Maya blue is formed from insertion of indigo into palygorskite and sepiolite. Sepiolite and palygorskite are porous fibrous clays. Controlling the insertion, location and organisation of organic molecules in the cavities of nanotubes associated with the release or stability of these molecules is a crucial challenge in the evolution towards...

Unusual self-organization of sepiolite fibbers have been found during the synthesis of sustainable nanocomposites. These auto-structured networks are synthesized starting with an epoxidized linseed oil (ELO), a bio-based hardener of dicarboxylic class and sepiolite fibbers. For the first time, the auto-organization of sepiolite fibbers into...

Le renforcement des polymères est très souvent réalisé par des nanocharges en raison de leursgrandes surfaces de contact, jouant un rôle particulier sur leurs comportements. Parfois de formesanalogues à celles de fibres, ces charges jouent un rôle important dans les propriétés thermiques,mécaniques, optiques ou barrières et permettent de...
