Organic layered double hydroxide (LDH) modified with UV curing acrylate group was synthesized by two steps method

which was first intercalated with sodium dodecyl sulfate (SDS) and then grafted by semiadduct of isophorone diisocyanate and 2-hydroxyethyl acrylate (IPDI-HEA).The reactive groups of the LDH would join in the UV curing reaction when exposed to the UV lamp

obtaining the exfoliated polymer/LDH nanocomposites via in situ polymerization.The X-ray diffraction (XRD) and Fourier transform infrared (FTIR) analyses were used to confirm the formation of modified LDH.Transmission electron microscope (TEM) observation of UV-cured nanocomposites indicated the exfoliated microstructure of LDH in the matrix of polymer.The thermal stability and mechanical properties were also measured.The results showed that the onset decomposition temperature of nanocomposite with 5% LDH loading increased by 64.6 K compared to the pure polymer

while the residual char increased to 8.7% from 4.0%.Also the tensile strength were enhanced to 14.7 MPa compared with 8.5 MPa of the pure polymer.As a result

the combination properties of UV-cured polymer/LDH showed great enhancements in comparison with polymer without LDH addition.
