Research Progress on Polymeric Inorganic Nanocomposites Insulating Materials

Abstract

With the rapid development of power energy, electronic information, rail transit, and aerospace industries, nanocomposite dielectric materials have been widely used as new materials. Polymer/inorganic nanocomposite dielectric materials possess excellent physical and mechanical properties. In addition, numerous unique properties such as electricity, thermal, sound, light, and magnetic properties are exhibited by these materials. First, the macroscopic quantum tunneling effect, small-size effect, surface effect, and quantum-size effect of nanoparticles are introduced. There are a few anomalous changes in the physical and chemical properties of the matrix, which are caused by these effects. Second, the interaction mechanism between the nanoparticles and polymer matrix is introduced. These include infiltration adsorption theory, chemical bonding, diffusion theory, electrostatic theory, mechanical connection theory, deformation layer theory, and physical adsorption theory. The mechanism of action of the interface on the dielectric properties of the composites is summarized. These are the interface trap effect, interface barrier effect, and homogenization field strength effect. In addition, different interfacial structure models were used to analyze the specific properties of nanocomposite dielectric materials. Finally, the research status of the dielectric properties of nanocomposite dielectric materials is introduced.

Recent Applications and Evaluation of Metal Nanoparticle–Polymer Hybrids as Chronic Wound Dressings

“…Nanotechnology has recently provided an excellent approach to enhancing acute and chronic wound healing by encouraging proper mobility throughout the numerous stages of healing [78]. Nanoparticles (NPs) have been highlighted as an effective wound healing therapy technique among all other nanomaterials due to their ability to function as both a therapeutic and carrier system, as well as many other unique properties [79,80]. Cerium oxide (CeO 2 ) nanoparticles (CONPs) are employed in a variety of medicinal applications due to their antiinflammatory, anticancer, and proangiogenic characteristics [76,[81][82][83][84].…”
