Preparation and Properties of Nanocomposites Consist of Carbon Black N220 and Epoxy Resin
The nanometer carbon black (CB) N220 of different content was employed to prepare carbon black N220/epoxy resin (CB N220/EP) composites by filling-mixing method. The structure of CB N220 and its dispersion in epoxy resin were analyzed by TEM and tensile fracture surface of the composites was analyzed by SEM. Experimental results showed that CB N220 was dispersed in epoxy resin homogenously in the form of CB particles and it formed a good interface with epoxy resin in the presence of coupling agent (KH-550). Using of CB N220 enhanced the mechanical and thermal properties of the composites, for tensile strength, elongation at break, impact strength and ﬂexural strength of the composites ﬁlled with 2 wt% CB N220 reached a maximum values( 82Mpa、3％、20 KJ•m-2、107Mpa), a rise of 32.3％、39.6％、88.7％、10.3％, respectively, compared to pristine epoxy resin.
