A low temperature carbonizable material and the method for making the same, wherein polyester polymer material, biomass material, and phosphorous catalyst are used as raw materials for making low temperature carbonization material, the phosphorous catalyst catalyzes polyester polymer fracture to produce alcohol group and acid group, which forms a catalytic chain reaction to further catalyze the carbonization reaction of the biomass material. Besides, the catalytic chain reaction can also effectively lower the carbonization temperature, which allows the carbonization process to be completed within 30 minutes at a temperature of 170 to 250° C., and the obtained product can be more easily processed into desired shaped or pressed into films.
