A Natural Lignification Inspired Super‐Hard Wood‐Based Composites with Extreme Resilience

open access: yesAdvanced Materials, EarlyView.
Super‐hard wood‐based composites (WBC) are designed and developed inspired by the mesoscale homogeneous lignification process intrinsic to tree growth. This innovative hybrid structure is achieved by leveraging the infusion of low‐molecular‐weight phenol formaldehyde resin into the cell walls of thin wood slices, followed by a unique multi‐layer ...
