“…To improve the mechanical properties of the rubber, the incorporation of fillers or reinforcement agents, including carbon black, silica, clay, rice bran carbon, nano-Fe 3 O 4 , zinc dimethacrylate, and other materials, has been investigated and it was demonstrated to enhance the rubber performance in terms of tear and tensile strength, hardness and degradability. [18][19][20][21][22] However, the reinforcement with such fillers still presents some disadvantages, as the fillers used are not environmentally friendly. Also, the addition of nano-Fe 3 O 4 leads to a decline in the modulus of elongation and tensile strength of the material.…”
