Sonicated Urea-Formaldehyde Microcapsules
Media Details
Created 7/13/2004
ESEM images of sonicated urea-formaldehyde (UF) microcapsules. UF capsules were centrifuged from the aqueous solution in which they were formed and then air dried on a glass slide. Sonication was used to decrease the size of capsules and create smooth surfaces. All of the microcapsules are clumped together and range in diameter between hundreds of nano meters and a few microns. Separation of these clumped micro-capsules is currently being investigated for uses in self-healing polymers. For more information, please visit http://www.autonomic.uiuc.edu/
