Liquid Crystalline of Alumina

In this work commercial ceramic material aluminum oxide (alumina, Al2O3) was grafted and extended by three different monomers using free radical polymerization. These monomers are acrylic acid, 4-(4'-butoxy- and 4'-octoxybenzylideneamino) phenylmthacrylate to produce three polymers; polymer A, polymer B and polymer C. The last two polymers showed liquid crystalline properties. The ability of these three alumina-grafted polymers was examined for adsorption of phenol and p-chlorophenol under different conditions i.e., initial concentrations, pH and temperatures.
