TL;DR: In this paper, a new processing technique is proposed for preparing AlN/polystyrene interpenetrating network composites based on an infiltration procedure, partly conducted in vacuo, of a liquid mixture of monomer and initiator into a porous A1N ceramic body with a percolated pore structure.
Abstract: A new processing technique is proposed for preparing AlN/polystyrene interpenetrating network composites. This technique is based on an infiltration procedure, partly conducted in vacuo, of a liquid mixture of monomer and initiator into a porous A1N ceramic body with a percolated pore structure. Successive in situ polymerization is produced by heating up the infiltrated ceramic at ≈100°C under ambient pressure. The final morphology of the composite consists of an interpenetrating polymer network which fills in an A1N ceramic skeleton. This new infiltration procedure enabled us to prepare continuous polymeric networks whose volume fraction lies between ≈12 and 40 vol%. These fractions of polymer are consistently lower than that usually involved in traditional polymer moulding processes. It is shown both by experiments and theory that these special interpenetrating network microstructures experience relatively high thermal conductivity. Concurrently, significantly improved fracture characteristics and reliability can be achieved as compared with both that of monolithic ceramics and traditional polymeric materials containing high fractions of ceramic filler.

TL;DR: In this paper, two types of PU-modified epoxy: PU-crosslinked epoxy and PU-dangled epoxy were synthesized, and the effects of the different molecular weights of polyol in the PU modified epoxy/PU IPNs on the dynamic mechanical properties, morphology, and damping behavior were investigated.
Abstract: Interpenetrating polymer networks (IPNs) were prepared from polyurethane (PU)-modified epoxy with different molecular weight of polyol and polyurethanes based on the mixture of polydiol and polytriol by a one-shot method. Two types of PU-modified epoxy: PU-crosslinked epoxy and PU-dangled epoxy were synthesized, and the effects of the different molecular weights of polyol in the PU-modified epoxy/PU IPNs on the dynamic mechanical properties, morphology, and damping behavior were investigated. The results show that the damping ability is enhanced through the introduction of PU-modified epoxy into the PU matrix to form the IPN structure. As the molecular weight of polyol in PU-modified epoxy increases, the loss area (LA) of the two types of the IPNs increases. PU-dangled epoxy/PU IPNs exhibit much higher damping property than that of the PU-crosslinked epoxy/PU IPNs with 20 wt % of PU-crosslinked epoxy. © 1999 John Wiley & Sons, Inc.
