Hydroxypropyl cellulose (HPC) has a relatively low viscosity, allowing for microchip channel filling to be performed with ease at concentrations as high as 5%, a MES/TRIS buffer system at pH 6.1 eliminates the need for surface preconditioning procedures due to the promotion of hydrogen bonding of HPC with the wall. Hydroxypropyl cellulose (HPC) is used as a core molecule for controlled grafting of monomers by ATRP. Hydroxypropyl cellulose (HPC) is either allowed to react with an ATRP initiator or the first generation initiator-functionalized 2,2-bis(methylol)propionic acid dendron to create macroinitiators having high degrees of functionality. Hydroxypropyl cellulose (HPC)/vinyl polymer networks are synthesized in film form from liquid-crystalline solutions of HPC in a mixed solvent of methacrylate monomer/methanol/water (2:1:2 in weight) containing cross-linking agents, via photopolymerization of the methacrylate monomer. The polymer composite films, HPC/PDEGMEM and HPC/PHPMA, prepared at ca. 60-70 wt % concentrations of HPC in the starting solutions, are iridescently colored due to the selective light reflection, originating from the cholesteric helical arrangement carried over successively into the network system.
