    摘要:

    在用檸檬酸鈉作還原劑還原氯金酸的基礎(chǔ)上，提出了一種壓電驅(qū)動式脈動微混合可控合成金納米粒子的制備方法。 分析了金納米粒子的合成機理及脈動微混合的工作原理。針對不同的濃度比(Na3C6H5O7:HAuCl4)和脈動混合頻率設(shè)計并開展了相關(guān)金納米粒子可控合成試驗，利用紫外可見分光光度計和透射電子顯微鏡對所得樣品的光學特性、粒子粒徑、粒子偏差及單分散性進行了表征，分析了濃度比和頻率對試驗結(jié)果的影響。試驗結(jié)果表明：利用壓電驅(qū)動式脈動微混合法，通過控制兩相制劑的濃度比和脈動混合頻率，一定程度上可以實現(xiàn)金納米粒子的可控合成。

    Abstract:

    On the basis of using sodium citrate as a reducing agent to reduce chloroauric acid, a synthesis-controlled method of gold nanoparticles is presented by using the pulsed micromixing technology actuated by PZT actuators. The synthesis mechanism of gold nanoparticles and working principle of pulsed micromixing are analysed. According to different concentration ratio (Na3C6H5O7:HAuCl4) and pulsed mixing frequency, the relevant controlled synthesis tests of gold nanoparticles are designed and carried out. The characteristics of obtained specimen including optical properties, particle size, particle deviation and monodispersity are characterized using UV-vis and TEM. The effect of concentration ratio and frequency to the test results is analyzed. The test results show that controlled synthesis of gold nanoparticles can be realized using the pulsed micromixing method based on piezoelectric actuation, by controlling the concentration ratio of two preparations and pulsed mixing frequency.
