The impact of water released from boehmite nanoparticles during curing in epoxy‐based nanocomposites

Abstract The enhancing effect on mechanical properties of boehmite (γ‐AlOOH) nanoparticles (BNP) in epoxy‐based nanocomposites the macroscopic scale encouraged recent research to investigate micro‐ and nanoscopic properties. Several studies presented different aspects relatable an alteration epoxy polymer network formation by BNP with need for further experiments identify mode action. With FTIR‐spectroscopic methods this study identifies interactions matrix during curing process as well cured nanocomposite. data reveals that not themselves, but water released from them strongly influences hydrolysis anhydride hardener or protonation amine accelerator. changes processes are discussed detail. enable new explanation changed material like a lowered glass transition temperature region ( T g ) interphase formation.
