Carbon black (CB) selective dispersion and conductive properties of immiscible thermoplastic/thermosetting polymer blends consisting of polystyrene (PS) and epoxy resin (EP) were investigated in this paper. The results showed that CB particles are preferentially localized in EP phase in PS/EP blends. The blend with 10 pbw (parts by weight) PS presented an EP continuous phase structure, and both blends with 20 pbw and 30 pbw developed into a bi-continuous phase structure. The selective dispersion of CB particles was explained by thermodynamic parameters. The phase structures of blends have important influences on both conductive and dielectric properties. The blends with 10 pbw PS has a very low percolation threshold nearly 0.25wt%.

Phenol novolac epoxy resin is a polymer matter which its properties can be modified for industrial needs. In this research, nanocomposites of phenol novolac epoxy resin and unsaturated polyester are made nano Bentonite and silica nanoparticles as filler. For this purpose, effect of nanoparticles percent on nanocomposite formation is studied and their physical, mechanical and thermal properties are obtained. The presence of unsaturated polyester in this process forms a cross-link capable of improving the physical and mechanical properties of epoxy resin. Fracture behavior was determined by a SEM device. Moreover, TGA, DSC, impact tests and bending test were applied for data analysis. When process ability is growing, moisture absorption decreases. Fracture toughness was also evaluated in a stoichiometric network. Physical and mechanical properties improve significantly with increasing nanoparticles. The most important reason for using this nanocomposite is its high resistance to corrosion.
