Synthesis and characterization of fluorinated polybenzoxazine material with low dielectric constant

Low dielectric materials from fluorinated polybenzoxazines

“…Hence, the synthesized polymers are well suited for ILDs requiring high-temperature applications. [8] 329.0 363.6 --Poly (BF-1) [8] 374. 4 455.7 --Selected polybenzoxazines: poly (BA-a), from bisphenol A and aniline; poly (BF-1), from bisphenol F and (trifluoromethyl) aniline.…”

“…The disadvantages of the typical Pbzs are the high temperature needed for complete curing and the brittleness of the cured materials that can sometimes limit their potential applications. [8,9] In recent years, the preparation of Pbzs with a low dielectric constant and high performance has become one of the main research focuses. Low-dielectric-constant materials (k < 3.0) have the advantage of facilitating manufacture of high-performance integrated circuit (IC) devices with decreasing feature size of the chip.…”

“…[10][11][12][13] Several approaches have been made to reduce the dielectric constant of Pbzs, which include incorporation of a fluorinated substituent into Pbzs, nanoporous material of poly(caprolactoneco-benzoxazine), and polyoligomeric silsesquioxane (POSS)-Pbz nanocomposites. Chang et al [8] synthesized fluorinated benzoxazine using biphenol F and alanine and trifluoromethyl aniline. A coPbz of this fluorinated benzoxazine with nonfluorinated benzoxazine based on bisphenol A and aniline (BA-a) showed a dielectric constant of 2.36 on 50/50% w/w blend.…”

Thermal degradation of polysiloxane and polyetherester containing benzoxazine moieties in the main chain

“…In order to enhance the performance characteristics and to decrease the polymerization temperature, various approaches have been applied. These approaches include the modification of the monomer, preparation of polymer alloys of polybenzoxazine with high performance polymers or with elastomers, use of fiber reinforced composites and the hybridization with inorganic materials such as layered and metal oxide nanoparticles [12][13][14][15][16].…”

High‐Tg and low‐dielectric epoxy thermosets based on a propargyl ether‐containing phosphinated benzoxazine

“…For example, Su and Chang prepared a low-dielectric polybenzoxazine based on a hexafluorobisphenol A and 4-(trifluoromethyl)aniline-based benzoxazine. 4 Lin et al prepared low-dielectric polybenzoxazines from fluorinated diamines and phenolbased benzoxazines. 5 Velez-Herrera et al prepared lowdielectric polybenzoxazines from highly fluorinated aliphatic diamines and 4-fluorophenol-based benzoxazines, and fluorinated aromatic diamines and hexafluorobisphenol A-based benzoxazines.…”
