奈米級複合材料(nanocomposites)已是現今二十一世紀最為熱門的產業之一,所謂奈米級複合材料為分散相粒徑介於1nm~100nm之複合材料,他可充分發揮量子尺度之介觀結構特性,如粒徑小、高視徑比、層狀補強結構、離子鍵結、表面與介面效應、巨觀量子穿隧效應等性質,介於次微米結構特性;使物質的化學與物理性質產生非常重大的改變。本研究中主要利用ZrOCl2.?8H2O分別與Vinylphosphonic acid (VPA)與H3330PL反應生成含磷酸鋯衍生物並且帶有~C=C官能基,其中磷酸鋯為主要層狀無機結構物的組成,而此磷酸根之衍生物為帶有~C=C官能基並暴露在層狀結構的表層,另外藉由XRD、SEM、TGA、FT-IR...等對其結構加以鑑定。 另外又將本研究中所合成的人工層狀材料加入環氧樹脂中,進行開環反應,得到有機/無機奈米複材,並探討其在高分子中的性質。首先利用膠化實驗探討其反應性,再藉由XRD、TEM...等加以鑑定其在高分子中的分散情形,並利用TGA、DSC...等儀器探討其熱性質,由於本層狀材料含磷、鋯等無機物,因此也對其抑制燃燒的特性做LOI的檢測,最後利用UV-Vis來檢測其透明度。
The nanocomposites is one of the most popular industries in 21st century in the world . The nanocomposites mean that it composites of more than one Gibbsian solid phase where at least one dimension is in the nano – meter range and typically all solid phase are in 1-20nm range. In our study we preparation of zirconium phosphate/phosphonate derivatives (ZrP) with the functional of vinyl group (~C=C) . The layers consist of metal atoms (Zr) lying slightly above and below the mean plane and bridged by phosphate groups from above and below the plane. The layered inorganic materials, zirconium phosphate/phosphonate derivatives, were hybrid with the epoxy to synthesize the organic/inorganic nanocomposites. The XRD and TEM show the inorganic materials dispersed in the polymer materials well. The results of the TGA and DSC indicate the thermal properties of the nanocomposites . The flame-retardant properties were examined by the limiting oxygen index (LOI), and the transparency was measured by the UV-Visible spectrophotometer.
