Composition‐Tunable Lignocellulosic Aerogels From Eucalyptus spp. Bark for Oil and Cu2+ Adsorption

open access: yesJournal of Applied Polymer Science, EarlyView.
Composition‐tunable lignocellulosic aerogels are produced from Eucalyptus spp. bark by combining cellulose, lignin, and microfibrillated cellulose without post‐synthetic functionalization. The resulting porous architectures show contaminant‐dependent performance: CEL favors cooking‐oil uptake, CEL‐M favors pump‐oil uptake, and CEL‐L‐M provides the ...
