Abstract: In various exemplary embodiments, the present disclosure provides a process for the conversion of certain polymers into diamond and diamond-like materials using laser pulse annealing. The process includes transforming the polymer to carbon, melting the carbon and quenching the carbon melt into to form Q-carbon, diamond, and/or graphene. The process can be applied to a polymer film such as a polytetrafluoroethylene (PTFE) tape. An object can be coated with the polymer film which can then be converted to Q-carbon, diamond, and/or graphene using laser pulse annealing. A process is also provided for making a three-dimensional object using a combination of, for example, 3D printing the polymer and converting each layer of polymer into Q-carbon, diamond and/or graphene.
