“…Moreover, there is not a significant change in the electric response during light exposure, thus we conclude that the polymeric materials are not photoconductive. The electrical insulating properties, along with their resistance to high temperatures, suggests that these materials could be used as coatings for vessels involved in several industrial processes in a similar way to PPS …”

“…These properties are due to the high polarizability and high reactivity of sulfur atoms, as well as the flexibility of S–S and C–S bonds . Therefore, sulfur‐containing polymers have several industrial applications; for instance, poly(phenylene sulfide) (PPS), a polymer comprised of aromatic rings bonded by sulfur atoms, is considered a super engineering material that shows many of the properties mentioned above . However, high production costs represent an obstacle for the use of this material in a broad range of industries.…”

BACKGROUND: Cyclic aromatic disulfides (CAD) can be used as cross-linking agents or precursors for the synthesis of high temperature resistant polymers such as poly(phenylene disulfides) (PPD). Chemical synthesis of CAD relies on the use of corrosive agents, detrimental for the environment. This paper reports an environment friendly chemoenzymatic procedure to obtain PPD starting from simple aromatic dithiols. RESULTS:The enzymatic reaction was carried out in an aqueous mixture with acetonitrile as co-solvent, using 1,4-and 1,3-benzenedithiol as monomers and a fungal laccase (EC 1.10.3.2) as catalyst. The products obtained were identified as mainly cyclic aromatic disulfides. Thermal analysis suggested that the enzymatically-synthesized CAD display thermal stability and are amenable precursors of high molecular weight sulfur-containing polymers through solvent-free, melt ring opening polymerization (mROP). After mROP, polymeric molecules around 12.8 kDa were obtained and identified as PPD. The resultant PPD shows uniform size, resistance to temperatures up to 400 ∘ C and electrical insulating properties. CONCLUSION: Laccase-catalyzed synthesis of CAD represents a novel reaction, not previously described elsewhere for oxidoreductases. A 100% substrate conversion was achieved under mild reaction conditions and no over-oxidation of CAD was observed, representing an advantage over chemical synthesis. The CAD products precipitated completely from the reaction medium, thus simplifying the purification process.

“…Polyphenylene sulfide (PPS) is a kind of high-performance thermoplastic resin which is insoluble in any solvent at room temperature. PPS has special properties of strong acid resistance, heat resistance, solvent resistance, and flame retardance [20,21], and its fiber has wide application in industry, such as for environmental protection filter materials [22]. Mass production of PPS staple fibers is primarily done through meltblown spinning.…”

Electrospinning (e-spinning) is an emerging technique to prepare ultrafine fibers. Polyphenylene sulfide (PPS) is a high-performance resin which does not dissolve in any solvent at room temperature. Commercial PPS fibers are produced mainly by meltblown or spunbonded process to give fibers ~20 μm in diameter. In this research, an in-house designed melt electrospinning device was used to fabricate ultrafine PPS fibers, and the e-spinning operation conducted under inert gas to keep PPS fibers from oxidizing. Under the optimum e-spinning conditions (3 mm of nozzle diameter, 30 kV of electrostatic voltage, and 9.5 cm of tip-to-collector distance), the as-spun fibers were less than 8.0 μm in diameter. After characterization, the resultant PPS fibers showed uniform diameter and structural stability. Compared with commercial PPS staple fibers, the obtained fibers had a cold crystallization peak and 10 times higher storage modulus, thereby offering better tensile tenacity and more than 400% elongation at break.

“…First, of all, its high temperature and heat resistance; chemical resistance to acids, alkalis, and organic solvents; crack resistance; low water absorption; low creep; and excellent electrical characteristics should be noted [1,2]. Due to these features, materials based on PPS are widely used in electrical and electronics as well as in other industries [3,4,5].…”

Reversible and Irreversible Color Change during Photo and Thermal Degradation of PolyphenyleneSulfide Composite

et al. 2019

View full text Add to dashboard Cite

The effect of the light spectral composition and temperature on the change of color characteristics and reflection spectra during the irradiation of polyphenylene sulfide reinforced by short glass fibers in the SUNTEST apparatus was analyzed. The scales of reversible color change upon successive exposure to total radiation corresponding to the sunlight spectrum and to visible light wereevaluated and the possible mechanisms for the observed effects are discussed. The features of the color change upon visible light irradiation of previously thermally aged samples wereconsidered. Possible causes for deviation from the Arrhenius law during thermal aging of the composite are discussed. It wasdemonstrated that even with a significant change in color, the physicomechanical and electrotechnical characteristics of the composite only changedslightly or remained virtually at the same high level.
