In order to improve the dielectric and overal properties of cyanate ester (CE) resin, a functional POSS monomer(octa(aminopropyl)silsesquioxane, POSS-NH2), was employed to modify CE. A series of POSS-NH2/CE hybrids (CE, CE1, CE2, CE3 and CE4) containing different content of POSS have been prepared by melt casting and then curing. The curing reaction of the resin systems were monitored by FT-IR. Dielectric properties of the hybrids were investigated in detail. FT-IR results showed the almost disappearance of the –OCN for all resin systems, suggesting the complete curing of CE using the experimental curing technique. Dielectric investigation indicates that CE1 which contains 1 wt% of POSS has the best dielectric properties with not only lowest dielectric constant but also lowest dielectric loss.

Properties Of Materials

Methylsilsesquioxane (Me-SSQ) was incorporated into cyanate ester resin (CE) to obtain organic-inorganic hybrids with better dielectric properties in this study. First, methyltriethoxysilane was hydrolyzed and condensed to synthesize Me-SSQ. Then several Me-SSQ/CE hybrids containing different contents of Me-SSQ were prepared. The effect of Me-SSQ content on the dielectric and hot/wet properties of materials was investigated. Results showed that the Me-SSQ/CE hybrid containing 20wt% of Me-SSQ shows a dielectric constant of 2.78, which is much lower than the pure CE resin. At the same time, the dielectric loss of the Me-SSQ/CE hybrids was slightly increased (tanδ<0.006). It indicates that Me-SSQ/CE hybrid is a promising matrix materials for high-performance printed circuit board (PCB).

A functional POSS monomer (POSS-NH2) was employed to modify cyanate ester (CE) resin. A series of POSS-NH2/CE hybrids containing different content of POSS have been prepared by melt casting and then curing. The curing kinetics and reaction mechanisms of the resin systems were studied by using FT-IR. Dielectric properties of the hybrids were also investigated. FT-IR results show that both temperature and POSS content may influence the curing reaction of CE. POSS-NH2 mainly displays the catalytic effect at higher temperature (220oC). The circumstance is more complex at lower temperature(190oC). CE1 containing 1 wt% of POSS has the best dielectric properties.
