Example Embodiment
[0015] Example 1
[0016] (1) Prepare silver nanowires into 1g / L aqueous solution, and then add 1g / L amino-terminated hyperbranched polymer or hydroxyl-terminated hyperbranched polymer aqueous solution, the amino-terminated hyperbranched polymer or the hydroxyl-terminated hyperbranched polymer The volume ratio of the aqueous solution of chemical polymer to the aqueous solution of silver nanowires is 1:1. After 24 hours of uniform stirring and reaction at room temperature, it is washed repeatedly with deionized water and ethanol and dried to obtain amino-terminated hyperbranched polymer modified silver nanowires or hydroxyl terminated. Hyperbranched polymer modified silver nanowires; (2) Weigh a certain amount of chitosan and add it to the 0.5mol / L acetic acid solution and stir for 2h to completely dissolve it to obtain a chitosan solution with a mass fraction of 1%. Then slowly pour the chitosan solution into a petri dish, air-dry and peel off gently to obtain a chitosan film; (3...
