Properties of hollow glass microsphere

2018-12-03 16:33:55 2055

Hollow glass microsphere–filled epoxy composites, with filler content ranging from 0 to 51.3 vol.%, were prepared in order to modify the dielectric properties of the epoxy. The results showed that the dielectric constant (Dk) and dielectric loss (Df) of the composites decreased simultaneously with increasing HGM content, which was critical for the provision of superior high-frequency device performance.

Other properties of the composite, such as the coefficient of thermal expansion (CTE) and the glass transition temperature (Tg), were also improved. The improvement in these properties was related to strong interaction between the HGM and epoxy, which was indicated by the formation of an interphase between the HGM and epoxy-matrix.

It was unsatisfactory in this study that the thermal conductivity of the composites also decreased with HGM content. In order to obtain relatively high thermal conductivity and a low dielectric constant simultaneously, this paper suggests further adding other filler.
