NOVELTY - Changing (m1) the conformation of a nanomaterial electrolyte comprises: (a) providing a nanomaterial electrolyte in an aqueous medium to provide a mixture having a first state; and (b) subjecting the mixture to a change of at least one of the pH, ionic strength, temperature, pressure, sonication, and light to provide a mixture in a second state, where the first state of the mixture corresponds to the nanomaterial electrolyte predominantly is in a flat two-dimensional conformation or a scrolled one-dimensional conformation, and the second state of the mixture corresponds to the nanomaterial electrolyte predominantly is in the opposite conformation to the first state, so that if the nanomaterial electrolyte is predominantly in a flat two-dimensional conformation in the first state, it is now predominantly in a scrolled one-dimensional conformation in the second state, or vice versa, and the nanomaterial electrolyte comprises a modified two-dimensional nanomaterial having a surface. USE - The method is useful for changing the conformation of a nanomaterial electrolyte which is used in a drug delivery device (claimed). ADVANTAGE - The method: improves the yield of the reactions; does not require large variations of temperature or the use of solvents to effect a reversible morphological transition; is simple, reversible, environmentally friendly, and template and solvent-free; and allows the two-dimensional electrolytes to expand their use in a wide range of applications, from batteries and sensors to drug delivery systems. DETAILED DESCRIPTION - Changing (m1) the conformation of a nanomaterial electrolyte comprises: (a) providing a nanomaterial electrolyte in an aqueous medium to provide a mixture having a first state; and (b) subjecting the mixture to a change of at least one of the pH, ionic strength, temperature, pressure, sonication, and light to provide a mixture in a second state, where the first state of the mixture corresponds to the nanomaterial electrolyte predominantly is in a flat two-dimensional conformation or a scrolled one-dimensional conformation, and the second state of the mixture corresponds to the nanomaterial electrolyte predominantly is in the opposite conformation to the first state, so that if the nanomaterial electrolyte is predominantly in a flat two-dimensional conformation in the first state, it is now predominantly in a scrolled one-dimensional conformation in the second state, or vice versa, the nanomaterial electrolyte comprises a modified two-dimensional nanomaterial having a surface, the surface is modified by many functional groups comprising at least one of comprising imine, sulfonic acid, sulfonamide, amine, hydroxy, carboxylic acid, thiol, and amide on the surface of the modified two-dimensional nanomaterial, the nanomaterial electrolyte is capable of reversibly adopting a flat two-dimensional conformation or a scrolled one-dimensional conformation upon a change to its ambient environment, the change in the ambient environment is due to a change of at least one of the pH, ionic strength, temperature, pressure, sonication, and light in the ambient environment, and the quantity of the functional groups is greater than that present in an unmodified form of the same two-dimensional nanomaterial. INDEPENDENT CLAIMS are also included for: (1) a nanomaterial electrolyte comprising a modified two-dimensional nanomaterial having a surface; (2) forming (m2) the nanomaterial electrolyte comprising (i) providing an unmodified two-dimensional nanomaterial, and (ii) reacting it with at least one functionalising reagents in the presence of a solvent to provide a nanomaterial electrolyte; and (3) a drug delivery device comprising a nanomaterial electrolyte, and a drug attached to a surface of the nanomaterial electrolyte, where the nanomaterial electrolyte is provided in a scrolled one-dimensional conformation, so that the drug is encapsulated within an interior of the scrolled one-dimensional confirmation and is released when the nanomaterial electrolyte adopts a flat two-dimensional conformation upon exposure to an acidic or a basic environment.
