紫外光照射(UV-cured)技術用於合成高分子材料,具有低功耗、時間短與不需要溶劑等優點。適用於紫外光照射的高分子材料被應用於不同的特殊領域與不同的工業領域,儘管已經有許多針對熱成型高分子的研究,但針對紫外光照射高分子的奈米複合材料,其研究卻十分稀少。本研究提出一個新穎、便宜且容易處理的方法,以數位可見光快速原型機來合成丙烯酸酯系光硬化樹脂/無機(clay and BaTiO3)奈米複合材料。這種製程以一次一層的方法將光硬化樹脂奈米複合材料由液體轉變為固體,再藉由一層一層堆疊的方式將樣品製作出來,製作出的樣品將會被測試其機械性質、熱性質、與電性質。其中機械性質的測試包括:利用肖式D型硬度計測試樣品硬度、萬能拉深測試機測試拉伸強度、動態機械分析儀測試彈性模數與儲存模數,熱性質則分別藉由熱重分析儀(TGA);在電性質方面,利用半導體裝置分析儀(Agilent B1500A)於1 M赫茲、電壓從-5到5伏特,量測其介電常數,利用多功能量表(Fluke 117)量測其電阻率。藉由多種特性實驗證實,本研究所製作之光硬化樹脂/無機奈米複合材料適合應用於多種範圍,特別適合於快速原性技術上,此外,也適合運用在相關的應用上,例如:高溫、隔熱、絕緣塗佈、薄膜基材與嵌入式介電材料。
There are some advantages of UV-cured technology process to synthesize the polymer materials such as low energy consuming, short time processes and solvent-free. These have been promoting UV-curable polymer materials become increasingly applied in various scientific and industrial fields. While a lot of studies have been done on thermal curable polymer systems, but only few have focused on preparation of UV-curable polymer nanocomposites. In this research, we propose a novel, cheap and easy handling method to synthesize acrylate-based photopolymer/inorganic (clay and BaTiO3) nanocomposite by using Digital (visible) Light Rapid Prototyping (DLRP) machine. This preparation method provides layer by layer curing process of photopolymer nanocomposite from liquid to solid resulting a layered structure of cured-prototype. The resulted sample then examined its mechanical, thermal, and its electrical properties. The mechanical properties including hardness, tensile strength, modulus elasticity and storage modulus will be examined by using hardness tester type shore D and universal tensile machine, and dynamic mechanical analyzer, respectively. The degradation temperature will be examined by using thermal gravimetric analyzer (TGA). The electric properties such as dielectric constant and resistivity will be examined by using Agilent B1500A Semiconductor Device Analyzer at 1 MHz and -5 to 5 volt and Fluke 117 multimeter respectively. The prototype of photopolymer/inorganic nanocomposite resulted by this method in accordance with several reliable properties is expected to be feasibly applied in several applications especially on Rapid Prototyping Technology and it will also feasible to be applied in related application such as a special part that subjected to heat, thermal barrier, electrical or electronic insulator or coating, film substrates, and embedded dielectric materials.
