Properties of a mechanically processed polymeric material

A semicrystalline polymer, polyamide, was processed using a new technique. The technique is that of mechanically grinding the material using large inputs of energy at temperatures below the glass-transition temperature and then later reconstituting the material by applying pressure and holding at a temperature below its melting point for a period of time. This technique is normally known as mechanical alloying and only very recently has been applied to polymeric materials. The mechanical properties of strength, ductility, toughness, and hardness of polyamide material processed by this technique are investigated and compared with those of polyamide material processed by other techniques. The results indicate that altered mechanical properties occur with specific enhancements. This means that useful structural components can be made from polymers using this processing technique. The analysis of x-ray diffraction, nuclear magnetic resonace, scanning electron and optical microscopy suggests that this process has resulted in considerable alteration of both crystal structure and microstructure of this polymeric material. © 1994 John Wiley & Sons, Inc.

Phase Inversion Technique-Based Polyamide Films and Their Applications: A Comprehensive Review

This is a comprehensive review regarding the particulars of phase inversion technique and its significance in polyamide films. Phase inversion is a versatile technique to form thin films of neat polyamide, composite, and blend system. Phase inversion can be induced by polymer solution immersion in nonsolvent, contact with nonsolvent vapor, thermal treatment, solvent evaporation, and quenching. Choice of solvent/nonsolvent system, polyamide, additive, coagulation bath, and film casting conditions are crucial. Only limitation of phase inversion is the requirement of polyamide solubility in suitable solvent. Promising applications of phase inversion polyamide are in fuel cell, gas separation, tissue engineering, and water filtration.     

Development of a polyamide nanocomposite for food industry: Morphological structure,processing, and properties

In the last few years, nanocomposites have been a focus of attention for researchers because they frequently exhibit unexpected hybrid properties derived from synergistic reactions between nanoparticles and the polymeric matrix. However, few studies about the dispersion of inorganic clay minerals in polyamide films have been carried out to explain the process of exfoliation. The exfoliation of nanoclays in the polyamide film provides a film with better barrier properties than the intercalation of nanoclays. The present study addresses the analysis of experimental variables (pressure, temperature, processing time, feed position, etc.) involved in the production of a polyamide film with nanoparticles, in order to obtain a film with good exfoliation, barrier and mechanical properties. SEM, TEM and XRD were also evaluated as tools to determine the degree of exfoliation of nanoparticles. The technique used in production of the film, the screw employed and the mixing time were found to be of great importance in obtaining an intercalated or exfoliated final product. The variables involved in obtaining an exfoliated Cloisite 30B/polyamide film by a double screw extruder were optimized, and a film with reduced permeability to oxygen (1,000 times lower than the control film) wasobtained.
