Nanoscale chemical features of the natural fibrous material wood.

We report the use of the PFIR to characterize the chemical modification of biobased native and intact wooden matrices, which has evolved into an increasingly active research field. The distribution of functional groups of wood cellulose aggregates, either in native or carboxylated states, was detected with a remarkable spatial resolution of 16 nm. Furthermore, mechanical and chemical maps of the distinct cell wall layers were obtained on polymerized wooden matrices to localize the exact position of the modified regions. These findings shall support the development and understanding of functionalized wood materials. PMID: 32852940 [PubMed - as supplied by publisher]
