Fabrication of polymer nanocomposites

Since the development of nylon 6/clay nanocomposites by Kojima et al. [3,4] has been successful in tremendously reducing gas permeabihty, a large number of studies on polymer/organoclay nanocomposites have been reported. There are three different approaches possible to fabricate nanocomposites of polymers. The first one is the solution process. Clay is hydrophilic so that it can

Among the many potential applications of carbon nanotubes (CNTs), their use as reinforcing fillers for fhe fabrication of polymer nanocomposites has received considerable attention [1-4]. Both single-walled and multiwalled carbon nanotubes (SWCNTs and MWCNTs, respectively) are noted for their outstanding thermal, electrical, and mechanical properties. Polypropylene (PP) is a widely used thermoplastic because of its low cost, good processability, and well-balanced physical and mechanical properties. Products of PP take the forms of fibers, films, and molded articles. This chapter highlights the microstructure and properties of PP/CNT nanocomposites. Since most studies dealt with isotactic polypropylene, the term TP" in this chapter refers to isotactic polypropylene unless otherwise stated. 

FUTURE IMPROVEMENTS IN THE FABRICATION OF POLYMER NANOCOMPOSITE MEMBRANE... 

Fabrication of polymer nanocomposites consists of melting the polymer, mixing the polymer melt with the filler, extruding the molten mixture through the die, and collecting the extrudate. The extruder is heated to the desired polymer processing temperature and the desired screw speed and polymer feed rate are set. The polymer is fed from the overhead feeders through zone 1. Two different kinds of experiments were conducted - impulse input and step input of the filler.
