Poly(N-vinylcarbazole) (PVK) composites containing different concentrations of cellulose triacetate (CTA) were synthesized through oxidative polymerization of N-vinylcarbazole with ferric chloride. Characterization and thermal stability of the synthesized composite were investigated using Fourier transform infrared (FTIR) and ultraviolet—visible (UV—Vis) spectroscopy, and thermogravimetric analysis (TGA), respectively. Surface morphology of the synthesized composites was studied using both scanning and transmission electron microscopy. Well-ordered porous films of the polymer composites were fabricated by evaporation of the composite solution dissolved in a volatile solvent under humid conditions. The PVK—CTA composite formed a highly well-ordered honeycomb pattern with the appropriate concentration of CTA in the absence of any kind of amphiphilic copolymer to stabilize the air—water interface. Findings of this study indicate that uniformly dispersed CTA is responsible for the stability of the air—water interface in the composite solution, thus enabling the formation of a highly ordered polymer film.

This study deals with effect of plasma treatment on the properties of unidirectional ligno cellulosic fabric Hildegardia Populofolia (HDP) fabric. Thermal stability of the fabric was determined by differential scanning calorimetry (DSC) and Thermo gravimetric analysis (DSC). Morphological properties was analyzed by SEM analysis and found that the surface was rough upon plasma treatment which provides good interfacial adhesion with matrix during composite fabrication. Thermal stability and mechanical properties of the plasma treated fabric slightly increases compare to alkali and untreated fabric. It was observed that tensile properties of the fabric increases upon plasma treatment due to the formation of rough surface. SEM analysis indicates formation of rough surface on plasma treatment which helps in increasing the interfacial interaction between the matrix (hydrophobic) and fabric (hydrophilic).
