Abstract
Official abstract text for this publication.
Systems and processes for forming seals. The seals have graphene embedded in the seal. The graphene-embedded seals exhibit improved wear resistance over seals without graphene.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming a graphene-embedded seal comprising: mixing graphene and alcohol forming a graphene alcohol solution; and cold pressing polymer powder to form a pressed seal powder; exposing the pressed seal powder to the graphene alcohol solution wherein a portion of the graphene alcohol solution infiltrates the pressed seal powder forming an infiltrated pressed seal powder; and sintering the infiltrated pressed seal powder forming a polymer seal having graphene embedded within the polymer seal. 2. The method of claim 1 , wherein the graphene and alcohol solution comprises 0.1-10 mg/L of graphene. 3. The method of claim 2 , wherein the graphene has an average lateral size of 150-3000 nm. 4. The method of claim 1 , wherein the alcohol is ethanol. 5. The method of claim 1 , wherein the polymer powder is polytetrafluoroethylene. 6. The method of claim 1 , wherein exposing the pressed seal powder comprises soaking the pressed seal powder with the graphene alcohol solution. 7. The method of claim 1 , wherein exposing the pressed seal powder is for 3-5 seconds. 8. The method of claim 1 , wherein, prior to sintering, the alcohol is evaporated. 9. A method of forming a graphene-embedded seal comprising: mixing graphene and alcohol forming a graphene alcohol solution; exposing a polymer seal to the graphene alcohol solution wherein a portion of the graphene alcohol solution infiltrates pores of the polymer seal; and evaporating alcohol from the graphene alcohol solution. 10. The method of claim 9 , wherein the graphene and alcohol solution comprises 0.1-10 mg/L of graphene. 11. The method of claim 10 , wherein the graphene has an average lateral size of 150-3000 nm. 12. The method of claim 9 , wherein the alcohol is ethanol. 13. The method of claim 9 , wherein the polymer seal comprises polytetrafluoroethylene. 14. The method of claim 9 , wherein exposing the polymer seal comprises submerging the polymer seal in the graphene alcohol solution for 5-10 seconds. 15. The method of claim 9 , wherein exposing the polymer seal further comprises applying a vacuum to the polymer seal. 16. The method of claim 9 , wherein exposing the polymer seal further comprises applying a pressure greater than atmospheric to the polymer seal. 17. A method of forming a graphene-embedded seal comprising: mixing graphene and alcohol forming a graphene alcohol solution; exposing a polymeric material to the graphene alcohol solution; and evaporating alcohol from the graphene alcohol solution, depositing graphene within the polymeric material. 18. The method of claim 17 , wherein the polymeric material is a polymer powder. 19. The method of claim 17 , wherein the polymeric material is a polymer seal.
