Cunha A, Lundahl M, Ansari M, Johansson L, Campbell J, Rojas O
ACS Appl Nano Mater
. 2018 Oct;
1(9):5279-5288.
PMID: 30320301
Colloidal dispersions of cellulose nanofibrils (CNFs) are viable alternatives to cellulose II dissolutions used for filament spinning. The porosity and water vapor affinity of CNF filaments make them suitable for...

30(31):9327-35.
PMID: 25046221
Nanocelluloses are bio-based nanoparticles of interest as stabilizers for oil-in-water (o/w) Pickering emulsions. In this work, the surface chemistry of nanocelluloses of different length, nanofibrillated cellulose (NFC, long) and cellulose...

Biomacromolecules
. 2008 Jan;
9(2):610-4.
PMID: 18220351
Because of conflicting reports and unrealistic literature values, a systematic study of the surface energy of chitin, chitosan, and their respective monomeric counterparts was carried out using contact angle measurements...

Cunha A, Freire C, Silvestre A, Neto C, Gandini A, Orblin E, et al.
J Colloid Interface Sci
. 2007 Sep;
316(2):360-6.
PMID: 17889889
The controlled heterogeneous modification of cellulose fibers with trifluoroacetic anhydride was investigated. The characterization of the ensuing materials was performed by elemental analysis, FTIR spectroscopy, X-ray diffraction (XRD), thermogravimetry, and...

Langmuir
. 2007 Sep;
23(21):10801-6.
PMID: 17854212
The surface modification of cellulose fibers with 3,3,3-trifluoropropanoyl chloride (TFP) was studied in a toluene suspension. The characterization of the modified fibers was performed by elemental analysis, Fourier transform infrared...

. 2007 Mar;
8(4):1347-52.
PMID: 17378606
New highly hydrophobic/lipophobic biopolymers were prepared by the controlled heterogeneous pentafluorobenzoylation of cellulose substrates, i.e., plant and bacterial cellulose fibers. The characterization of the modified fibers was performed by elemental...

. 2006 Jun;
301(1):333-6.
PMID: 16777121
The surface modification of cellulose fibers with trifluoroacetic anhydride (TFAA) was studied using the heterogeneous cellulose/TFAA/pyridine/toluene system. The degree of substitution (DS) of the ensuing trifluoroacetylated fibers ranged from 0.04...
