“…R1216 and HFPO are specialty fluorocarbons which have found extensive use in the fluorochemical industry. R1216 has gained prominence in both industrial and research activities and is utilized as an intermediate in chemical reactions, as a monomer in fluoropolymers, , in etching applications, and in epoxidation reactions for the manufacturing of HFPO. − The relatively more valuable commodity HFPO has found application in the manufacturing of high performance fluoropolymers and elastomers, in the production of high performance lubricating oils and heat resistant fluids, as a surfactant in ion exchange membrane applications, and in the manufacturing of rigid polyurethane foams…”

Experimental pure component vapor pressure data for hexafluoropropylene (R1216) and hexafluoropropylene oxide (HFPO) are presented. Experimental vapor-liquid equilibrium (VLE) data are presented at two temperatures, (273 and 313) K, for four binary systems: R1216 + toluene, HFPO + toluene, hexafluoroethane (R116) + R1216, and R116 + HFPO. The measurements were undertaken using both a "static-analytic" apparatus fitted with a pneumatic rapid online sampler injector (ROLSI) and a "static-synthetic" PVT apparatus. The experimental vapor pressure data were regressed to obtain correlated parameters for the Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) equations of state with the Mathias-Copeman R function. The binary VLE data were regressed to obtain correlated parameters for three different model combinations: the PR equation of state with the Wong-Sandler (WS) mixing rules, the PR equation of state with the modified Huron-Vidal first-order (MHV1) mixing rules, and the SRK equation of state with the WS mixing rules. The Mathias-Copeman R function and the nonrandom two-liquid (NRTL) excess Gibbs energy model were used in conjunction with the equations of state and mixing rules. In general, the PR equation of state with the WS mixing rules provided the best correlation for the experimental data. The critical lines for the supercritical systems R116 + R1216 and R116 + HFPO, calculated with the PR equation of state with the WS mixing rules, are also presented.

“…Ultrafine boron nitride particles are used as fillers in epoxy resins to improve the thermal conductivity of microelectronics packages. For this application, it is critical to appropriately disperse the boron nitride particles in order to reduce the viscosity of the slip and to increase the loading of particles for improved heat transfer (Bian et al, 2005).…”

“…So far, only a few investigations on plasma‐modified h‐BN particles have been reported. For example, Bian et al reported that a fluropropylene thin coating was formed on the surface of BN particles by using a plasma deposition technique [23]. In their study, the impact of surface modification on the rheological properties of SiR/BN compounds were investigated, but the thermal conductivity of the composite was not their concern.…”

Hexagonal boron nitride (h‐BN) fillers were first coated with low‐molecular‐weight polydimethylsiloxane (PDMS) by solution dispersion and then treated in argon plasma for different times. The modified h‐BN fillers were characterized by high‐resolution transmission electron microscopy, X‐ray photoelectron spectroscopy, and contact angle analysis. The results revealed that a thin PDMS film several nanometers thick was tightly coated on the surface of the h‐BN filler after plasma treatment, and this thin film could not be removed by 48 h Soxhlet extraction with n‐hexane at 120°C. Furthermore, the effect of plasma modification on the h‐BN filled silicone rubber composites was investigated. The results indicated that the plasma modification improved the interfacial interaction between h‐BN and the matrix, but hardly affected the distribution state of the h‐BN in the composites. The composites filled with the modified h‐BN exhibit significantly higher thermal conductivity than the composites filled with untreated h‐BN. POLYM.
