Claim Text:
1. A method of making non-covalently bonded carbon-titania nanocomposite thin films, comprising: forming a carbon-based ink; forming a titania (TiO blade-coating a mechanical mixture of the carbon-based ink and the titania solution onto a substrate; and annealing the blade-coated substrate at a first temperature for a first period of time to obtain the carbon-based titania nanocomposite thin films, wherein the carbon-based ink comprises a concentrated solvent-exfoliated graphene (SEG) ink; and wherein the forming of the concentrated SEG ink comprises: adding a first amount of natural graphite to a second amount of N,N-dimethylforamide (DMF) to form a first graphite solution; sonicating the first graphite solution at a first frequency for a second period of time; centrifuging the sonicated first graphite solution for a third period of time at a first rotation speed to obtain a SEG supernatant; and disposing the SEG supernatant in ethyl-cellulose (EC) and terpineol, and evaporating the DMF in the SEG solution to form the concentrated SEG ink.
