Journal ArticleDOI
Nanofiber composites of polyvinyl alcohol and cellulose nanocrystals: manufacture and characterization.
TL;DR: The elastic modulus of the nanocomposite mats increased significantly as a consequence of the reinforcing effect of CNs via the percolation network held by hydrogen bonds, but this organization-driven crystallization was limited as observed by the reduction in the degree of crystallinity of the CN-loaded composite fibers.
Journal ArticleDOI
A comparative study of energy consumption and physical properties of microfibrillated cellulose produced by different processing methods
Kelley L. Spence,Richard A. Venditti,Orlando J. Rojas,Orlando J. Rojas,Youssef Habibi,Joel J. Pawlak +5 more
TL;DR: In this paper, the effect of processing on microfibril and film properties, relative to energy consumption, was investigated for bleached and unbleached hardwood pulp samples.
Journal ArticleDOI
The effect of chemical composition on microfibrillar cellulose films from wood pulps: water interactions and physical properties for packaging applications
Kelley L. Spence,Richard A. Venditti,Orlando J. Rojas,Orlando J. Rojas,Youssef Habibi,Joel J. Pawlak +5 more
TL;DR: In this paper, microfibrillated celluloses (MFCs) and associated films generated from wood pulps of different yields (containing extractives, lignin, and hemicelluloses) have been investigated.
Journal ArticleDOI
The effect of chemical composition on microfibrillar cellulose films from wood pulps: Mechanical processing and physical properties
Kelley L. Spence,Richard A. Venditti,Youssef Habibi,Orlando J. Rojas,Orlando J. Rojas,Joel J. Pawlak +5 more
TL;DR: Interestingly, after homogenization, the presence of lignin significantly increased film toughness, tensile index, and elastic modulus, indicating that MFC films can potentially be made from low-cost recycled cellulosic materials.
Journal ArticleDOI
Cellulose-Lignin Biodegradable and Flexible UV Protection Film
Hasan Sadeghifar,Hasan Sadeghifar,Richard A. Venditti,Jesse S. Jur,Russell E. Gorga,Joel J. Pawlak +5 more
TL;DR: In this article, Azide modified cellulose dissolved in dimethylacetamide/lithium chloride (DMAc/LiCl) was reacted with propargylated lignin to produce 0.5, 1, and 2% by weight cellulose-lignin containing materials.
