Exfoliated hexagonal boron nitride (h-BN) is considered an attractive fillers for various polymers because of its high thermal conductivity and resistance to oxidation, in addition to its moderate cost compared to other ceramic fillers. However, aggregation takes place easily when h-BNs are used to fabricate polymer composites and generate problems that affect their performance. Surface modification is the most important step when different phases of materials were incorporated into composites especially for nanocomposites. The popular method to modify the interfacial properties is the introduction of coupling agents to serve as a bridge to connect both hydrophilic and hydrophobic groups of two different materials. In this study, the rheological properties of h-BN suspensions dispersed in two type of resins, epoxy-silicone-acrylate and cycloaliphatic epoxy resin, were investigated from view point of different interfacial interactions between h-BN and the different matrix resins. |
