Type: article

Abstract: > 416 °C), high char yield (up to 72%), and flame-retardant behavior with a V-0 rating. The hybrids also exhibited favorable dielectric characteristics, with dielectric constants of 3.87-3.98 and low dielectric losses of 0.0070-0.0085 at 1 MHz. Furthermore, UV exposure at 365 nm for 72 h demonstrated excellent photostability of the poly(CB-PN-CE) hybrids. The synergistic incorporation of phthalonitrile, cyanate ester, and chalcone moieties endows the resulting hybrids with excellent thermal stability, flame resistance, UV stability, and favorable dielectric properties, making them promising candidates for high-performance thermosetting materials for thermally stable, flame-retardant, and electronic applications.
