Abstract:

Abstract In order to study the influence of BC (bacterial cellulose) on acrylic-based carbon fabric, acrylic-based fabric and BC as raw material and starch as adhesives, acrylic-based carbon fabric and acrylic-based/BC carbon fabric composite materials were prepared by pre-oxidation (heating rate 1 ℃/min, pre-oxidation temperature 250 ℃, pre-oxidation time 5 h) and carbonization (heating rate 5 ℃/min, carbonization temperature 900 ℃, carbonization time 8 h). Scanning electron microscopy (SEM), Four-probe tester (FPT), Fourier transform infrared spectroscopy (FT-IR) and laser Raman spectroscopy (Raman) were used to characterize the morphology, electrical properties and structure. The results showed that the surface of acrylic-based/BC carbon fabric makes more smooth; nanostructure surface modification improves the conductivity of the fibers and reduces the difference in conductivity which carbon fabric are about 0.05 S/m; cyano nitrile groups are more fully transformed by BC surface modification; the degree of graphite relative increase, whereas there are no appreciable changes.
