Thermal and Dielectric Properties of High Performance Polymer/ZnO Nanocomposites

investigation of gassing behavior, electric and dielectric properties of different insulating fluids.

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...

Dielectric Properties of Graphite Nanocomposites

Magneto-dielectric properties of polymer– Fe3O4 nanocomposites

The aim of this research is to elucidate the size effect of magnetic nanoparticles on the resultant magneto-dielectric properties of polymer nanocomposites at radio frequencies. The block copolymer of [styrene-b-ethylene/butylene-b-styrene] (SEBS) was utilized as a matrix for the templating of magnetic nanoparticles. Surfactant-modified iron oxide (Fe3O4) nanoparticles of various sizes were suc...

Dielectric Properties of PE/Clay Nanocomposites

Polyethylene/nanoclay specimens containing from 0 to 5% nanoclays were prepared from a commercially available premixed PE/nanoclay masterbatch containing 50%wt of nanoclay. The masterbatch was diluted to the desired concentration by adding PE along with various amounts of compatibilizer in order to achieve the best possible dispersion of the nanoclay platelets. The dielectric response of the co...

Octasilsesquioxane reinforced DGEBA and TGDDM epoxy nanocomposites: Characterization of Thermal, Dielectric and Morphological properties

The octa-functionalized polyhedral oligomeric silsesquioxane (POSS) containing nanocomposites of epoxy resin are prepared via in situ co-polymerization of epoxy resins with 4,4’-diaminodiphenylsulfone (DDS) in the presence of octaaminophenyl silsesquioxane (OAPS). Two of the most common, technologically relevant epoxy resins, diglycidyl ether of bisphenol-A (DGEBA) and tetraglycidyl diamino dip...
