Title: Dual role of alkoxyamine-functionalized lamellar materials in the synthesis of hybrid polymers.

Abstract: [Display omitted] • Impact of Sol-gel synthesis conditions on lamellar structure. • Impact of solvent type on lamella delamination efficiency. • Alkoxyamine-functionalized lamellar materials as fillers and radical polymerization initiators. • In situ preparation of nanocomposites composed of lamellar polysilsesquioxane and polystyrene. Alkoxyamine-functionalized polysilsesquioxane lamellar materials were used as fillers and radical polymerization initiator in the synthesis of nanocomposites. This work is divided into three parts: (i) the synthesis and the characterization of functionnalized-lamellae, (ii) the study of their delamination and (iii) the polymerization leading to the nanocomposites. The presence of covalently bonded siloxane filler reinforced the polystyrene. In addition, the EPR analysis showed that alkoxyamine groups were still present on the nanocomposite and could be homolyzed under thermal condition to enable further potential functionalisations.
