The concentration of silane was fixed as the weight of silane relative to weight of fibres. Eg: In 5 wt% of silane solution, the 0.5 g of silane was dissolved in the ethanol/water solution for 10 g of fibres. So, is the amount of ethanol/water mixture important in silane treatment? Or the maximum amount of the mixture is 50 ml for 5 wt% of silane? Thank you very much
Ethanol / water is used to decrease the surface tension of the solution and allow the hydrolysis and silanol formation.
Which Silane Coupling Agent Are You Using?
Dear Mr. Thiago Felix,
Thank you for your feedback. I'm using APTES. I understand that ethanol/water is used to allow the hydrolysis of silane but I would like to know is there any negative effect if the amount of water is too high.
Thank you.
