A method of recycling a polymer structure includes converting a first polymer structure into feedstock. The first polymer structure comprises particles that are bonded to one another by chemical click bonds to form a first shape. The first polymer structure is converted into feedstock particles by breaking the click bonds. The feedstock particles are formed into a second shape, and the feedstock particles are chemically click-bonded together to form a second polymer structure having a second shape. Breaking the click bonds may include heating the particles. The structures may be formed by causing first particles having dienes to chemically bond to dienophiles of second particles.

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&#xb0; 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.
