Preparation and performance testing of smart hydrogel water and fertilizer retainers responsive to pH changes
响应pH变化的智能水凝胶保水肥制备与性能测试

摘要

本文研究了一种响应pH变化的智能水凝胶，旨在提高水凝胶的保水性能和肥料释放效率。采用多功能水凝胶材料，通过调整其化学结构，使其在不同pH值环境下展现出优异的响应性。这种水凝胶不仅具备较强的水分吸收能力，还能有效控制肥料的缓释，从而改善土壤肥力，提升作物生长的效果。实验结果表明，所制备的智能水凝胶具有较好的pH响应性和较长时间的肥料释放能力，在农业灌溉中具有广泛的应用潜力。本研究为智能水凝胶的开发提供了新的思路，并为其在农业领域中的应用奠定了基础。

Abstract

This paper studies a type of smart hydrogel responsive to pH changes, aiming to improve the water retention performance and fertilizer release efficiency of hydrogels. Multifunctional hydrogel materials are used, and by adjusting their chemical structure, they exhibit excellent responsiveness in environments with different pH values. This hydrogel not only has strong water absorption capacity but also can effectively control the slow release of fertilizers, thereby improving soil fertility and enhancing the effect of crop growth. Experimental results show that the prepared smart hydrogel has good pH responsiveness and long-term fertilizer release capacity, and has broad application potential in agricultural irrigation. This research provides new ideas for the development of smart hydrogels and lays a foundation for their application in the agricultural field.
