Abstract The chitosan (CS) rods were reinforced by thermal cross-linking method through microwave irradiation. The results show that the rotary viscosity of CS solution was increased due to thermal cross-linking reaction, but much more irradiation time would decrease its solution viscosity because of thermal decomposition. Crystallinity of CS was reduced due to the formation of network structure. Bending strength and bending modulus of microwave irradiated CS rods maximized at 182.8 MPa and 5.6 GPa, increased by 97.8% and 36.6% respectively, compared with untreated CS rods. The improvement of mechanical properties can be
attributed to the formation of network structure.
