To improve the dispersion ability of CuO nanoparticles (NPs), their surface was modified by chiral diacids (DAs) containing amino acids. The surface modification process was achieved using ultrasonic irradiation. DA could be absorbed on the surface of CuO. The carboxyl groups of DA may interact with surface of CuO NPs and form covalent bond with it. Interactions between DAs and CuO NPs were investigated
为了提高CuO纳米颗粒(NPs)的分散能力,其表面被含有
氨基酸的手性二酸(
DAs)改性。使用超声波辐照实现了表面改性过程。
DA可以被吸收在CuO的表面上。
DA的羧基可与CuO NP的表面相互作用并与其形成共价键。通过不同的技术研究了
DA与CuO NP之间的相互作用。X射线衍射图证明,改性过程不会改变CuO的晶相。结果证实了有机官能团在NP表面上的成功沉积。
