Controlling the thickness of hollow polymeric microspheres prepared by electrohydrodynamic atomization.
In this study, the ability to control the shell thickness of hollow polymeric microspheres prepared using electrohydrodynamic processing at ambient temperature was investigated. Polymethylsilsesquioxane (PMSQ) was used as a model material for the microsphere shell encapsulating a core of liquid perfluorohexane (PFH). The microspheres were characterized by Fourier transform infrared spectroscopy...
متن کاملElectrohydrodynamic Atomization Assisted Encapsulation of Bioactive Compounds
Electrospraying also known as an electrohydrodynamic atomization is a technique for atomizing liquids. The origin of electrospraying is on the base of the charged droplets theory which the interface of the droplets could be deformed by the applied electric field on a liquid droplet which egressing a capillary [1]. Electrospray is a well-known phenomenon which has different applications such as ...
متن کاملControlling the wall thickness and composition of hollow precipitation tubes.
We investigate the growth of self-organized tubes formed by injection of metal salt solutions into silicate solution. The wall thickness increases strictly in an inward direction and obeys square root functions suggesting the presence of a traveling reaction-diffusion front in the radial direction. We also demonstrate the construction of multi-layered tubes.

متن کاملCarboxyl-Functionalized Polymeric Microspheres Prepared by One-Stage Photoinitiated RAFT Dispersion Polymerization
Herein, we report a photoinitiated reversible addition-fragmentation chain transfer (RAFT) dispersion copolymerization of methyl methacrylate (MMA) and methyl methacrylic (MAA) for the preparation of highly monodisperse carboxyl-functionalized polymeric microspheres. High rates of polymerization were observed, with more than 90% particle yields being achieved within 3 h of UV irradiation. Effec...
