Electropolymerization of coniferyl alcohol

open access: yesJournal of Wood Science, 2009
Electropolymerization of coniferyl alcohol was carried out in an aqueous system (0.2 M NaOH) and in an organic solvent system [CH2Cl2/methanol (4:1 v/v) in the presence of 0.2 M LiClO4] to produce a dehydrogenation polymer (DHP) - artificial lignin. In both systems, the polymerization of coniferyl alcohol was visually confi rmed. In the aqueous system,

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

open access: yesAdvanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...
