TH10325Y - Synthesis process of graphene-coated cotton oil absorbent material. - Google Patents

Abstract

New request, updated 24/08/2016. The synthesis process of graphene-coated cotton for use as an oil absorbent material according to this invention begins with the synthesis of graphene oxide nanosheets. The resulting graphene oxide nanosheets are then used in the synthesis process of graphene-coated cotton, which involves the following steps: Cotton wool, cleaned with acetone and distilled water and dried, is immersed in a suspension mixture of graphene oxide and hydrazine hydrate. It is then baked in an oven at a high temperature for a specified time. The resulting product is separated and dried, yielding graphene-coated cotton as an oil absorbent material.

New request, updated 24/08/2016. 1. The synthesis process for graphene-coated cotton involves the following steps: a. Clean cotton wool with acetone and distilled water using an ultrasonic cleaner, then dry it in an oven at 70°C for 24 hours. b. Weigh 12 mg of graphene oxide, add 30 ml of distilled water, and sonicate it using an ultrasonic cleaner for 30 minutes to obtain a graphene oxide suspension. c. Add 2 ml of hydrazine hydrate to the suspension from step b, then immerse the cleaned and dried cotton wool from step a. d. Transfer the suspension and cotton wool to a Teflon bottle and bake in an oven at 90°C for 12 hours. e. Separate the cotton wool from the suspension and dry it in an oven at 110°C to obtain graphene-coated cotton wool, an oil-absorbing material.
