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.

First claim

What is claimed:

1. An article of footwear comprising:
a composite structure comprising a material bonded to a component of footwear, the material comprising a plurality of first polyurethane (PU) chains, the component of footwear comprising a polymeric composition including a plurality of second polymer chains, wherein the component of footwear includes a first side including a bonding layer bonded to the material, wherein the bonding layer includes a plurality of chemical bonds between a portion of the plurality of first PU chains and a portion of the plurality of second polymer chains, wherein a portion of the chemical bonds include siloxane linkages, silanol linkages, silyl linkages, or any combination thereof.

2. The article of footwear of claim 1 , wherein the portion of the chemical bonds include urethane-siloxane linkages, urethane-silanol linkages, urethane-silyl linkages, or any combination thereof.

3. The article of footwear of claim 2 , wherein, with the exception of the bonding layer, the material is substantially free of PU chains including siloxane linkages, silanol linkages, and silyl linkages, and the polymeric composition of the substrate is substantially free of second polymer chains including siloxane linkages, silanol linkages, and silyl linkages.

4. The article of footwear of claim 1 , wherein the component of footwear includes a solid resin comprising the polymeric composition.

5. The article of footwear of claim 1 , wherein the component of footwear includes a foam comprising the polymeric composition.

6. The article of footwear of claim 1 , wherein the component of footwear includes a textile comprising the polymeric composition.

7. The article of footwear of claim 1 , wherein the polymeric composition of the component of footwear includes a plurality of polymer chains chosen from cured rubber polymer chains, polyether block amide polymer chains, ethylene vinyl acetate polymer chains, and any combination thereof.

8. The article of footwear of claim 7 , wherein the polymeric composition of the component of footwear includes the plurality of cured rubber chains, and the plurality of cured rubber chains include a plurality of polymer chains individually having a maleic anhydride moiety grafted to the polymer chain.

9. An article of footwear comprising:
a composite structure comprising a material bonded to a component of footwear, the material comprising a plurality of first polyurethane (PU) chains, the component of footwear comprising a polymeric composition including a plurality of second polymer chains, wherein the component of footwear includes a first side including a bonding layer bonded to the material, wherein the bonding layer includes a plurality of chemical bonds between a portion of the plurality of first PU chains and a portion of the plurality of second polymer chains, wherein a portion of the chemical bonds include urethane-siloxane linkages, urethane-silanol linkages, urethane-silyl linkages, or any combination thereof, and wherein, with the exception of the bonding layer, the material is substantially free of PU chains including siloxane linkages, silanol linkages, and silyl linkages, and the polymeric composition of the substrate is substantially free of second polymer chains including siloxane linkages, silanol linkages, and silyl linkages.

10. The article of footwear of claim 9 , wherein the component of footwear includes a solid resin comprising the polymeric composition.

11. The article of footwear of claim 9 , wherein the component of footwear includes a foam comprising the polymeric composition.

12. The article of footwear of claim 9 , wherein the component of footwear includes a textile comprising the polymeric composition.

13. The article of footwear of claim 9 , wherein the polymeric composition of the component of footwear includes a plurality of polymer chains chosen from cured rubber polymer chains, polyether block amide polymer chains, ethylene vinyl acetate polymer chains, and any combination thereof.

14. The article of footwear of claim 13 , wherein the polymeric composition of the component of footwear includes the plurality of cured rubber chains, and the plurality of cured rubber chains include a plurality of polymer chains individually having a maleic anhydride moiety grafted to the polymer chain.

15. An article of footwear comprising:
a composite structure comprising a material bonded to a component of footwear, the material comprising a plurality of first polyurethane (PU) chains, the component of footwear comprising a polymeric composition including a plurality of second polymer chains, wherein the component of footwear includes a first side including a bonding layer bonded to the material, wherein the bonding layer includes a plurality of chemical bonds between a portion of the plurality of first PU chains and a portion of the plurality of second polymer chains, wherein a portion of the chemical bonds include siloxane linkages, silanol linkages, silyl linkages, or any combination thereof, wherein the component of footwear includes a solid resin comprising the polymeric composition, or a foam comprising the polymeric composition, or a textile comprising the polymeric composition.

16. The article of footwear of claim 15 , wherein the portion of the chemical bonds include urethane-siloxane linkages, urethane-silanol linkages, urethane-silyl linkages, or any combination thereof.

17. The article of footwear of claim 16 , wherein, with the exception of the bonding layer, the material is substantially free of PU chains including siloxane linkages, silanol linkages, and silyl linkages, and the polymeric composition of the substrate is substantially free of second polymer chains including siloxane linkages, silanol linkages, and silyl linkages.

18. The article of footwear of claim 15 , wherein the polymeric composition of the component of footwear includes a plurality of polymer chains chosen from cured rubber polymer chains, polyether block amide polymer chains, ethylene vinyl acetate polymer chains, and any combination thereof.
