ABSTRACT
The compounding and compatibilization of the high-performance polymer alloys, blends, and composites is very important. The properties of polymer alloys, polymer blends, and polymer composites depend on the quality of the dispersed phase, the microstructure of all phases, the adhesion and cohesion between phases, and the morphology of the system. The modification of a polymer’s properties through a physical blending process has been of increasing importance. The impact strength of composites is even more complicated than that of unfilled polymers because of the added reinforced fiber. The affinity can be improved by activating the filler’s surface or modifying the polymer and is also determined by whether the polymer or the filler bears polar functionalities. Flame-retardant plasticizing polymers generally decrease thermomechanical properties. Strength varies with small amounts of additives because an additive acts as a damper and redistributes the internal stresses or fills defects within the microstructure of the bulk polymer.
