Abstract
Herein, we have reported the facile para-fluoro thiol click reaction to control microphase separation and the dielectric properties of poly(pentafluorostyrene-b-acrylic acid) copolymers. The block copolymer of pentafluorostyrene and acrylic acid was synthesized resulting in high block incompatibility by Nitroxide Mediated Polymerisation. By using the para-fluoro thiol reaction, 1-dodecanethiol was precisely clicked to block copolymers in various ratios. The microphase structures were observed in cylindrical geometry and their directionality was changed from parallel to perpendicular with increasing click ratio, besides domain size was recorded as low as 5.5 nm. The dielectric constant of the copolymers decreases with increasing click ratio due to the low dielectric constant of dodecane pendant groups and reaches κ=2.4 (at 1000 Hz). This study provides insights on one-step control over phase and dielectric properties by using a facile and very effective click reaction strategy that can simplify the fabrication of novel polymers for next-generation capacitor films for use in directed energy and advanced integrated circuits with smaller feature sizes.
