Synthesis, characterization, and thermal properties of phosphorylated chitin for biomedical applications.(Report)
May 1, 2009... INTRODUCTION Chitin, a natural polymer, is the second most abundant organic resource on the earth next to cellulose. It is an exoskeleton of crustacean, cuticle of insects, and the cell wall of fungi. Chitin is structurally similar to...

The effect of injection molding conditions on the morphology of polymer structural foams.(Report)
May 1, 2009... INTRODUCTION Injection molding of structural foam is one of the most suitable approaches to produce parts having a foamed core sandwiched between two unfoamed skins. This structure is known to have higher specific mechanical properties...

Preparation, characterization, and foaming behavior of poly(lactic acid)/poly(butylene adipate-co-butylene terephthalate) Blend.(Report)
May 1, 2009... INTRODUCTION Poly(lactic acid) (PLA) is known as a biodegradable thermoplastic polymer with widely potential applications (1), (2). The interest in environmentally friendly materials has stimulated development of extruded PLA-based foams....

Thermal conductivity and mechanical properties of aluminum nitride filled linear low-density polyethylene composites.(Report)
May 1, 2009... INTRODUCTION Polymers materials have gained wide applications in different branches of industry because of their low cost, low density, case of forming, chemical inertia, and low thermal conductivity (1). In some cases, however, high...

Gamma-irradiation effects on polypropylene-based composites with and without an internal lubricant.(Report)
May 1, 2009... INTRODUCTION AND SCOPE Gamma irradiation is known to have significant effects on properties of polymers and polymer-containing composites (1-18). At the same time, such irradiation is the most frequently applied method of sterilization, in...
