Controlled interactions between silanol groups at the surface of sepiolite and an acrylate matrix: Consequences on the thermal and mechanical properties

► Coupling of sepiolite silanols with an elastomeric matrix (PHEA). ► Protection of sepiolite silanols against PHEA. ► Interface effect of sepiolite/PHEA on the nanocomposite reinforcement. ► Controlled reinforcement due to sepiolite/PHEA interactions.
