NOVELTY - Preparing nano carrier material involves mixing nano cellulose solution and graphene, crushing, subjecting to ultrasonic for 3-10 minutes, mixing uniformly to obtain nano cellulose/graphene suspension, mixing nano cellulose/graphene suspension with phenolic resin, stirring with 80-400 revolution per minute speed for 10-30 minutes to obtain nano cellulose/graphite/phenolic resin suspension. The nano cellulose/graphite/phenolic resin suspension is molded, placed in freezer dryer for freezing at (-)40-(-)60 degrees C for 8-15 hours. USE - Method for preparing nano carrier material (claimed). ADVANTAGE - The method enables to prepare nano carrier material that is convenient to use, has strong waterproof performance, high mechanical property, good application prospect, high intensity and network structure, and in simple, and cost effective manner. DETAILED DESCRIPTION - Preparing nano carrier material involves mixing nano cellulose solution and graphene, crushing, subjecting to ultrasonic for 3-10 minutes, mixing uniformly to obtain nano cellulose/graphene suspension, mixing nano cellulose/graphene suspension with phenolic resin, stirring with 80-400 revolution per minute speed for 10-30 minutes to obtain nano cellulose/graphite/phenolic resin suspension. The nano cellulose/graphite/phenolic resin suspension is molded, placed in freezer dryer for freezing at (-)40-(-)60 degrees C for 8-15 hours. The freezed product is dried at 10-40 degrees C for 5-8 hours in vacuum, and demolded to obtain nano cellulose/graphite/phenolic resin gas gel. The nano cellulose/graphite/phenolic resin gas gel is placed in muffle furnace for preheating for 10-30 minutes. The phenolic resin gas gel is completely solidified, treated and cured. The nano cellulose/graphite/phenolic resin gas gel is subjected to high temperature thermal decomposition treatment after carbonization in the tubular furnace to obtain nano carrier material.
