Design and Preparation of Attractive Pickering Emulsion Gels
Jia Zhang, Dong Chen
Zhejiang University
The preparation of water-in-oil emulsion gel is less studied, which strongly limits their applications. Here, attractive Pickering emulsion gels (APEG) are designed and prepared by emulsifying the water phase into droplets in the continuous oil phase. Shellac nanoparticles are dispersed in water phase and polymers functionalized with α,ω-diamino can dissolve in oil phase. Functionalized polymer with two amino end groups can simultaneously bind to two carboxyl functionalized shellac nanoparticles and forming a bridged network. The APEG systems are water-in-oil, which can be confirm from fluorescent confocal microscope images. The APEG systems show typical shear-thinning behaviors and excellent stability, making them ideal for direct 3D printing, which can be directly printed in air and water. The strategy of preparing APEGs is versatile and different APEG systems can be designed according to requirements. Different hydrophobic actives and hydrophilic actives could simultaneously and effectively be loaded in the oil and water phases, respectively, making APEGs advantageous for drug encapsulate and delivery, making the APEG systems promising for a wide range of applications.
