Objective: A new poly(ionic liquid)(PIL), poly(p-vinylbenzyltriphenylphosphine hexafluorophosphate) (P[VBTPP][PF6]), was synthesized by quaternization, anion exchange reaction, and free radical polymerization. Then a series of the PIL were synthesized at different conditions. Methods: The specific heat capacity, glass-transition temperature and melting temperature of the synthesized PILs were measured by differential scanning calorimeter. The thermal conductivities of the PILs were measured by the laser flash analysis method. Results: Results showed that, under optimized synthesis conditions, P[VBTPP][PF6] as the thermal insulator had a high glass-transition temperature of 210.1°C, high melting point of 421.6°C, and a low thermal conductivity of 0.0920 W m-1 K-1 at 40.0°C (it was 0.105 W m-1 K-1 even at 180.0°C). The foamed sample exhibited much low thermal conductivity λ=0.0340 W m-1 K-1 at room temperature, which was comparable to a commercial polyurethane thermal insulating material although the latter had a much lower density. Conclusion: In addition, mixing the P[VBTPP][PF6] sample into polypropylene could obviously increase the Oxygen Index, revealing its efficient flame resistance. Therefore, P[VBTPP][PF6] is a potential thermal insulating material.

Casting Technique

The blend-based polymer electrolyte consisting of chitosan and polyvinyl alcohol (PVA) as host polymers and potassium hydroxide (KOH) as the complexing salt was studied. Polymerelectrolyte were obtained by the casting technique. An attempt was also made to investigate the effect of TiO2 concentration in the chitosan/PVA+KOH polymer electrolyte. The best ionic conductivity values of 1,105 x 10-2 S cm-1 at room temperature were obtained for the sample containing 35%wt of KOH and 1,210 x 10-2 S cm-1 for the sample containing 50% wt TiO2. The polymer electrolyte with good ionic conductivity properties were characterized by thermal analysis (DSC). The glass transition temperature about 75.30 °C for the optimum Chitosan/PVA+KOH
