Abstract

Abstract: Ethylene-co-tetrafluoroethylene(ETFE)/nano-SiO2 composite coatings were prepared via flame spray. The degradation behavior of the composite coating was characterized using Fourier transform infrared spectroscopy, which confirmed that no oxidation nor degradation occurred during the flame spray. The non-isothermal crystallization and melting behavior were investigated using differential scanning calorimeter. It showed that the SiO2 particles promoted the heterogeneous nucleation and the crystallization temperature was increased by 2 oC, the melt point was also increased.

Key words: flame spray, ethylene tetrafluoroethylene, nano-silicon dioxide, non-isothermal crystallization, melting behavior
