Abstract
Aspects of the present disclosure provide for composite structures including a bonding layer that adheres a substrate (e.g., including a polymeric composition such as rubber) to a material (e.g., including a polymer such as polyurethane). The adhesion of the substrate to the material through the bonding layer can include chemical bonds such as, but not limited to, siloxane linkages, silanol linkages, silyl linkages, or any combination thereof in the bonding layer.
Claims13
A method of making an article of footwear, the method comprising:
- forming a bonding layer that comprises a plurality of silicates on a polymeric composition defining a surface of a component of footwear;
- contacting the bonding layer with a material comprising a plurality of polyurethane (PU) polymer chains;
- and
- forming chemical bonds between a portion of the plurality of silicates of the bonding layer and a first portion of the plurality of PU polymer chains of the material, thereby bonding the component of footwear to the material.
