The water-soluble cationic polymer W contains POSS as a core and two layers shell - an inner layer shell consists of the conjugated organic chain and a long chain of hydrophilic polymer as outer layer shell for solubilization in water. The 3D structure renders non-aggregation properties of W in solution as the wavelength for the absorption and luminescence spectra remains unchanged over different concentrations. The effects of ionic strength and pH on the properties of cationic polymer W were studied using UV, dynamic- and static-light scattering (DLS and SLS). © Springer-Verlag 2012.||Source Title:||Polymer Bulletin||URI:||http://scholarbank.nus.edu.sg/handle/10635/65007||ISSN:||01700839||DOI:||10.1007/s00289-012-0709-y|
