Tib2 Particles

A copper matrix composite reinforced with in situ TiB2 nanoparticle was successfully fabricated by tubulent in-situ mixing process. The microstructure, mechanical and electrical properties of the in situ composite were investigated. The results showed that the in situ formed TiB2 particles, in which size varying from about 50nm to 200nm, exhibited a homogenous dispersion in the copper matrix. It is shown that the interface between the nanoscale particles and the matrix was clean without a transitional layer. Because of the reinforcement, the hardness and Young’s Modulus of the composite improved with increment of cooling rate. Moreover, the in situ Cu-TiB2 composite exhibited higher electrical conductivity with increasing of cooling rate.

This study involved the development and characterization of novel porous, non-permeable, and conductive hydrogels. The hydrogels were fabricated with HEMA and crosslinked with PEGDA through a complete parametric study of the synthesis parameters which included water content and crosslinking content. The hydrogels were fabricated using UV photopolymerization and in situ polymerization of PPy, and characterization was conducted with respect to their physical, thermal, mechanical, and electrical properties. The physical properties were analyzed with respect to their swelling ratio and equilibrium water content. The thermal properties were analyzed based on the decomposition temperature and residue weight. The mechanical properties examined the elastic modulus of the hydrogels, and the electrical properties investigated the conductivity of the hydrogels. The relationships observed between the processing, structure, and resulting properties provide the basis for further development and application of these porous, non-permeable, and conductive hydrogels.

Fine Dispersion

Fine dispersion of graphenes is crucial for the application of graphenein various fields. However, graphenes are frequently aggregated due to the large surface area and van der Waals interactions between themselves during the mixing process. Thus, various modifications of graphenes are necessary for the fine dispersion. Introduction of functional groups into graphenes accompanies loss of inherent advantages. In this study, introduction of silver nanoparticles into graphenes by in situ process was investigated. Especially, microwave irradiation was employed for the syntheses sincegraphenes absorb microwave efficiently and became heated quickly. Formation of silver nanoparticles on the grapheneafter microwave irradiation was confirmed and the average diameter of the silver nanoparticles in the hybrids was about 30 nm. Rheological and electrical properties of the epoxy resins filled with the hybrids are discussed in this report.
