Abstract An overview of the progress in polymer nanocomposites is presented this paper with an emphasis on different methods used for preparing polymer‐layered silicate (PLS) and extent to which properties are enhanced. Other related areas that also discussed include types polymers PLS preparation, morphologies most commonly achieved, structure layered silicates, common techniques characterizing these nanocomposites. © 2007 Wiley Periodicals, Inc.

Abstract The morphology of blends polycarbonate and nylon 6,6 with a copolyester 60 mole percent p‐hydroxybenzoic acid/40 poly(ethylene terephthalate) was characterized under different processing conditions. In particular, single‐screw extrusion, steady simple shear flow, flow through capillary were studied to determine what conditions necessary for the development fibrillar liquid crystalline polymer (LCP). Results indicate that some extensional is required coalescence extension particulate...

Focusses on preliminary studies developing thermoplastic composite materials suitable for use in fused deposition modeling (FDM). Looks at thermotropic liquid crystalline polymers (TLCPs). Specifically aims to determine the feasibility of post‐processing TLCP strands generated by means dual extrusion process using FDM enhance tensile properties and functionality prototypes. Describes experiments gives in‐depth results which include finding that final mechanical a prototype can be tailored...
Abstract Blends of an engineering thermoplastic, poly(ethylene terephthalate) (PET), and two liquid crystalline polymers (LCPs) viz., copolyesters PET parahydrox‐ybenzoic acid (PHB) in 40/60 mole percent (LCP60) 20/80 (LCP80) were prepared. A blend LCP60 LCP80 50/50 weight (LCP60‐80) was blended with PET. Both flat films rods extruded their properties examined. The morphology the investigated using Scanning Electron Microscopy (SEM) revealed that LCP phase remained as dispersed droplets...

Abstract This paper reports on the tensile properties of microcellular foams three different thermoplastics, since there have been several in literature, but with indefinite conclusions so far, that microbubbles act a manner similar to rubber particles toughening thermoplastics. Polystyrene (PS), styreneacrylonitrile copolymer (SAN), and polycarbonate (PC), were selected based their intrinsic ductilities. The gas supersaturation technique was used generate samples microbubbles. effect...
Abstract The concept of generating liquid crystalline polymer (LCP) reinforcing fibrils on an in situ basis has a number potentially attractive advantages over the use more commonly used glass-reinforced composites. potential include wider range processing options, improved surface appearance, recyclability, and lower energy requirements. Many these have been discussed previous reviews such as those written by Dutta et al. [1] La Mantia Valenza [2]. However, to successfully compete with...
