本論文使用四乙氧基矽烷(TEOS)作為無機單體、苯乙烯(Styrene)作為有機單體，在迷你乳液系統中加入緩衝鹽類-碳酸氫鈉(NaHCO3)、共同安定劑-正十六烷(HD)、陰離子界面活性劑(SDS)、起始劑-偶氮二異丁腈(AIBN)，以及矽烷偶合劑-3-(三甲氧基甲硅烷基)丙基丙烯酸酯(3-(Trimethoxysilyl)propyl methacrylate)。添加酸性觸媒(HCl)調整其pH值，促使TEOS做水解、縮合反應，在80 °C的環境下，合成有機-無機的複合型奈米二氧化矽。經過純化、離心等步驟後放入高溫爐中，在空氣下經過鍛燒程序(Calcination)於600 °C環境下燒結8個小時，將有機相全部去除留下無機相。改變其TEOS/Styrene比例及改變偶合劑含量，探討其粒子的各種性質。
並利用動態光散射粒徑分析儀(DLS)、高解析度場發射掃描式電子顯微鏡(SEM)、穿透式電子顯微鏡(TEM)、表面積及孔徑分析儀(BET)分析其粒徑約115至150 nm，比表面積約700 m2/g。以及使用熱重/熱示差分析儀(TGA)，觀察其粒子熱穩定性，微分式掃描熱量分析儀(DSC)，探討其合成時的吸放熱反應。

In this study, we used miniemulsion as the templates, tetraethyl orthosilicate (TEOS) as monomers in inorganic phase, styrene as monomers in organic phase, sodium bicarbonate (NaHCO3) as buffer salt, n-hexadecane (HD) as a costabilizer, sodium dodecyl sulfate (SDS) as a surfactant, azobisisobutyronitrile (AIBN) as a initiator and 3-(Trimethoxysilyl)propyl methacrylate as a coupling agent. An acidic catalyst (HCl) was added to adjust the pH so that TEOS underwent hydrolysis and condensation reactions to synthesize organic-inorganic composite nano-composite silica particles at 80 ℃. The particles were then purified, centrifuged, dried and placed in the furnace for calcination to remove all of the organic substances and only keep the inorganic substances. The properties of the particles were investigated as a function of the ratio of TEOS to Styrene and the amount of the coupling agent. The size and morphology of the particles were analyzed using DLS, SEM, TEM and BET. The particle size was approximately 115 to 150 nm and the surface area was approximately 700 m2/g. The thermal stability of the particles and their exothermic heat release reactions during synthesis were explored using TGA and DSC, respectively.
