Abstract: Composite antibacterial material was prepared by doping acid-treated sepiolite with ionic liquid （tetradecyl-3-methylimidazole bromide）. X-ray diffraction （XRD）, thermogravimetric analysis （TG） and scanning electron microscope （SEM） methods were employed to analyze the dispersion state of ionic liquid in sepiolite. The antibacterial abilities of the as-prepared materials were investigated with E.coli （gram-negative） and B. paramycoides （gram-positive） used as target strain. The results show that ionic liquid finely disperses in the micro-pore of sepiolite and exhibites good thermal stability which makes it a promising material to be used in heat-resisting coating to give rise to antibacterial ability.
