Deposition of Boron nitride nanoparticles on polyamide fabrics

Purpose of research . Fixation of Boron nitride nanoparticles on polyamide fabric. Methods . Colloidal systems were stirred and dispersed in an ultrasonic bath QUICK 218-35 with an emitter power of 50 W and an ultrasonic technological disperser “Volna” UZTA-0.4/22-OM. The activation of the polyamide fabric surface and its cleaning were carried out by plasma treatment in a low-pressure PICO system. Deposition of nanoparticles using the Langmuir-Blodgett method was performed on a KSV Nima 2002 setup. The morphology and elemental composition of the polyamide fabric before and after the application of boron nitride nanoparticles were studied using a JEOL 6610LV scanning electron microscope equipped with an Oxford Instruments X-Max energy-dispersive X-ray analyzer. The research methodology included the use of a low-vacuum mode, which was important for preventing the accumulation of surface electrical charge on dielectric samples. Results . Sediment-resistant colloidal systems were synthesized based on boron nitride nanoparticles stabilized with stearic acid and an aqueous solution of Boron nitride nanoparticle powder with the addition of an oiling agent. Nano-particles from the first colloidal system were deposited on polyamide fabric using the Langmuir-Blodgett method, while nanoparticles from the second system were applied by immersing the fabric in the system with ultrasonic dispersion. SEM images of the polyamide fabric and its energy-dispersive analysis confirm the uniform fixation of boron nitride nanoparticles on the fibers by these methods. Conclusion . In this work, boron nitride nanoparticles were fixed onto polyamide fabric using the Langmuir-Blodgett method and by immersing the fabric in a colloidal system with ultrasonic dispersion. This allowed for uniform deposition of nanoparticles both on the surface of the polyamide fabric and between the fibers, enhancing its performance characteristics.
