“…Moreover, it can be seen that several f-ZrP nanoplatelets are embedded on the fractured surface of the PA6 polymer. This could be attributed to the surface modification with poly(HCCP- co -bPEI) present on the surface of the ZrP and the decreased polarity. , Hence, the improved compatibility between the f-ZrP and PA6 polymer matrix results in a uniform dispersion, thereby increasing the mechanical and flammability properties of the PA6 composites.…”

To obtain polyamide 6 (PA6) composites with improved flame retardancy and thermomechanical properties, highly cross-linked supramolecular poly(cyclotriphosphazene)functionalized α-zirconium phosphate (f-ZrP) nanoplatelets were synthesized and melt-blended with PA6 in a twin-screw extruder. The performance enhancements of composites were investigated through measuring the dynamic mechanical property and observing cone calorimeter data, toxic gas evolution, and UL-94 rating. The thermomechanical performance of PA6 was increased by 37.2% after composite formation with f-ZrP. As for the fire retardancy performance, compared to neat PA6, the composite containing 10 wt % f-ZrP showed 41.7 and 30.4% decrease in the peak heat and total heat release rates, respectively, and the UL-94 rating of the composite was V-0. Moreover, the thermogravimetric analysis combined with infrared spectroscopy revealed that the addition of f-ZrP to the PA6 led to decrease in the evolution of the volatile compounds and toxic gases, with the formation of highly cross-linked P−N-containing dense char with microspheres, providing a strong barrier to the inhibition of the heat and flammable volatile components transferring between the flame zone area and substrate during the combustion test. Finally, based on the obtained results, the possible mechanisms for improved mechanical and fire retardancy properties of the composites were proposed.

“…In the spectrum of the pristine PA6 nanofibers, all of the absorption peaks were related to the characteristic absorptions of PA6. The absorption band at 3300 cm –1 was attributed to NH stretching, and the band corresponding to the CH stretching occurred at about 2930 cm –1 . Two main characteristic peaks at 1641 and 1543 cm –1 were assigned to C  O amide-I stretching and N–H amide II deformation of the PA6 molecular chain .…”

With the rapid development in wearable electronics, self-powered devices have recently attracted tremendous attention to overcome the restriction of conventional power sources. In this regard, a simple, scalable, and one-pot electrospinning fabrication technique was utilized to construct an all-fiber-structured triboelectric nanogenerator (TENG). Ethyl cellulose was co-electrospun with polyamide 6 to serve as the triboelectric positive material, and a kind of strongly electronegative conductive material of MXene sheet was innovatively incorporated into poly(vinylidene fluoride) nanofiber to act as a triboelectric negative material. The assembled all-fiber TENG exhibited excellent durability and stability, as well as excellent output performance, which reached a peak power density of 290 mW/m2 at a load resistance of 100 MΩ. More importantly, the TENG was capable of harvesting energy to power various light-emitting diodes (LEDs) and monitoring human movements as a self-powered sensor, providing a promising application prospect in wearable electronics.

“…The content of solid residues increased when the temperature was higher than 450 °C, which was similar to the results of the thermal properties analysis of other polyesters with sulfonic acid groups. [ 28 ] However, the content of catalyst TBT did not have a significant effect on the thermal stability of the polyester.…”

Waterborne sulfonate polyesters (WSPs) are prepared by esterification and condensation reaction using 1,4‐cyclohexadimethanol, diethylene glycol, and iso‐phthalic acid as monomers and 5‐sulfoisophthalic acid monosodium salt as hydrophilic monomers. The obtained WSPs are characterized with Fourier transform infrared spectroscopy, 1H NMR, differential scanning calorimetry, thermogravimetric analysis, dynamic light scattering, and water contact angle is also investigated. Their Tg can be adjusted between 30 and 55 °C by changing the ratio of monomers. The WSPs have good thermal stability at 350 °C. The static contact results show that the existence of sulfonic group enhances the hydrophilicity of WSPs. Compared with the waterborne acrylic polyester and polyurethane sold in the market, the prepared WSPs show excellent defoaming performance.
