The purpose of this study was to determine the applicability of methyl methacrylate (MMA) and MMA–styrene in treating batai ( Paraserianthes falcataria ) wood. The effectiveness of the treatment was evaluated based on Fourier transform infrared spectroscopy (FTIR) analysis, physico-mechanical properties of the treated wood, and moisture sorption isotherm using dynamic vapour sorption (DVS) apparatus. Physico-mechanical properties of the modified batai wood were improved. The MMA-treated batai wood showed better improvement in terms of physical and mechanical properties compared to the MMA–styrene-treated batai wood. The equilibrium moisture content (EMC) for untreated batai wood was higher than that of treated samples. At 95% RH, the EMC for untreated batai wood was 20.7%, whereas the EMC for MMA- and MMA–styrene-treated samples was 7.9 and 8.8%, respectively. The findings indicate that the modified batai wood absorbed less moisture compared to the untreated batai wood. Moreover, the untreated batai wood had larger hysteresis loop than the treated batai wood. The highest hysteresis value was observed at 80% RH for untreated batai wood (3.8%), followed by MMA–styrene-treated batai wood (1.7%) and MMA-treated batai wood (1.2%). Both MMA and MMA–styrene proved to be effective treatments for batai wood because they reduced its hygroscopicity.

甲基丙烯酸甲酯（MMA）和MMA-苯乙烯改性的八聚木（Paraserianthes falcataria）木材的水蒸气吸附行为和物理力学性能

这项研究的目的是确定甲基丙烯酸甲酯（MMA）和MMA-苯乙烯在处理batai（Parserianthes falcataria）木材中的适用性。基于傅立叶变换红外光谱（FTIR）分析，处理过的木材的物理机械性能以及使用动态蒸气吸附（DVS）装置的水分吸附等温线，评估了处理的有效性。改性八泰木的物理力学性能得到改善。与MMA-苯乙烯处理的batai木材相比，MMA处理的batai木材在物理和机械性能方面表现出更好的改善。未经处理的芭太木木材的平衡水分含量（EMC）高于经处理的样品。在相对湿度为95％的情况下，未经处理的芭提木的EMC值为20.7％，而MMA和MMA苯乙烯处理的样品的EMC值为7.9和8.8％，分别。研究结果表明，与未经处理的芭堤木相比，改性芭堤木吸收的水分更少。此外，未处理的芭提木料比处理的芭提木料具有更大的磁滞回线。对于未经处理的芭tai木（3.8％），在80％RH下观察到最高的磁滞值，其次是由MMA-苯乙烯处理的芭wood木（1.7％）和由MMA处理的芭（木（1.2％）。事实证明，MMA和MMA-苯乙烯都可以有效处理八合木，因为它们降低了其吸湿性。7％）和MMA处理的芭泰木（1.2％）。事实证明，MMA和MMA-苯乙烯都可以有效处理八合木，因为它们降低了其吸湿性。7％）和MMA处理的芭泰木（1.2％）。事实证明，MMA和MMA-苯乙烯都可以有效处理八合木，因为它们降低了其吸湿性。
