Abstract
A polymeric flexible substrate may be formed from h-BN sheets having a monolayer of hexagonal born nitride interspersed with domains of at least one functionalized material. The functionalized h-BN sheets may be used in various electronic components such as in circuit boards and touch sensors.
Claims19
A sheet comprising a monolayer of hexagonal boron nitride interspersed with domains of at least one functionalized material, wherein the at least one functionalized material has a hexagonal monolayer structure;
- and the sheet has a first planar surface and a second planar surface opposite to the first planar surface, and the domains of the at least one functionalized material are functionalized with a semiconductor material on the first planar surface;
- the sheet further comprises:
- a first electrode film disposed adjacent to the first planar surface of the sheet, wherein the first electrode film is configured to contact the semiconductor material;
- and
- a second electrode film disposed adjacent to the second planar surface of the sheet, wherein the second electrode film is configured to contact the domains of the at least one functionalized material;
- the first electrode film in contact with the semiconductor material and the second electrode film in contact with the domains of the at least one functionalized material define a conductive path from the first electrode film to the second electrode film.
