Abrégé

A method of manufacturing a carbon nanostructure, such as a carbon foam material, is disclosed. The method comprises the steps of: (a) using a first laser beam to irradiate an encapsulated or sub-surface region of a carbon pre-cursor material below a surface of the material, to create carbon foam in that sub-surface region, and a disorganised, amorphous non-graphene material above the carbon foam, and then (b) using a second laser beam to remove or ablate the disorganised, amorphous non-graphene material sitting above the carbon foam, to expose at least some of the carbon foam. The resultant carbon foam material shows a significant D peak; the 2D peak is significantly less than the G peak; and the peak D: peak G ratio is significantly above zero. In appearance and Raman signature, it appears similar to a carbon nano-onion material. It can be used in biosensors, supercapacitors and pseudo-capacitors.

A triboelectric nanogenerator (TENG) uses a carbon foam based electropositive layer The carbon foam is made using a dual laser process in which: (a) a first laser beam irradiates an encapsulated, sub-surface region of a carbon pre-cursor material below a surface of the carbon pre-cursor material, to create carbon foam in that encapsulated, sub-surface region, and then (b) a second laser beam (i) removes or ablates material sitting above the carbon foam, and (ii) exposes the carbon foam and thereby produce the resultant carbon foam material that is used as the electropositive layer in the TENG.

A method of manufacturing a component for an atomising device is disclosed; the component is made substantially of carbon foam. The method includes the step of using a high temperature process generated by a laser beam directed at a carbon-based pre-cursor material, such as a polymer or polyimide sheet material, to manufacture the carbon foam component. The component is electrically conductive, non-metallic and porous to e-liquid. The component can be a carbon foam based component that functions as both a wicking element and also a heating element.
