Synthesis and Characterization of Monodispersed Microgel

Choudhary, Ritu (2011) Synthesis and Characterization of Monodispersed Microgel. MSc thesis.



Monodispersed Poly [N-isopropylacrylamide] (PNIPAM) micro gel has been synthesised by free radical polymerisation reaction. NIPAM, MBA, SDS and KPS were used in proportionate amount for synthesis of PNIPAM microgel. The morphology, shape and size of the prepared monodispersed PNIPAM microgel are characterized by UV-Spectroscopy (UV), Scanning Electron Microscopy (SEM) and Dynamic Light Scattering (DLS) Experimental techniques. The SEM images reveal the particles to be spherical in nature with size of ~ 90 ± 5 nm. The DLS experiments gives the particles size to be ~ 100 ± 5 nm with a polydispersity parameter of 0.157.
