The copolymerization of aryl bis‐ and tris‐trifluorovinyl ether monomers yields aromatic perfluorocyclobutyl (PFCB) polymers, via thermally initiated step‐growth cycloaddition chemistry. PFCB polymers and their copolymers enjoy a unique combination of attributes well suited for applications in photonic technologies, such as broad tailorability of refractive indices and thermo‐optic coefficients, low transmission losses at 1300 and 1550 nm, high thermal, mechanical, and optical stability, and excellent melt and solution processability. Planar PFCB structures can be processed by direct micro‐transfer molding, which is a first step towards rapid soft‐lithographic fabrication of polymer planar lightwave circuits. Copolymerization chemistry and processing parameters and characterization, including thermal (Tg = 120–350 °C) and optical properties (refractive indices from 1.443 to 1.508 at 1550 nm; thermo‐optic coefficients dn/dT = –7×10–5 K–1 to –1.5 × 10–4 K–1), birefringence (< 0.003), and temporal stability of refractive index, are described.

“…Rajesh Theravalappil et al [11] showed that owing to the larger length and diameter of the CF filler, CF/EOC composites possessed higher conductivity than the MWCNT composites at all concentrations and the conductivity increased with raising filler loading. The carbon fiber coated with metal can not only maintain the advantages of carbon fiber such as high strength, high stiffness, and low density [13,14], but also further increase the conductivity [15]. In addition, Shuaiguo Zhao et al [16] found that by introducing 0.155 vol% CFs into the segregated CB/PP composite, the percolation threshold of the conductive composite reduced significantly, and the conductivity improved.…”

The property of polycarbonate/acrylonitrile butadiene styrene‐based conductive composites filled by nickel‐coated carbon fiber and nickel–graphite powder

The filled conductive composites were prepared with a polycarbonate/acrylonitrile butadiene styrene matrix and both nickel‐coated carbon fiber (NiCF) and nickel–graphite powder (NCG) as fillers by using injection molding and injection‐compression molding. The effect of the NiCF content, NCG content, coupling agent, and molding methods on the properties of composites was studied. The results showed that the conductivity of the composites increased with raising the NiCF content and NCG content. NiCF treated with silane coupling agent could further improve the conductivity of the composites without any significant change in mechanical properties. Furthermore, compared with injection molding, the composites prepared by injection‐compression molding possessed better conductivity. POLYM.

“…4 Many kinds of fluorinated polymers aimed at various applications, such as films, coatings for microelectronics and optical devices, gas-separation membranes, and matrix resins in fiber-reinforced composites, have been synthesized. [5][6][7][8][9] Fluorinated aromatic polyformals have been synthesized from 2,2-bis(4-hydroxyphenyl)-1,1,1,3,3,3-hexafluoropropane and methylene chloride [10][11][12] in the presence of KOH as a base and N-methyl-2-pyrrolidinone as a solvent. These fluorinated aromatic polyformal homopolymers have T g 's about 30 8C higher than those of their nonfluorinated analogues.…”
