Structures and Properties of the Coating for SPEEK/WPU

Abstract:

SPEEK can be dispersed in water as well as WPU, so the coating for SPEEK/WPU can be obtained in the water, and its films were investigated on the structures and properties by SEM, TGA, Shore Durometer and so forth, the results show that SPEEK as a micro-phase can disperse in WPU phase, and there is a good thermal stability when the temperature is below 290°C, and there is good improvement on the hardness of the films of coating that is about 60HA-65HA. The pH of the coating for SPEEK/WPU is about 7.0-8.0. The ratio of water absorption for films of the coating for SPEEK/WPU is about 10% and is below that of WPU, swelling of the films for solvents is also below that of WPU.
