Nano-cellulose interpenetrating Mxene composite material, preparation method and application of nano-cellulose interpenetrating Mxene composite material

The invention belongs to the technical field of fire early warning and flame retardant materials, and relates to a nanocellulose interpenetrating Mxene composite material, a preparation method and application thereof. In order to solve the technical problems that in the prior art, MXene early warning coating materials do not have dependence on resistance and temperature, MXene also has conductivity at normal temperature and low temperature, and MXene cannot respond to the temperature of a fire scene, nanocellulose is interspersed with MXene, and the prepared composite material can block the conductivity of MXene at normal temperature and low temperature. The invention further provides a preparation method of the nanocellulose interpenetrating Mxene composite material and application of the nanocellulose interpenetrating Mxene composite material in preparation of fire early warning wood, the nanocellulose interpenetrating Mxene composite material is applied to wood and the like, an MXene conductive network is
