Synthesis And Properties Of Phenolic Based Hybrid Carbon Nanotube Inorganic Filled Composites

The use of a single filler in polymer composites does not always meet the on-demand requirements of an advanced polymer composite application. Therefore, producing a hybrid filler that contains more than one filler is necessary. Recently carbon nanotubes (CNTs) were hybridized with others fillers to...
