| 摘 要：作為優(yōu)良的導電聚合物，聚苯胺（PANI）在許多行業(yè)有廣泛的應用。作為一種無(wú)機材料，二氧化鈦（TiO2）在諸多領(lǐng)域也有應用潛力。但PANI和TiO2難以滿(mǎn)足較高性能的要求，利用PANI修飾TiO2制備二元納米復合材料或者再摻雜其他材料合成三元甚至多元納米復合材料，依靠形成的p-n結異質(zhì)結構和材料間的協(xié)同效應獲得獨特性能復合材料成為近年來(lái)研發(fā)的熱點(diǎn)。介紹了PANI/TiO2復合材料的主要制備方法如原位聚合法、相轉化法、水熱法、浸漬法、電化學(xué)法等，概述了其在光催化劑、傳感器、吸附劑、電極、吸波、防腐等方面的應用研究進(jìn)展，提出了目前還存在的問(wèn)題，并對未來(lái)的研究方向進(jìn)行了展望。 |

| Abstract：As one kind of excellent conducting polymer, polyaniline (PANI) has a wide range of applications in many industries. As inorganic material, titanium dioxide (TiO2) has certain application potential in many fields. However, the PANI and TiO2 cannot meet the requirements of high performance. TiO2 modified by PANI is used to prepare binary nanocomposite or doped with other materials to synthesize ternary and even multi-component nanocomposite, which has become a hot topic of research in recent years. The composites can obtain unique properties by relying on the formed p-n heterostructure and the synergistic effect between materials. The main preparation methods of PANI/TiO2 composites, such as in situ polymerization, phase inversion, hydrothermal method, impregnation method, electrochemical method are summarized. The research progress of its application in photocatalyst, sensor, adsorbent, electrode, wave absorption, corrosion protection and so on is introduced. The existing problems are pointed out and the future research directions are prospected. |
