Abstract
Novel pro-adhesive surface layers on a steel substrate were created via electrostatic adsorption of montmorillonite platelets on ammonium silane layers based on (3-aminopropyl)trimethoxysilane. Morphology of the mentioned montmorillonite-ammonium silane surface layers (MSL) (prepared using clays with calcium, strontium and diisopropylammonium exchangeable cations) was analysed by means of SEM, EDX and XRD techniques. The MSL significantly reduced dipropylene glycol contact angle (?14
