Stretchable conductive composites have received considerable research interest recently for high-end microelectronic applications. Here we report conductive and stretchable composites by incorporating various shape-modified silver fillers into polyurethane elastomer matrix. By selecting soft and hard segments of polyurethane, the polymer resin can not only provide sufficient stretchability/flexibility,...
Highly conductive anisotropic conductive films (ACFs) with in-situ reduced silver nanoparticles as fillers were developed. During the preparation of ACF formulation, the silver nanoparticles were reduced by the hydroxyl groups from the phenoxy resin through the polyol process. Due to the capping effects of the epoxy resin, the in-situ reduced silver nanoparticles were well dispersed in the polymer...
Considerable attention has been devoted to the synthesis and application of nanoparticles because of their unusual physical and chemical properties resulted from the ultra-fine size and ultra-large surface area. Polymer composite materials based on metal nanoparticles provide a potential solution to meet the present and future technological demand in virtue of the good processibility and mechanical...
In this paper, the novel biocompatible materials were created on the basis of creation of the bio-inert superhydrophobic surfaces using a heat curable polydimethylsiloxane (PDMS, Sylgard 184, a product of Dow Corning) and polytetrafluoroethylene (PTFE) particles. The incorporation of PTFE nanoparticles in the PDMS matrix allows the formulation of superhydrophobic films with contact angles of ~160deg...
In order to accommodate environmental considerations, the environmentally friendly and biocompatible materials become increasingly important and attract a lot of research interest in recent years, while application of biocompatible materials are still in its infancy. In this paper, the biochemical building blocks, amino acid is used as a novel environmentally benign and biologically compatible curing...
Conductive filler-polymer composite materials have been extensively investigated as conductor-insulator percolative system to achieve high dielectric constant (K). Additionally, the effective dielectric constant of conductive filler/polymer composite can be dramatically enhanced by increasing the dielectric constant of polymer matrix according to scaling theory. However, the high dielectric loss of...
