Deposition and characterization of poly(o-anisidine)/TiO2Nanocomposite for gas sensing application
Abstract: The Poly(o-anisidine) (POA) and Titanium dioxide POA (POA/TiO2 ) composite thin film based for gas sensing application are synthesized. Pure POA and POA/TiO2 composites with 20wt% of TiO2 were synthesized by chemical oxidative polymerization of o-anisidine using ammonium persulfate in acidic medium at 0-50C. Thin films of POA and POA/TiO2 composites were deposited on glass plate by dip coating method to prepare the chemiresistor sensor. The structural and optical properties …

Study of Dynamic Mechanical and Thermal Properties of Poly(Ether Ether Ketone) Carbon Nanotubes
Abstract: The effect of polyetherimide (PEI) as a compatibilizing agent on the morphology, thermal, electrical and dynamic-mechanical properties of poly(ether ether ketone) (PEEK)/single-walled carbon nanotube (SWCNT) nanocomposites, has been investigated for different CNT loadings. After a pre-processing step based on ball milling and premixing under mechanical treatments in ethanol, the samples were prepared by melt extrusion. A more homogeneous distribution of the CNTs throughout the matrix is found for composites containing …

Low temperature plasma treatment of polymeric membranes: a comparative review
Abstract: This paper presents a comparative study of plasma surface modification of various polymeric membranes. Low temperature plasma treatment using pulsed direct current discharge of different gases was employed to enhance hydrophilicity of membranes. Radio frequency discharge of various gases was used to improve surface properties of different polymeric membranes. The enhancement of hydrophilicity of the plasma modified membrane surface was evaluated by measuring the contact angle. The membranes were characterized …
