Fabrication and characterization of novel polyacrylate films with hindered phenol structures and fluorine groups

Abstract

Abstract A series of novel fluorinated-damping polyacrylate (OFDA) emulsions based on a series of novel hindered phenol fluorinated acrylates (OFIP-AO 1010-HEA) were prepared successfully. The structure of OFIP-AO 1010-HEA was characterized by fourier transform infrared spectroscopy (FTIR). The influence of OFIP-AO 1010-HEA on different properties of the OFDA films was investigated by using dynamic mechanical analysis (DMA) and the measurement of contact angle. The results showed that the OFDA6 film owns 0.75 in tan δpeak and its loss factors ≥ 0.3 was spanning widely from -80 °C to 200 °C. So the OFDA6 film had the best damping properties. While OFDA4 had the best in the contact angle of water and the lowest surface free energy.
