Realizing eco-friendly, long-term, and low-risk aphid control on Lycium barbarum (medicinal cash crop) using a Cynanchum komarovii extracts eucalyptus oil-loaded microcapsules (EOMCs) formulation compositions is viable. In this study, the aim to optimize composition of EOMCs for effective aphids, release was controlled by changing cross-linking degree shell match characteristics extracts. Four types polyamines were used as agents preparation interfacial polymerization. The bioactivity, wettability, field application efficacy different evaluated. These exhibited an encapsulation efficiency exceeding 85 %. with moderate rate aphids remained at 62.86 %, while combination fastest slowest rates only 48.62 % 57.11 respectively. all four found be safe Chinese wolfberry plants. Overall, selecting appropriate during fabrication, can effectively achieve sustainable in through compounding selected microcapsules.

Polymer Capsules with Volatile Organic Compounds as Reference Materials for Controlled Emission

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер unknown

Опубликована: Дек. 4, 2024

Encapsulation of volatile organic compounds (VOCs) that could evaporate at a defined rate is immense interest for application in emission reference materials (ERMs). Polyurethane/polyurea microcapsules with various VOC active ingredients (limonene, pinene, and toluene) were successfully produced by interfacial polymerization Shirasu porous glass membrane emulsification size range between 10 50 μm. The effect surfactant, VOC, monomer(s) type, ratio has great on the formulation process morphology capsules. type played significant role encapsulation efficiency. Due to difference vapor pressure VOC/water tension, was optimized each individual VOC. Furthermore, achieve effective stability large droplets/capsules, combination ionic nonionic surfactants used. Optical scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), used characterize microcapsules. results showed obtained exhibited spherical shape core–shell featured characteristic urethane-urea bonds. amount encapsulated ranges 54 7 wt %. tests performed help test chamber procedure (EN 16516). limonene-loaded polyurethane/polyurea show change less than 10% within 14 days can be considered as potential candidate use an ERM.
