“…Figures and indicate the characteristic absorptional bands of the imide structures on the cotton and PET fabrics at 1777.60–1718 cm −1 (CO conjugate anhydride asymmetrical and symmetrical stretching), 1365 cm −1 (1376 cm −1 for PET) (CN aromatic amine stretching), 1091 cm −1 (CO stretching), 821 cm −1 (trisubstituted CC bending), and 724 cm −1 (CO bending). Also the intensity of OH stretching bands decreased due to the reaction of COOH groups into imide structure at the imidization process (see Figures 4 and 5) …”

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.

“…Various volume contents of carbon spheres were introduced into PI composites, 0.7 wt% PI/carbon sphere composites under seawater lubrication indicated the lowest coefficient of friction. Wear rate was also conducted under different lubricating conditions, where seawater lubrication conditions exhibited worse than other conditions due to its microstructure defects [74]. Qi et al studied the effects of seawater lubrication on the tribological properties of PI composites containing SCF and PTFE.…”
