▎ 摘　　要

NOVELTY - Forming a nanofiber, comprises: (a) providing two dimension (2D) materials with charge bearing moieties on its planar surfaces and at its ends; (b) reacting the charge bearing moieties on the planar surfaces with proton donors, proton acceptors, at least partially hydrophobic counter ions 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; and (c) simultaneously reacting the charge bearing moieties at the ends with proton donors, proton acceptors, at least partially hydrophobic counter ions or the second 2D materials with oppositely charge bearing moieties on its planar surfaces and at its ends, and crosslinking the neutralized charge bearing moieties at the ends in order for the 2D materials of step (b) to interact with each other to form the nanofiber. USE - The method is useful for forming nanofiber. ADVANTAGE - None given. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for nanofiber, where the nanofiber is characterized by a solid or semi-hollow cross sectional profile, where the nanofiber is characterized by a layered cross sectional profile of 2D materials curled up and bonded to each other at their planar surfaces and ends, and the 2D materials are selected from graphene, graphene oxide, few-layer transition-metal dichalcogenides or hexagonal boron nitride.
