| Abstract | |
|
Layered double hydroxides (LDH) suitable for the formulation of polymer composites are designed and characterized. Polymer nanocomposites based on intercalated and exfoliated layered inorganic particles have increasingly attracted research activities due to improved properties of the resulting polymer materials like stiffening, diffusion barrier and thermal stability. The vast majority of such nanocomposites is based on smectite clays like Montmorillonite, an aluminosilicate bearing an anionic layer charge. One of the main challenges for an effective dispersion of those particles in the polymer matrix still remains the design of an appropriate interphase between polymer and particle. We show that inversely charged layered particles are accessible in the form of synthetic layered double hydroxides whose crystallinity and layer charge density can be varied over a broad range by the selection and the ratio of the cations and that their lateral dimensions as well as their surface chemistry are tunable via the synthesis parameters and the anions chosen. We believe our results will point out a feasible route towards a toolbox of a new class of inorganic layered particles for the manufacturing of polymer nanocomposites. |
