Pickering乳液的制备及其在农业中的应用研究进展OA

Pickering emulsions represent a novel emulsion system utilizing solid particles(such as nanoclay,silica,cellu-lose nanocrystals,etc.)as stabilizers.Due to their high stability,low toxicity,and environmental friendliness,they demon-strate broad application prospects in the agricultural sector.This paper reviews the characteristics of Pickering emulsions,their stabilization mechanisms,factors influencing emulsion stability,and the selection of solid particles.It focuses on the progress of Pickering emulsion applications in agriculture:as pesticide carriers for controlled-release and targeted delivery of active ingredients,enhancing utilization rates while reducing environmental pollution;for encapsulating microbial fertiliz-ers or plant hormones to improve their field survival rates and efficacy;as soil conditioners to enhance water retention and nutrient release properties;and as agricultural films and coatings with excellent spreadability,retention,and rain-wash re-sistance.Furthermore,this paper analyzes current challenges facing Pickering emulsions,such as large-scale production costs and unclear mechanisms of particle environmental behavior.It also outlines future research directions,including de-veloping low-cost bio-based particles for agricultural applications and smart responsive Pickering emulsion systems.This review provides a reference for further research and development of Pickering emulsions in agriculture.
