Abstract

Official abstract text for this publication.

The present invention provides certain chemical compounds or materials having adhesive properties or functionality that act as adhesives or sealants in a variety of applications. In particular, the invention, including its various embodiments, relates to certain functional graphenic materials having an attached adhesive moiety that provides adhesive properties or functionality to the resulting compound and that can be used as an adhesive or sealant in a variety of applications, such as in-situ repair of a leak or defect in a tube carrying a fluid, such as a condenser tube in a power plant.

First claim

Opening claim text (preview).

What is claimed is: 1. A seal in an opening in a tube wall, comprising: an opening in a tube wall; a seal comprising a graphenic scaffold having a covalently attached molecule a catechol or catechol derivative, wherein said seal is adhered to a portion of said tube wall thereby covering said opening. 2. The seal of claim 1 , wherein said graphenic scaffold comprises graphene oxide. 3. The seal of claim 1 , wherein said graphenic scaffold comprises Claisen Graphene. 4. The seal of claim 1 , wherein said catechol comprises 1,2-dihydroxybenzene. 5. The seal of claim 1 , wherein said catechol derivative comprises a catecholamine. 6. A method for reducing a leak in a tube, comprising: adding a sealant to a fluid passing through a tube, wherein said sealant comprises a graphenic scaffold having a covalently attached molecule a catechol or catechol derivative and wherein said tube comprises a leak through which said fluid is passing; adhering said sealant to said tube adjacent to said leak; and forming a seal comprising said sealant, thereby covering said leak. 7. The method of claim 6 , wherein said graphenic scaffold comprises graphene oxide. 8. The method of claim 6 , wherein said graphenic scaffold comprises Claisen Graphene. 9. The method of claim 6 , wherein said catechol comprises 1 , 2 - dihydroxybenzene. 10. The method of claim 6 , wherein said catechol derivative comprises a catecholamine. 11. The method of claim 6 , wherein said forming comprises preventing said fluid from passing through the leak. 12. The seal of claim 5 , wherein said catecholamine comprises 3,4-dihydroxybenzylamine. 13. The seal of claim 10 , wherein said catecholamine comprises 3,4-dihydroxybenzylamine.
