Patent number: 8828173Abstract: Reversibly and irreversibly-linking amino-polysiloxanes, methods of making such amino-polysiloxanes, and systems and methods of using such amino-polysiloxanes for the containment and/or remediation of a release and/or spill of a crude oil, a petroleum product and/or a chemical is described. Gels and/or emulsions formed from the combination and/or contacting of such an amino-polysiloxane with these materials can be used to recover these oils or chemicals while allowing the amino-polysiloxane to be recovered and reused to clean up or contain additional materials. Such amino-polysiloxanes can be used as well for the selective uptake of one component of liquid mixtures when such mixtures contain more and less lipophilic components. Methods of making and using adhesive and sealants containing such amino-polysiloxanes are described.Type: GrantFiled: March 22, 2011Date of Patent: September 9, 2014Assignee: Georgetown UniversityInventors: Richard G Weiss, Tao Yu, Koji Wakuda
