Layered Double Hydroxides as Nano Additives in Poly(-caprolactone)
Poly(-caprolactone) nanocomposites were prepared by melt compounding with organo-modified layered double hydroxides (LDH). The LDH were intercalated with stearic acid (LDH-stearate) or with sodium dodecyl sulphate (LDH-SDS). Nanocomposites morphology was studied by XRD and TEM. Thermal
properties were analysed by TG and DSC. Although both systems showed presence of a mixed morphology, exfoliated and intercalated, LDH-stearate nanocomposites showed a better dispersion of inorganic platelets. TEM images showed the presence of individual platelets in the PCL matrix. LDH-SDS
