ABSTRACT: Composites
based on melamine formaldehyde resins filled with exfoliated graphite or so
called nanographite have been prepared to achieve electrical conductivity and
improve mechanical strength and thermal stability. The nanographite was
synthesized by thermal treatment of oxidized graphite and the incorporation
into the melamine matrix was accomplished during the melamine formaldehyde
reaction. A homogenous dispersion of the filler in the matrix and the forming
of a connecting network based on graphite sheets were proved by SEM images. The graphite filler was able to increase the
flexural strength of molded testing specimens compared to unfilled resins and
electrical conductivity was achieved starting at 2 wt% nanographite.
