Fabrication of Poly (Acrylonitrile-Co-Methyl Methacrylate) Nanofibers Containing Boron via Electrospinning Method: A Study on Size Distribution, Thermal, Crystalline, and Mechanical Strength Properties

Electrospun polymeric nanofibers have attracted great attention in filtration systems and protective clothes. One of them is polyacrylonitrile (PAN) nanofibers, which are a suitable choice for the fabrication clothes defense industry, due to their good fiber formation easy optimization with chemical reagents. They do not possess adequate properties protection against chemical, biological, radiological agents. In this research, poly (acrylonitrile-co-methyl methacrylate) (PANMM) PANMM containing 10B were fabricated via electrospinning method. The study morphology using scanning electron microscopy (SEM), revealed that smooth knotted fibers an average diameter 259 ± 64 nm obtained, 12% (w/v) solution as optimal concentration process. This sample was doped boron (10%, 30%, 50% (w/w)) fabricate samples + boric acid (BA) nanofibers. results demonstrated increasing trend increase BA up 50%. At concentration, formed lower knots. Furthermore, presence B-O O-H groups observed Fourier transform infrared (FTIR) spectroscopy. To tensile properties, nanofibrous web tested, showed introducing nanofiber structures reduced strength Thermal gravimetric analysis (TGA) BA-modified had thermal degradability, compared pure PANMM.
