摘　　要：农药的减量增效是近年来农药领域的关键问题,使用纳米载体技术将农药制成纳米农药为解决这一难题提供了新思路。不同于大多数基于热力学平衡组装的纳米载体技术,新兴的瞬时纳米沉淀法基于动力学控制原理、通过化学工程上的流体湍流混合方式制备纳米材料。这种方法不仅具有载药率高、制备时间短、易于放大与连续化生产等特点,还可以系统地调控纳米微观结构,如形貌、内部结构、表面结构等,为纳米材料在农药领域进一步的高效和低毒利用提供帮助。本文综述了瞬时纳米沉淀法在纳米结构调控及农业上的应用。The pesticide reducing has been a key issue in pesticide areas in recent years.The use of nano-carrier technology to incorporate pesticides into nanoparticles provides a new route for solving the problem.Different from most nano-carrier technologies which are based on thermodynamic equilibrium self-assembly,the emerging Flash Nanoprecipitation(FNP)method is based on kinetic control,preparing nanoparticles through turbulent mixing of chemical engineering fluids.It has advantages like high drug loading efficiency,short preparation time(milliseconds),easy to scale-up and continuously production,etc.Moreover,it can also systematically control the microstructures of nanoparticles,such as morphology,internal structure and surface structure,which can provide help for further improving the efficiency and low-toxic utilization of pesticide nanoparticles.
