Method for preparing boron nitride nanosheets, method for preparing boron nitride nanosheet-based fibers, and fibers prepared thereby

Abstract

A method for manufacturing boron nitride nanosheets, a method for manufacturing boron nitride nanosheet-based fibers, and fibers manufactured thereby are provided. In the method for manufacturing boron nitride nanosheet-based fibers, a radical initiator is added to boron nitride nanosheets (BNNS) for a solvothermal reaction under basic conditions to form hydroxyl-functionalized BNNS (o-BNNS). The o-BNNS is then dispersed and centrifuged to prepare a liquid crystalline boron nitride dope solution, which is subsequently wet-spun and dried. This process enables the facile production of fibers characterized by high mechanical strength, improved thermal conductivity, and superior electrical insulation.
