Poly(2,5-benzimidazole) Based Polymer Electrolyte Membranes for High Temperature Fuel Cell Applications

Bao X.J., Liu Q.T., Loughborough University, UK

In this study, two methods, direct mixing polyhedral oligomeric silsesquioxanos (POSS) with poly(2,5-benzimidazole) (ABPBI) and in-situ synthesis were employed to prepare ABPBI based composite membrane materials, respectively. The morphologies of pristine and composite membranes were [...]

Polymer nanocomposites: an advanced material for functional fibers

Joshi M., Indian Institute of Technology, IN

The paper illustrates our development in the area of producing fibers from polymer nanocomposites both through melt and solution intercalation route. The polymers studied are Polypropylene, Polyethylene Polyurethane and Nylon. The naofillers used range from [...]

The Effects of POSS on the Interlaminar Shear Strength of Marine Composites under Various Environmental Conditions

Mahfuz H., Powell F., Granata R., Hosur M., Florida Atlantic University, US

The fiber/matrix (F/M) interface of carbon/vinyl ester composites has been modified by treating the carbon fiber with polyhedral oligomeric silsesquioxane (POSS). The objective was to improve the durability of the F/M interface in various environments. [...]

Thermal and Mechanical Response of POSS coated Nanophased expandable foam core materials

Jones W.D., Rangari V.K., Jeelani S., Tuskegee University, US

A sonochemical technique has been established to coat variations of POSS nanoparticles on expandable microspheres. Thermal analyses results indicate that there is an increase in thermal stability of nanophased foam as compared to the neat [...]

Nano-Reinforcement of Epoxy Adhesives with POSS

Chian W., Mallampalli C., Winter R.M., South Dakota School of Mines & Technology, US

ABSTRACT The reinforcement of epoxy adhesive with polyhedral-Oligomeric-SilSesquioxane (POSS) was studied. Shear performance of the nano-filled adhesive was evaluated as a function of filler content using the single-strap bonded joint configuration. It is found that [...]
