Nanofiller effect during post-heat treatmentof micro-loaded epoxy

Samples of epoxy filled with micrometric quartz were prepared with or without the addition of a small amount of nanoclay, in regard to the quartz content. The influence of the nanofiller on heat treatment after curing was characterized using dielectric spectroscopy. It was put in evidence that the addition of nanofillers caused an increase of the relaxation time of the α relaxation process, altered the kinetic of the post-curing and of the water diffusion processes but did not affect the β relaxation rate.
