Abstract
In one embodiment, a method for producing a graphene-containing composition is provided, the method comprising: (i) mixing a graphene oxide with a medium to form a mixture; and (ii) heating the mixture to a temperature above about 40° C., whereby a graphene-containing composition is formed from the mixture. Composites of polymers with disperse functionalized graphene sheets and the applications thereof are also described.
Claims27
A method for producing a graphene-containing composition, comprising:
- (i) mixing graphene oxide with a medium to form a mixture, wherein the medium comprises a solid or a precursor thereof;
- and
- (ii) heating the mixture to a temperature above about 40° C., whereby a graphene-containing composition is formed from the mixture.
A heat sensor, comprising a graphene oxide and a medium, wherein at least some of the graphene oxide is transformed into at least one of (i) graphene and (ii) graphene oxide with a smaller amount of functional groups when the heat sensor is exposed to an energy source.
A method of modifying a property of a material, comprising:
- (i) introducing graphene oxide to a material;
- and then
- (ii) heating the material at a temperature sufficiently high to promote transformation of at least some of the graphene oxide, whereby a property of the material is modified via the transformation.
