*2.3. Resin Soaking after Plasma Treatment*

After treatment with cold plasma, the bamboo specimens, including culms and strips, were soaked with the 2D resin for 24 h. Subsequently, they were placed in a drying oven initially set at 60 ◦C, and the temperature was increased to 100 ◦C at a rate of 10 ◦C/min. Finally, the samples were taken out after the temperature subsided gradually to 40 ◦C.
