Influence of Acetic Acid on Dynamic Behavior of Hydrolazation and Film Forming of Organosilane
The influence of acetic acid on dynamic behavior of hydrolazation and film forming of an expoxy-silane compound (y-GPS) was investigated by conductivity meter, IR and AFM. The experimental results show that there is an optimal pH value(pH=4-5) for hydrolysis of silane solution, and with the prolonga...

Summary: | The influence of acetic acid on dynamic behavior of hydrolazation and film forming of an expoxy-silane compound (y-GPS) was investigated by conductivity meter, IR and AFM. The experimental results show that there is an optimal pH value(pH=4-5) for hydrolysis of silane solution, and with the prolongation of hydrolytic time, the promotion of acetic acid on the hydrolyzation of silane solution become more obvious. During the adsorption and film forming process, acetic acid could promote the formation of Si-O-Fe bond, which activates hydroxyl group of silanol unit and facilitates this hydroxyl group to react with adjacent silanol unit forming linear condensation polymers. |
