Zusammenfassung:	The invention relates to an LG-CTAB-Citral microcapsule and a preparation method thereof, the LG-CTAB-Citral microcapsule is applied to an antibacterial composite aerogel filter disc, the LG-CTAB-Citral microcapsule is added into a CNF suspension, then a poly MTMS solution is added, a CNF/MTMS/LG-CTAB-Citral mixed suspension is prepared, and the CNF/MTMS/LG-CTAB-Citral mixed suspension is pre-frozen with liquid nitrogen or an ultralow-temperature refrigerator; the CNF/MTMS/LG-CTAB-Citral antibacterial aerogel filter disc is obtained by adopting a freeze drying process, and the invention aims to provide a novel antibacterial filter disc with the filtering efficiency of 95-99.9% and the antibacterial rate of 80-95%. By adding the LG-CTAB-Citral microcapsules, separation of microfibers is promoted, the aerogel sheet also presents a relatively uniform network pore structure, the pressure drop of a filter disc is reduced, and the defect of poor filtering efficiency of single CNF aerogel is improved through the syn
