The kinetics of the surface reaction between Porous Silicon and aminopropyl-triethoxy silane (APTES) was studied using FTIR to determine the rate law and optimum attachment conditions. Results suggest that once a monolayer is established, the APTES undergoes a zero order polymerization to form multilayers. Further surface architecture was explored in-which the reaction between 4-(methylthio) benzoyl chloride with the amino silanized porous silicon plates was studied to determine the rate law for attachment using FTIR. The reaction was carried out under pseudo first order conditions and confirmed a second order overall rate law.
