Abstract

The invention relates to a preparation method for a conductive timber. The preparation method comprises that (1) a timber sample is directly added into emulsion of a conductive polymeric monomer at a temperature of 1 DEG C to 100 DEG C, initiator is then added, and the temperature is maintained at 1 DEG C to 100 DEG C for a reaction for 1-48 hours after finishing dropping of the initiator; and (2) the timber obtained from the step (1) is taken out, and finally the timber is dried in vacuum at 1 DEG C to 100 DEG C to obtain the conductive timber. The preparation method is simple, has convenience in operation, has not high requirement on equipment, and is suitable for a large scale production. According to the conductive timber, surface decoration effects of natural regeneration, remarkable ratio of strength to weight and nature returning of the timber, as well as excellent environics characteristics of humidity regulation, temperature regulation, sound insulation and the like are maintained, the timber is further provided with conductivity, and the application prospect is broad.

Description

technical field [0001] The invention belongs to the field of preparation of conductive materials, in particular to a method for preparing conductive wood. Background technique [0002] Wood is a widely used biomass energy material. Compared with steel, cement, plastic and other materials, the biggest feature of wood is that it can be naturally regenerated. The reason why wood has been used and loved for a long time is mainly because of its natural material properties and affinity with human beings. [0003] Although wood has been applied in many occasions, its application in some current occasions is limited due to its non-conductivity and no function of shielding electromagnetic waves. For example, in the wall decoration process of hospital operating rooms, important meeting places, theaters, etc., people hope to use wood, but because of its non-conductive properties, people have to further apply other materials for multiple decorations. This not only leads to various wa...
