Preparation of SiO₂/PPS Fiber and Study of its Heat-Resistant Properties

Abstract

Through the addition of nano-silicon dioxide in the pure polyphenylene sulfide, the masterbatches were obtained, then using melt spinning technology to prepare SiO2/PPS fiber. The structure and heat-resistant properties of samples were characterized by transmission election microscopy (TEM), infrared spectrum (IR), differential scanning calorimeter (DSC) and other measurements. The experiment results indicate that the mechanical and heat resistance properties of PPS fiber were improved after adding the content of 1%wt nano-silicon dioxide. When the fiber was heated at 230°C for 24 hours, the breaking strength and elongation increased by 2.412cN/dtex and 11.90% compared to the pure PPS fiber. Moreover, the working temperature raised by 50°C.

Enhanced Oxidation Resistance of Polyphenylene Sulfide Composites Based on Montmorillonite Modified by Benzimidazolium Salt

“…Therefore, research about improving the oxidation resistance of PPS has been reported over the last few decades [7,8,9]. Thus far, the methods of antioxidant modification can be mainly divided into two categories: (1) the surface coating method and (2) the direct addition of nanoparticles or antioxidants [6,8,9,10,11,12,13].…”

“…Various nanoparticles such as silicon carbide (SiC), silicon dioxide (SiO 2 ), montmorillonite (MMT), carbon black, etc. [11,13,14], have been directly added into PPS resin to improve the oxidation resistance. Sugama [9] used octadecylamine as a pretreatment agent to modify montmorillonite (MMT).…”

Preparation and characterization of polyphenylene sulfide nanocomposites

“…This discrepancy could be related to the different processing method and thermal history of the nanocomposites, which have a strong effect on the final composite properties. On the other hand, very slight s y rises or even some decrements at high loadings have been reported for nanocomposites filled with SiO 2 (Yang et al, 2013;Sheng et al, 2011) (see Table 7.2), attributed to nanoparticle agglomeration.

Enhanced mechanical, tribological, and acoustical behavior of polyphenylene sulfide composites reinforced with zero‐dimensional alumina

“…15 One way to improve the thermal stability and mechanical properties of the PPS polymer is by increasing the specific stiffness and strength of the material by the addition of reinforcing fillers. Examples of reinforcing fillers that have been reported till date include carbon fiber, 16,17 titanium dioxide, 18 silicon dioxide, 19,20 nano copper oxide, 21 hexagonal boron nitride, 22,23 carbon nanotubes, 24 and graphite. 25 Another potential filler in PPS composite that has been least explored in literature is alumina.…”
