The Preparation of Highly Transparent Layered Double Hydroxides(LDHs)-Poly(Methyl Methacrylate)(PMMA)Nanocomposites Sheets by Batch Cell Polymerization Method

摘要

Enhancement polymer properties using various clay nanocomposites has been interesting in polymer technology.Herein,a preparation of transparent layered double hydroxides/poly methylmethacrylate(LDHs/PMMA)nanocomposites sheet was achieved by batch cell polymerization.Nanometre-sized MgAl-LDHs in toluene showed well dispersed suspension and was translucent,indicating delamination of LDHs stacks.To prepare PMMA-LDHs nanocomposites,the delaminated MgAl-LDHs in toluene was mixed with methymethacrylate oligomer in order to form slurry of dispersed LDHs in PMMA pre-polymer.The LDHs/PMMA nanocomposites sheet was subsequently prepared using batch cell polymerization at 60oC for 5 hours in water bath and it was then post curing at 80oC for 30 minutes.The optical properties of MgAl-LDHs/PMMA nanocomposites were strongly depending upon a dispersion behaviour of MgAl-LDHs.
