Embodiment Construction
[0018] In order to clearly illustrate the technical features of the present solution, the present application will be described in detail below through specific implementation modes.
[0019] First, the diffusion layer is produced as follows:
[0020] S1. Prepare the straw material: take the corn stalk after the corn is mature, remove the outer skin of the corn stalk, take the straw material of the soft part in the center of the corn stalk, and then dry the straw material, and control the water content in the straw material to 10-15wt%;
[0021] S2. forming a suspension: cutting the straw material into long strips, the length of the straw material is 200-1000 μm, then placing it in acetone to form a polar solution, and fully stirring and mixing;
[0022] S3. Mix in functional substances: add SiC particles and carbon oxide materials to the acetone solution and stir thoroughly. The mesh size of ceramic particles and carbon oxide materials is not less than 300 mesh, then add poly...
