產(chǎn)品介紹 Product introduction
氟化碳納米管（FCNTs）外觀為粉末狀固體，顏色隨氟碳比提高逐漸由黑變?yōu)榛野?，直至呈現(xiàn)白色。碳納米管（CNTs）自上世紀(jì)90年代被發(fā)現(xiàn)后，受到了人們的廣泛關(guān)注。但是由于CNTs表面的相對惰性，且容易團(tuán)聚纏繞，很難在介質(zhì)中分散，限制了其應(yīng)用，因此對CNTs進(jìn)行表面修飾成為了CNTs 研究領(lǐng)域的熱點(diǎn)。FCNTs一方面保持了其原本的三維管狀結(jié)構(gòu)，另一方面顯著改變了其表面特性、導(dǎo)電性、潤滑性等性質(zhì)，使其可以通過親核取代進(jìn)行進(jìn)一步的表面修飾，這些特點(diǎn)使FCNTs 在鋰電池正極材料、固態(tài)潤滑、復(fù)合物填充劑等領(lǐng)域具有獨(dú)特的用途。采用不同直徑和種類的碳納米管，可以合成具有不同直徑的單壁、少壁及多壁的氟化碳納米管。
Fluorinated carbon nanotubes (FCNTs) are powder solid, and their color gradually changes from black to gray to white with the increasing of F/C ratio. Carbon nanotubes (CNTs) have received a lot of attentions since they were discovered in the 1990s. However, due to the relative inertia of the CNTs surface and the fact that they are easy to agglomerate and difficult to disperse, which limits their applications. Therefore, the surface modification of carbon nanotubes has become a hot research topic in the field of CNTs. On the one hand, FCNTs maintain their original three-dimensional tubular structure; on the other hand, their surface properties are significantly changed, such as conductivity and lubricity, so that surface properties can be further modified by nucleophilic substitution. These characteristics make FCNTs have a unique use in the field of lithium primary battery cathode materials, solid lubrication, composite filling agent and so on. FCNTs are prepared from different diameters and types of carbon nanotubes by fluorination, including single, few and multi-walled FCNTs with different diameters.
產(chǎn)品用途 Application
氟化碳納米管具有獨(dú)特的電化學(xué)特性，在傳感器、電子器件、芯片等領(lǐng)域具有一定的應(yīng)用潛力。另外可通過表面微氟化改性，提高其親水性，改善碳納米管在溶液中的分散性能。
FCNTs have unique electrochemical properties and have potential applications in sensors, electronic devices, chips and other fields. In addition, surface fluorination of carbon nanotubes can be used to improve the hydrophilicity and dispersion of carbon nanotubes in solution.
