液相沉积法(LPD)是湿化学法中发展起来的一种全新成膜方法,现已广泛应用于集成电路、金属-氧化物半导体、生物传感器、光催化及抗菌材料领域功能性薄膜的制备。本文简要介绍了液相沉积法的原理、特点及采用LPD法制备的多种金属氧化物薄膜,并详细综述了近年来液相沉积技术在分析化学领域中的应用,主要包括LPD在制备分离介质、化学传感器、复合电极等材料中的应用,并对LPD法在分析化学中的未来发展趋势进行了展望。
Liquid phase deposition(LPD) technique,developed from wet chemical processing,is a new thin film-forming method to create thin oxide films from aqueous solutions.Due to the distinguishing characteristic of LPD,it has received increasing interest in recent years and been widely used in many fields,especially in the preparation of functional oxide coatings for integrated circuit,metal oxide semiconducting nanomaterials,biosensor,photocatalysis and antibacterial materials.In current review,we first briefly introduced the basic principles and characteristics of LPD and then summarized previous empirical studies for the preparation of metal oxide thin films fabricated by using LPD technique.Furthermore,the applications of LPD method in analytical chemistry,such as the preparation of separation media for chromatography and solid-phase extraction,chemical sensors and composited electrodes,are discussed in detail.At last,the future development and application of LPD in analytical chemistry is prospected.
