本研究利用電漿改質技術將馬來酸酐分子分別接枝於單壁及多壁碳管表面；接著，單壁碳管再利用酸酐和胺基反應；最後，利用表面的胺基與液晶小分子4-己基苯甲酸進行接枝反應，用以提升單壁奈米碳管在群創公司液晶中的分散性。奈米碳管上的接枝量經ESCA分析儀器結果顯示量測，單壁奈米碳管表面的液晶小分子接枝量達36.83wt%。將奈米碳管以不同濃度混摻於群創液晶中，未改質的單壁奈米碳管只能維持3天的穩定性，改質後的單壁奈米碳管可以穩定維持達14天。當添加濃度為0.03wt%的改質單壁奈米碳管至液晶溶液時，液晶溶液中的離子濃度下降率達98.32%。光電響應實驗顯示將碳管混摻於液晶中可促使臨界電壓下降，液晶分子反應速度加快，可將液晶反應上升時間由17.28ms降低至14.03ms，下降時間由10.02ms下降至6.132ms。另一方面，將接枝馬來酸酐的多壁碳管分散於NMP溶劑中，加入聚亞醯胺（polyimide, PI）製成具離子吸附功能的配向膜。由AFM掃描，可證明碳管分散於高分子薄膜表面 。將聚亞醯胺－碳管溶液塗佈於ITO玻璃上，並經過摩擦配向組成扭轉向列型液晶盒，並量測其光電性質，可以發現添加碳管之後的確使離子濃度下降，達到液晶分子反應速度加快，降低反應時間的效果。

Single-wall (SWCNT) and multi-walled (MWCNT) carbon nanotubes functionalized with maleic anhydride (MA) by plasma treatment and well dispersed within the Innolux-LC were investigated in this study. In order to improve the dispersion of SWCNT in the liquid crystal solution, the MA modified SWCNT (SWCNT-MA) were further reacted with 4-hexylbenzoic acid. ESCA shows the quantitative analysis about the grafting percent of 4-hexylbenzoic acid on the surface of SWCNTs giving 36.83wt%. The 4-hexylbenzoic acid modified SWCNT-MA (SWCNT-MA-LC) was dispersed well in the Innolux-LC in different concentrations after the stability test. Compare to the pristine SWCNTs which had only 3 days, SWCNT-MA-LC could disperse stable in the solution for 14 days. The results of the electro-optical measurements showed that the ion density of the Innolux-LC was decreased 98.32% when SWCNT-MA-LC was dispersed within the Innolux-LC. Not only the threshold voltage of the Innolux-LC was descended, but the response time of LC was also decreased. The rise-time response of the Innolux-LC was descended from 17.28ms down to 14.03ms and the fall-time response of the Innolux-LC was decreased from 10.02 ms down to 6.132 ms. Moreover, the MWCNTs-MA were directly immobilized in the polyimide to absorbed the ions in the Innolux-LC. After MWCNT was modified by MA (MWCNT-MA), MWCNT-MA was added into the polyimide solution (PI-CNT). PI-CNT solutions were coated on the ITO then rubbed by the alignment machine to construct TN cell. AFM analysis shows that the MWCNT-MA was dispersed on the surface of the polyimide film. By the electro-optical measurement, both the ion density and response time of Innolux-LC were deceased when modified-MWCNT was in the PI.
