Abstract

Polysilsesquioxane (PSQ) hollow spheres show great potential in various fields, including catalysts, environmental protection, and drug delivery, owing to their high stability, large interior cavity, and adjustable surface chemistry. However, the fabrication of amino-functionalized PSQ hollow spheres (AHPSQ) with inherent amine groups on the surface still remains a challenge partly due to the hydrophilicity of the silane precursor. In this study, for the first time AHPSQ was fabricated via a facile sol-gel process utilizing aminopropyltrimethoxysilane and methyltrimethoxysilane as co-precursor in an ice bath. The pH-sensitive release behavior of AHPSQ was demonstrated using avermectin as a pesticide model and the release kinetics were analyzed. The artificial ultraviolet accelerated experiment confirmed that the carrier has an ultraviolet protective effect on the pesticide and can reduce the ultraviolet degradation rate.

胺功能化聚硅氧烷中空纳米微球用于ph响应型紫外屏蔽农药释放系统

聚倍半硅氧烷（PSQ）空心球由于其高稳定性、大内腔和可调节的表面化学性质，在催化剂、环境保护和药物递送等领域显示出巨大的潜力。然而，部分由于硅烷前体的亲水性，表面具有固有胺基的氨基官能化PSQ空心球（AHPSQ）的制备仍然是一个挑战。在本研究中，首次在冰浴中利用氨基丙基三甲氧基硅烷和甲基三甲氧基硅作为共前驱体，通过简单的溶胶-凝胶工艺制备了AHPSQ。以阿维菌素为农药模型，研究了AHPSQ的pH敏感性释放行为，并对其释放动力学进行了分析。人工紫外线加速实验证实，该载体对农药具有紫外线防护作用，可降低紫外线降解率。
