Model films of cellulose II - Improved preparation method and characterization of the cellulose film

open access: yes, 2004
An optimization study of the preparation of spin-coated cellulose model films from the NMMO/DMSO system on silicon wafers has been made. The study shows that the cellulose concentration in the solution determines the cellulose film thickness and that the

Anion specific adsorption of carboxymethyl cellulose on cellulose

open access: yesLangmuir, 2023
Integration of fiber modification step with modern pulp mill is a resource efficient way to produce functional fibers. Motivated by the need to integrate polymer adsorption with the current pulping system, anion-specific effects in Carboxymethylcellulose (CMC) adsorption have been studied.

Exploration on ability of printable modified papers for the application in heat sublimation transfer printing of polyester fabric

open access: yesScientific Reports, 2023
In this work heat transfer papers were loaded with a new core–shell pigment based on precipitating thin shell of titanium dioxide on a core of rice husk silica ash TiO2/RHSA to be applied in dye sublimation printing of textile fabrics. Besides, 0.1% (w/w)

Studies on the Cellulose-Binding Domains Adsorption to Cellulose [PDF]

open access: yesLangmuir, 2004
Cellulose-binding domains (CBD) are modular peptides, present in many glycanases, which anchor these enzymes to the substrate. In this work, the effect of CBD adsorption on the surface properties of a model cellulose, Whatman CF11, was studied. The methods applied include inverse gas chromatography (IGC), ESCA, X-ray diffraction, and scanning electron ...
