    Abstract: 本研究利用溶膠-凝膠法製備奈米級的改質二氧化鋯粒子,我們將四丙氧基鋯烷(ZNP)與螯合劑甲基丙烯酸(MA)反應後,再加入硝酸水溶液反應三小時後,製備成奈米級的二氧化鋯微粒,接著加入偶合劑三異丙基矽基丙烯酸酯(MSMA)對二氧化鋯微粒進行表面修飾,最後再補入硝酸水溶液反應三小時,使系統反應更趨完整;其後我們將製作完成之溶膠加入DPHA以及光起始劑1173製作成具有抗靜電性的有機-無機奈米混成塗料。
    This study demonstrated the production of modified nano-zirconia by utilizing the Sol-Gel Process. The nano-zirconia was formed by reaction of zirconium-n-propoxide (ZNP) with chelating agent methacrylic acid (MA) first, followed by addition of nitric acid and reaction for three hours. The formed nano-zirconia was then modified by using coupling agent 3-(trimethoxysilyl) propyl methacrylate (MSMA). Additional nitric acid was finally added and the reaction was allowed to proceed for another 3 hours to assure the completeness of the reaction. The anti-static organic-inorganic nano hybrid coatings were produced from the formed sol by adding DPHA and photoinitator darocure 1173.

    In this research, we used FTIR, dynamic light scattering particle size analyzer and solid-state 29SiNMR to determine the appropriate reaction time and to analyze the chemical bonds; SEM to observe whether aggregation has occurred in the hybrid material ;TGA to examine the effect of inorganic component on the thermal property of the hybrid material.

    In addition, we used the mixture of ZNP, MA and MSMA in different ratios to create a ternary composition diagram. Based on this diagram,we checked the physical properties (adhesion and hardness test) and surface resistivity hybrid materials with various ratios ZNP,MA, and MSMA to find out the most appropriate ratio to produce a hybrid membrane having the best mechanical and anti-static properties.

    The experimental results indicated that modification of nano-zirconia by MSMA has made it possible to distribute properly in the sol and also avoid the physical aggregation during the proportion of nano-hybrid coatings. We have found out the proper ratios from the ternary composition diagram for preparing hybrid materials with good physical properties. The produced coating material has also reached the market standard for static dissipative materials.
