“…In addition, some ame retardant elements, such as P, can also be introduced in the backbone of the polymer to increase the thermal stability and char formation. 72,73 The functionality of the polyol and isocyanate are important factors determining the thermal degradation behaviour of PU. They can determine the crosslinking density of PU and char formation.…”

“…While PAA showed three steps weight loss behavior that was as 10% until 164 °C, 40% until 560 °C and 65% until 800 °C, PI has shown one degradation step starting at about 560 °C and weight loss 40%. This result indicates that the PI structure is very stable until 560°C and has very high char amount …”

“…Third loss step (about 15%, 580 °C) belongs to the degradation of PI coating on the fabrics. The residue amounts (16.7% for cotton, 23.5% for polyester) of coated fabrics were higher than noncoated fabrics, which was an expected result due to the high char amount of the PI polymer (approximately %57) …”

Multifunctional technical textiles are of great interest both by industry and academia and these products are considered as high value-added products that contribute to the economies of countries. In this study, polyamic acid (PAA) was synthesized through polycondensation of pyromellitic dianhydride (PMDA) and 4,4 0 -oxydianiline (ODA) in dimethyl acetamide (DMAc) at low temperature. Then, PAA was coated onto woven cotton and polyester fabric by padding technique. Finally, polyimide (PI)-coated multifunctional cotton and polyester fabrics were obtained by an easy coating technique and low-temperature imidization. Thus, low cost, easily accessible and widely used cotton and polyester fabrics were converted to high-performance textile products, which are flame retardant, UV protective, acid resistant, and waterproof. The chemical, thermal, morphological, optical, mechanical, wettability, chemical resistance, and flame retardancy properties of developed fabrics were investigated. Optical results showed that both PI-coated cotton and polyester fabrics are UV-A protective compared to noncoated fabrics. Moreover, PI-coated samples have high contact angles which are 111.43 and 113.40 for PI-coated cotton (PI-c-C) and PI-coated polyester (PI-c-PET), respectively. Young's modulus of PI-c-PET fabrics increased four times more than noncoated polyester fabric. PI coating changed the burning behavior of both cotton and polyester fabrics in a positive way. All the test results showed that these developed multifunctional textile products might find an application in different industrial areas such as automotive, aerospace, protective clothing, and so on due to easy and inexpensive production techniques and also superior properties.

“…Polyimide (PI), a type of heterocyclic polymer containing an imide ring on the main chain, has been widely used in various fields, such as in high‐temperature dust filtration, protective fabrics, industrial fire‐retardant and insulation materials, and functional composite materials, because of its attractive chemical and mechanical properties, including its excellent resistance to high and low temperatures, high strength and modulus, high electrical insulation, and corrosion resistance. The specific imide structure in the molecular chain of PI results in a smooth fiber surface and a low surface energy; thus, it possesses strong chemical inertness and excellent fiber properties .…”

In this study, the effects of mixed-acid oxidation on the contents of surface elements, morphology, fiber fineness, mechanical properties, mass change rate, chemical structure, and microaggregate structure of dry-spun Suplon polyimide (PI) fibers were systematically investigated with wet chemical treatment with HNO 3 /H 2 SO 4 . Experiments investigating both the improvement in the O/C ratio of the fiber surface elements and the changes in other performance features were conducted through the functional modification of the fibers. Meanwhile, the causes of specific changes in the mechanical properties of the oxidized PI-fiber-reinforced polypropylene-resin-based composites were studied and are discussed. The results of this study demonstrate that the treatment of the fibers with HNO 3 /H 2 SO 4 mixed-acid oxidation resulted in significant changes in the properties of the fibers; these changes included an uneven surface, increased specific surface area and surface roughness, a locally etched surface, increased surface energy and O/C ratio, an enhanced wettability, an increased fiber fineness, reduced mechanical properties, and a mass gain in the fibers. Although the chemical structures of the fibers treated by oxidized HNO 3 /H 2 SO 4 were not significantly changed compared to those of the untreated fibers, the microscopic aggregation of the treated fibers changed to some degree, and the ratio of the amorphous regions significantly increased. Taken together, the functional modification of the PI fiber surface was achieved efficiently through the use of a suitable HNO 3 /H 2 SO 4 oxidation process and with other performance features of the fibers taken into account. This was favorable for the enhancement of the interfacial properties of the polypropylene fibers and the matrix resins, and thus, the modification improved the mechanical properties of the composites.
