Abstract: The present disclosure relates to a method for stably dispersing nanoparticles of a material in a curable polymer, the method comprising: a) providing a curable pre-polymer; b) providing particles of the material; and c) compounding the curable pre-polymer and the particles at a compounding temperature sufficiently high to obtain a curable melt mixture and sufficiently low for the curable melt mixture to develop a pre-determined viscosity upon compounding. The compounding is performed by applying a shear force to the heated curable melt mixture, whereby nanoparticles are formed from the particles, the viscosity of the melt being such that the nanoparticles remain dispersed in the mixture.
