Embodiment approach
[0060] According to the present invention, the preparation method of the conductive silicone elastomer based on MXene, a kind of preferred embodiment, comprises steps as follows:
[0061] Disperse UPy-NCO and amino functionalized polysiloxane derivative A in dichloromethane, react at 50°C-70°C for 12-24h, after the reaction is completed, add carboxylic acids containing disulfide bonds to derivate Compound B was reacted at 50°C-70°C for 6-12h to obtain polysiloxane derivative C containing multiple reversible bonds; disperse MXenesE and carboxyl-containing L-citrulline D in deionized water, React for 12 to 24 hours, wash 5 times with a high-speed centrifuge to obtain the modified MXenesF; ultrasonically disperse the modified MXenesF into the organosilicon polymer network of polysiloxane derivative C containing multiple reversible bonds, stir and ultrasonically The reaction was shaken for 1 hour, and then solidified to form a film, and the MXene-based conductive silicone elastome...
Embodiment 1
[0077] 0.16 g of UPy-NCO and 10 g of branched polydimethylaminosiloxane (Mn: 2000) were mixed in a three-necked flask. The temperature was raised to 70°C, and the reaction time was 16h. 0.84g of 2,2'-dithiodibenzoic acid was added to the reactant, and the reaction continued for 4h. After the reaction is completed, the product is poured into a polytetrafluoroethylene mold and placed in a vacuum drying oven at 40°C until constant weight to obtain polysiloxane containing disulfide bonds and multiple hydrogen bonds. 1gMXenes (multilayer Ti 3 C 2 ) was dispersed in 15 ml of deionized solution to obtain a suspension. 0.3g L-citrulline, multilayer Ti 3 C 2 The suspension was added to a 50ml three-necked flask equipped with a reflux device and a stirrer and mixed uniformly at 100°C. After 12 hours of reaction, the modified multilayer Ti 3 C 2 . 10g of polysiloxane containing disulfide bonds and multiple hydrogen bonds was mixed with 1g of modified multilayer Ti 3 C 2 Ultraso...
Embodiment 2
[0082] The procedure described in Example 1 was repeated, except that 0.84 g of 2,2'-dithiodibenzoic acid was replaced by 0.46 g of 2,2'-dithiodipropionic acid.
