Abstract
Consolidated carbon nanotube or graphene yarns and woven sheets are consolidated through the formation of a carbon hinder formed from the dehydration of sucrose. The resulting materials, on a macro-scale are lightweight and of a high specific modulus and/or strength. Sucrose is relatively inexpensive and readily available, and the process is therefore cost-effective.
Claims7
A carbon material, comprising:
- a plurality of microscopic carbon structures that are interconnected to form a sheet or yarn, wherein 40 to 100 percent of the microscopic carbon structures are at least partially aligned with one another;
- a dehydrated sucrose binder formed by subjecting sucrose to a dehydration reaction, the dehydrated sucrose binder dispersed on at least some of the microscopic carbon structures;
- wherein the dehydrated sucrose binder binds adjacent microscopic carbon structures together and maintains alignment of the microscopic carbon structures.
Dependencies are inferred from the claim text.
