研究目的
To study the influence of the nature and structure of surfactants, and also of the reaction medium on the size of tin dioxide nanoparticles obtained by the reverse micelle method.
研究成果
The study demonstrated that electrostatic interactions inside a drop stabilized by surfactants significantly affect the morphologic parameters of tin dioxide nanoparticles obtained by the reverse micelle method.
研究不足
The study highlights the difficulty in adjusting particle size due to the fast reaction of tin tetrachloride hydrolysis and the complexity in choosing process parameters for nanoparticle size adjustment.
1：Experimental Design and Method Selection:
The study involved synthetic and computational experiments to investigate the effect of surfactants and reaction medium on tin dioxide nanoparticle size.
2：Sample Selection and Data Sources:
Nanoparticles were synthesized in a water–nonpolar hydrocarbon solvent system using surfactants of various chemical natures.
3：List of Experimental Equipment and Materials:
Included a magnetic stirrer, sonicator, spin dryer, X-ray diffractometer (Bruker 'D2 Phaser'), and transmission electronic microscopy.
4：Experimental Procedures and Operational Workflow:
Initial reagents were added dropwise to the system, followed by maintenance, separation, washing, and drying.
5：Data Analysis Methods:
X-ray phase analysis, transmission electronic microscopy, and Brunauer–Emmett–Teller method were used for nanoparticle size determination.
