Based on the green synthesis technology of"thiol-ene"click chemistry,a new POSS multifunctional nanohybrid material was prepared by a simple one-step method,which showed good binding with the new tobacco,was easy to form a film on the surface,and achieved the difunctional properties(deliquescence proof capability and moisture-retaining property)of the new tobacco effectively after modification.The chemical structure of the prepared composites was characterized using nuclear magnetic resonance and infrared spectroscopy,and the deliquescence proof capability and moisture-retaining property of the modified new tobacco were investigated in detail under different humidity.The mechanism was investigated in detail based on these studies of material solubility,surface tension,contact angle,etc.The influence of the structure of the material on the material performance was explored in-depth.The results show that the prepared compounds can significantly improve the deliquescence proof capability of tobacco particles in high humidity(RH=80%)and moisture-retaining property in low humidity(RH=30%)environments.This study provides new inspiration,theoretical and experimental basis for the design of new multifunctional materials for development of new tobacco.
