Front Cover: In article number 2000197 by Mustapha Raihane, Mehmet Atilla Tasdelen, and co-workers, thermoset nanocomposites containing methacrylated halloysite nanotubes are prepared by in situ free radical photocrosslinking polymerization using multifunctional methacrylates. The chemical attachment of halloysite nanotubes not only improve tensile strength and elasticity modulus of the obtained nanocomposites, but also enhance their thermal properties.
