SENSING THE ELECTROKINETIC POTENTIAL OF CELLULOSIC FIBER SURFACES
Electrical charges on surfaces can play a dominant role in the interactions of lignocellulosic materials (Davison and Cates 1975; Lindström 1996). This review focuses on sensing and quantifying effects of such charges by means of electrokinetic tests.

The role of electrostatic interactions of anionic and cationic ...
Some of the most popular cellulose derivatives exhibit charged functional groups, either cationic (generally, quaternary ammonium moieties) or anionic (most typically, carboxylate groups).

The surface charge of regenerated cellulose fibres - Springer
In this paper the influence of charged species on the sheet strength of viscose fibres was investigated. Four samples of chemical modified viscose fibres, as well as a reference fibre were studied. The swelling of these viscose fibres and the breaking length of hand sheets have been determined.

Evaluation of cellular attachment and proliferation on different ...
Fabrication and characterization of different surface charged cellulose electrospun scaffolds including cellulose acetate (CA), cellulose, carboxymethyl cellulose (CMC) and quaternary ammonium cationic cellulose (QACC) for biomedical applications have been reported in this research.

Enhancing the inter-fiber bonding properties of cellulosic fibers by ...
Cellulosic fiber has been increasingly used in many fields. The fiber charge, including the surface charge and inner charge, affects the properties of cellulosic fiber and fiber-based materials significantly.

Antistatic, Flame‐Retardant, and Mechanically Resistant Cellulose ...
To address these issues, this work proposes a sustainable alternative using microfibrillated cellulose (MFC) and carbon black (CB) to create conductive cryogels by the freeze-drying method.

Cellulose fiber - Wikipedia
Hydrophilicity, roughness and surface charge determine the interaction of cellulose fibers with an aqueous environment.

On the determination of charge and nitrogen content in cellulose fibres ...
The multifunctionality of the substituent group, i.e. being nitrogen con- taining, carrying a cationic charge and having an electrostatically bound counterion, provides several approaches for evaluation of the specific DS.

The Significance of Surface Charge and Structure on the Accessibility ...
The pre-treatment of cellulose fibres improves the accessibility of dissociable groups. Further improvement of hydrophilicity (mercerisation) causes a pronounced increase in the surface charge density and a reduction in the degree of crystallinity and structural modifications.

Customising Sustainable Bio-Based Polyelectrolytes: Introduction of ...
This comprehensive study proves that highly charged, cellulose-based cationic and hydrophobic polyelectrolytes can be tailored through an adequate set of modifications: periodate oxidation, cationization, and hydrophobisation.
