Abstract
A method for preparing fluorinated graphene nanoribbons by using fluorine gas as a fluorine source, which includes a step of: fluorinating anhydrous carbon nanotubes in a fluorine gas atmosphere under a pressure of −0.07˜0 MPa and a temperature of 280˜450° C. to obtain the fluorinated graphene nanoribbons. The method provided is operationally simple, and has a wide variety of raw material sources, low cost, and high production which can reach up to tens of milligrams and even up to hundreds of grams; moreover, the method has simple post-treatment, and can produce fluorinated graphene nanoribbons by a one-step reaction. The prepared fluorinated graphene nanoribbons have very good superhydrophobic properties and chemical stability, and thus can be applied to the anti-icing and other fields, having a very good application prospect.
