Wood–polymer composites (WPC) are commonly prepared by the impregnation and polymerization of active monomers in wood matrix. Due to the inferior interfacial compatibility between wood matrix and hydrophobic polymer interface, the treatment method could not significantly improve the dimensional stability of wood and make full use of the properties of polymer. In this study, a two-step approach was proposed to overcome this problem. The interface bonding between hydrophobic polymer and wood matrix was significantly improved by the formation of covalent bonds. The anti-swelling efficiency (65%), modulus of rupture (120.1 MPa), modulus of elasticity (10.9 GPa) and compressive strength (103.6 MPa) of the wood–polystyrene composites were superior to the wood treated with styrene alone.

木材-聚合物复合材料 (WPC) 通常通过活性单体在木材基质中的浸渍和聚合来制备。由于木材基体与疏水性聚合物界面的界面相容性较差，该处理方法不能显着提高木材的尺寸稳定性和充分利用聚合物的性能。在这项研究中，提出了一种两步法来解决这个问题。通过形成共价键，疏水性聚合物与木材基质之间的界面键合得到显着改善。木材-聚苯乙烯复合材料的抗膨胀效率（65%）、断裂模量（120.1 MPa）、弹性模量（10.9 GPa）和抗压强度（103.6 MPa）均优于单独用苯乙烯处理的木材。
