After dipping my stainless steel mesh in teos solution i dried it in oven at 110C. after allowing some time i immersed my mesh in 0.2m Chlorotrimethylsilan(*ctms) in hexane. After 5 min mesh absorbed the whole 15ml of ctms solution. also i didnt get the hydrophobic coating. why it has happen

* Teos solution was added along 50 ml ethanol and 3 ml of ammonium hydroxide
