Fig. 6From: The effect of delignification ratio on the PMMA occupation in poplar wood cell wall by the macro and micro comparative studyMesopore-size distribution and accumulated volume of DW (a) and PMMA/DW (b). The horizontal axis range of control and DW-17.4,29.9,51.7,73.2,97.3 are 0–18. The horizontal axis range of PMMA / DW-0,17.4,29.9,51.7,73.2 are 0–24, and the horizontal axis range of PMMA / DW-97.3 is 60–200Back to article page
