Dendritic polymer material has the following characteristics: ① unique interpenetrating networks; ② forced mutual capacitance; ③ interpenetrating interface and synergies, etc. Based on these characteristics, after adding dendrimer material, the maximum tensile strength increased 3.36 times to 2. 3MPa compared with the blank film , maximum elongation rate increased 3.69 times to 1860%; when dendrimers(CYD-CR236/CYD-CR486/CYD-CV236/CYD-CV486) content is 20%, the mechanical properties reaches maximum value, the particle size is about 1μm, interpenetrating polymer networks achieves optimal synergy.
