A facile green approach for the synthesis of amphiphilic SiO2 Janus particles using low temperature atmospheric pressure plasma is reported in this study. Monodispersed SiO2 particles were masked by embedding half of their surface inside a polystyrene film. The exposed surfaces of the SiO2 particles were readily modified using He/CF3CFH2 low-temperature atmospheric pressure plasma to obtain amphiphilic Janus particles. Their amphiphilic nature was confirmed using fluorescent microscopy by tagging their hydrophilic part with a fluorescent dye. The present method can be used to generate amphiphilic Janus particles with a variety of functionalities, which may find applications as surfactants and surface modifying agents.

常压等离子体辅助两亲性SiO 2 Janus粒子的绿色合成

该研究报道了一种利用低温大气压等离子体合成两亲性SiO 2 Janus颗粒的简便绿色方法。通过将单分散的SiO 2颗粒的一半表面嵌入聚苯乙烯薄膜中来掩盖。使用He / CF 3 CFH 2可以轻松地改性SiO 2颗粒的暴露表面低温大气压等离子体获得两亲性Janus粒子。使用荧光显微镜通过用荧光染料标记其亲水部分来证实其两亲性。本发明的方法可用于产生具有多种功能的两亲性Janus颗粒,其可用作表面活性剂和表面改性剂。
