PHASE TRANSFORMATIONS IN REGENERATED MICROCRYSTALLINE CELLULOSE FOLLOWING DISSOLUTION BY AN IONIC LIQUID

open access: yesBioResources, 2010
Phase transformations in microcrystalline cellulose (MCC) were studied following dissolution of 5, 10, and 20 wt. % MCC in the ionic liquid 1-butyl-3-methylimidazolium formate (BMIMFmO) and regeneration via water.

Properties of Lignocellulosic Composites Containing Regenerated Cellulose Fibers

open access: yesBioResources, 2014
The aim of the paper was to examine the application of regenerated cellulose fibers as a reinforcement material in particleboard production. Single-layer, 10 mm thick panels, with the density of 800 kg/m3 were produced with addition of regenerated ...

Molecular orientation distribution of regenerated cellulose fibers investigated with rotor synchronized solid state NMR spectroscopy [PDF]

open access: yes, 2019
A regenerated cellulose fiber is, in contrast to cotton, a man-made fiber. In the fiber production, the cellulose polymer is subject to various processing steps, affecting the underlying molecular orientation distribution, which is a determining factor ...

Simple method for obtaining regenerated cellulose nanoparticles from delignified coffee parchment, and their use in fabricating blended films

open access: yes, 2023
: Cofee parchment is one of the residues generated in cofee processing and has been poorly explored for value-added applications. It has been reported that cofee parchment has a high cellulose content (40–49%).

Elucidation of the effect of ionic liquid pretreatment on rice husk via structural analyses

open access: yesBiotechnology for Biofuels, 2012
Background In the present study, three ionic liquids, namely 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), 1-ethyl-3-methylimidazolium acetate ([EMIM]OAc), and 1-ethyl-3-methylimidazolium diethyl phosphate ([EMIM]DEP), were used to partially dissolve ...
