Studies on epoxy-polysulfone blend

Development and characterization of acid-doped polybenzimidazole/sulfonated polysulfone blend polymer electrolytes for fuel cells

Studies on Effect of Injection Timing of Graphene Nanoparticles Blended Simarouba Biodiesel Blend on CI Engine

Graphene is a monolayer carbon atoms discovered in the recent past which has inspired researchers in a wide range of applications. It has a surface area as high as 2630 m2/g and thermal conductivity value of 3000 W/mK-1 at room temperature. It is chemically the most reactive form of carbon with one carbon atom exposed to reaction from each side. Stable dispersion of graphene was achieved using ...

Chitosan/Poly(Amide-Imide) Blend Films: Studies on Thermal and Mechanical Stability, Morphology and Biodegradability

A diacid monomer was synthesized by the condensation of L-tryptophan amino acid and pyromellitic dianhydride (PMDA). The diacid was utilized for the synthesis of three types of poly(amide-imide)s (PAIs) using three different kinds of diamines. The synthesized monomer and PAIs were characterized using FT-IR, 1H-NMR and 13C-NMR spectroscopies and the PAIs were also used ...

Toxicity studies of cured epoxy resins.

Eliminating Volatile-Induced Surface Porosity During Resin Transfer Molding of a Benzoxazine/Epoxy Blend

We studied the mechanism of volatile-induced surface porosity formation during the resin transfer molding (RTM) of aerospace composites using a blended benzoxazine/epoxy resin, and identified reduction strategies based on material and processing parameters. The influence of viscosity and pressure on resin volatilization were determined. Then, in situ data was collected during molding using a la...
