摘要：A novel waterborne hyperbranched polyacrylate (HBPA) emulsion containing exfoliated organomontmorillonite (OMMT) was synthesized and used to modify wood. The thus-modified wood was characterized and tested. Comparing with linear polyacrylate (PA), the HBPA had smaller particle size and lower viscosity. Part of MMT layers and HBPA successfully entered into wood cell walls. After heating, the hydrophobic HBPA formed a layer of film, which benefited to the highly improved properties of wood. The content of volatile organic compounds (VOCs) of modified wood was lower than that of the unmodified wood. All the results suggested the modified wood was prospective for structural materials. @ 2021 Elsevier Ltd. All rights reserved.
