查询词典 shielding effect

In this study, the electrical conductive composites (comprised of thermoplastic matrix resins-high density polyethylene, polyphenylene sulfide and polyarylethersuifone with cardo group, and conductive fillers-short carbon fiber, carhon black and graphite) are prepared and characterized in detail.
