%X Fullerene C60 whiskers (FWs) doped with polyaniline emeraldine base (PANI-EB) were synthesized by mixing PANI-EB/N-methyl pyrrolidone (NMP) colloid and FWs suspension based on the nature of the electron acceptor of C60 and electron donor of PANI-EB. Scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), and ultraviolet-visible (UV-Vis) spectra characterized the morphology and molecular structure of the FWs doped with PANI-EB. SEM observation showed that the smooth surface of FWs was changed to worm-like surface morphology after being doped with PANI-EB. The UV-Vis spectra suggested that charge-transfer (CT) complex of C60 and PANI-EB was formed as PANI- - . PANI-EB-doped FWs might be useful as a new type of antibacterial and self-cleaning agent as well as multifunctional material to improve the human health and living environment. 1. Introduction Since the discovery of fullerenes (including buckminsterfullerene, C60), the physical and chemical properties of this new allotropic carbon form have been investigated extensively [1¨C3]. Recently, fullerene nanocrystal which is constructed by fullerene C60 attracts many researchersĄŻ attention, because those special crystals not only own the property of fullerene C60 such as the nature of electron acceptor but also get the special dimension effect [4¨C8]. Fullerene C60 whiskers (FWs), among the crystals, catch special attentions and are widely studied in many fields, recognized its potential applications in solar cells, [9] catalysts carriers [10, 11], and so on. Quite recently, FWs have been studied together with other materials. For example, the embedment of potassium atom in fullerene cage could increase the conductivity of FWs dramatically [12]. In biochemical field, joint research of FWs and DNA exhibits potential bioanalytical applications [13]. Polyaniline (PANI), as a conducting polymer, has great potential for modification of molecular structure, undergoes a special proton doping mechanism, and has got enormous attentions since the early 1980s [14]. Excellent antibacterial performance of PANI against Escherichia coli and Gram-positive Staphylococcus aureus microorganisms has been demonstrated under both dark and visible light conditions [15]. The electrostatic adherence interaction between the PANI molecules and the bacteria may play a very important role in the antibacterial reaction of the PANI. And in this perspective, FWs which are in micron scale could be used in preparing composites materials with large specific surface areas and micron dispersion with better antibacterial effect.
