Development of polyimide/metal gradient microcomposite films
… soluble metal compounds in an effort to create microcomposite films in which the location of the composite structure was controlled; namely at the film interfaces. Two different modification techniques were used in this study, in-situ chemical generation and infusion deposition. Results indicate …

Study of a microcomposite metal-doped polyimide adhesive
It is widely held in the field of adhesion science that the properties of the interfacial region, or interphase, between two bonded surfaces are of critical importance to the performance of an adhesive bond. This thesis describes a study in which a polyimide was modified by the addition of metal …

Poly(amide acid) infusion with Copper(II) Chloride to form polyimide microcomposite films
Polyimides are well known for their high thermal stability, chemical inertness, and their high electrical resistance. These properties make them ideal for use in the aerospace and electronics industries. Often polyimides are modified by coating or doping the films with metal species to change the …

Synthesis of Functionalized Polysiloxanes and Investigation of Highly Filled Thermally Conductive Microcomposites
… networks. The intention was to generate stable microcomposite dispersions with very high concentrations of polar thermally conductive fillers. Lightly crosslinked elastomeric networks with controlled amounts of polar moieties were prepared via a hydrosilation curing mechanism. High …

Processing-Structure-Property Relations in Novel Organocement Composites
… from CaAl$\sb2$O$\sb4$-coated Al$\sb2$O$\sb3$ microcomposite powders were fabricated. These composites contained a negligible amount of unreacted CaAl$\sb2$O$\sb4$ and a moderate reduction in bulk polymer content and exhibited initial strengths comparable to those reported for conventional …

Preparation and characterisation of poly(ethylene terephthalate) and poly(vinyl alcohol)/clay nanocomposites.
… be dependent on the dispersion of the clay with microcomposite structures resulting in better barrier properties than their nanocomposite counterparts. Higher temperatures resulted in faster diffusion rates. During the diffusion of water crystalline regions of the PVOH were dissolved and the clay …

Injection Molding of Pregenerated Microcomposites
… concerned with injection molding pregenerated microcomposites composed primarily of poly(ethylene terephthalate) (PET) as the matrix and HX1000 as the thermotropic liquid crystalline polymer (TLCP). Several factors were examined to maximize the mechanical properties of these composites, …

The processing of microcomposites based on polypropylene and two thermotropic liquid crystalline polymers in injection molding, sheet extrusion, and extrusion blow molding
… liquid crystal polymers (TLCPs), referred to as microcomposites. The processing methods used are injection molding, sheet extrusion, and extrusion blow molding. The TLCPs used are HX6000 and Vectra A950. The microcomposites are produced by drawing strands of PP and TLCPs generated by means of a …
