Abstract:In this study， the bamboo cellulose was employed to construct the network backbone of conductive gel， thus forming the composite cellulose ionic gels （CCIGel） by adding the metal salt ions. The results showed that ZnCl2， CaCl2 and FeCl3 could lead to the formation of CCIGel， and the mechanical properties of both CCIGel-Zn and CCIGel-Ca were stronger than CCIGel-None， while the system with the addition of AlCl3 could not form the ion gel. The CCIGel-Zn with 15% ZnCl2 had the most excellent performance with the tensile strength of 1.344 MPa， toughness of 29.85 MJ/m3， ionic conductivity of 47.1 mS/cm and the transmittance of 86.9%， respectively.
