A high-strength network structured nano-carrier material and a preparation method and application thereof. A nano-cellulose solution and graphene are mixed and ultrasonication is performed in an ultrasonic pulverizer to obtain a nano-cellulose/graphene suspension. The suspension with a phenolic resin adhesive is mixed and stirred to obtain a nano-cellulose/graphene/phenolic resin suspension. The nano-cellulose/graphene/phenolic resin suspension is injected into a mold. The mold is placed in a freeze dryer for freezing and vacuum dried in two stages to obtain a nano-cellulose/graphene/phenolic resin aerogel. The aerogel is preheated and cured in a muffle furnace, then subjected to a high-temperature thermal decomposition treatment in a tube furnace to obtain a nano-carrier material having a high-strength network structure. The preparation method is simple and convenient, low in cost, environmentally friendly and green. The obtained carrier material has a good water resistance and a high mechanical property, and can carry more active substances.
A method for preparing a high-strength network structured nano-carrier material, comprising steps of:
A high-strength network structured nano-carrier material having a density of 3.05-3.70 g/m2 and a pore diameter of 0.02-5 μm;
