorder‐order transition of amorphous chains for PPS with lower crystallinity. © 2012 Society of Chemical Industry

“…To overcome those deficiencies, considerable research effort has been dedicated to PPS‐matrix composites. Modification of PPS with nanoparticles,8–16 nanoclay,17–19 and nanotubes20–24 have undergone rapid development in recent years and showed remarkable reinforcing effects on the mechanical, thermal, and wear properties.…”

Polyphenylene sulphide (PPS)/multi-walled carbon nanotube (MWCNT) composites were prepared using a melt-blending procedure combining twin-screw extrusion with centrifugal premixing. A homogeneous dispersion of MWCNTs throughout the matrix was revealed by scanning electron microscopy for the nanocomposites with MWCNT contents ranging from 0.5 to 8.0 wt%. The mechanical properties of PPS were markedly enhanced by the incorporation of MWCNTs. Halpin-Tsai equations, modified with an efficiency factor, were used to model the elastic properties of the nanocomposites. The calculated modulus showed good agreement with the experimental data. The presence of the MWCNTs exhibited both promotion and retardation effects on the crystallization of PPS. The competition between these two effects results in an unusual change of the degree of crystallinity with increasing MWCNT content.
