  • Publication number: 20240376016
    Abstract: The present disclosure concerns nanofibers and methods of forming these nanofibers thereof. The method of forming nanofiber comprises providing 2D materials with charge bearing moieties on its planar surfaces and at its ends, reacting the charge bearing moieties on the planar surfaces with proton donors, proton acceptors, at least partially hydrophobic counterions or a second 2D materials with oppositely charge bearing moieties on its planar surfaces and at its ends in order to curl the 2D material, simultaneously reacting the charge bearing moieties at the ends with proton donors, proton acceptors, at least partially hydrophobic counterions or the second 2D materials with oppositely charge bearing moieties on its planar surfaces and at its ends, and crosslinking the neutralised charge bearing moieties at the ends in order for the 2D materials to interact with each other to form the nanofiber.

  • Publication number: 20240025750
    Abstract: Disclosed herein is a nanomaterial electrolyte formed from a modified two-dimensional nanomaterial having a surface, where the surface is modified by a plurality of functional groups selected from one or more of the group consisting of imine, sulfonic acid, sulfonamide, amine, hydroxyl, carboxylic acid, thiol, and amide on the surface of the modified two-dimensional nanomaterial, where the nanomaterial electrolyte is capable of reversibly adopting a flat two-dimensional conformation or a scrolled 1-dimensional conformation upon a change to its ambient environment. There is also disclosed a method of effecting a change in conformation from one form to the other (and back again).
