Abstract
Methods and compositions are provided for enhancing the bonding of polymeric materials to substrates via silane coupling agents. The methods involve depositing an oxide layer, such as alumina or silica, to a substrate, for example stainless steel. Next a silane coupling agent is applied which forms a strong chemical bond with the oxide layer. This layer is then coated or contacted with a polymeric substance. The resulting composite provides a strong adhesive bonding of substrate to polymer.
