Astonishingly uniform polypyrrole nanocoating on morphologically complex cellulosic substances was achieved without disrupting the hierarchical network structures of individual cellulose fibers by means of polymerization-induced adsorption.

Liquid crystalline cellulosic-based solutions described by distinctive properties are at the origin of different kinds of multifunctional materials with unique characteristics. These solutions can form chiral nematic phases at rest, with tuneable photonic behavior, and exhibit a complex behavior associated with the onset of a network of director field defects under shear. Techniques, such as Nu...

The use of bio-based materials has become a focus research nowadays. For the development new generations advanced resources, renewable and available resources must be combined with technologies. Researchers have looked into biomass waste cellulosic as sustainable sources for nano-crystalline cellulose extraction. Besides different treatment methods suitable various applications, this review aim...

The objective of this research was to evaluate an all-chemical process to prepare nano-scale to macro-scale cellulosic fibers from kenaf bast fibers, for polymer composite reinforcement. The procedure used in this all-chemical process included alkaline retting to obtain single cellulosic retted fiber, bleaching treatment to obtain delignified bleached fiber, and acidic hydrolysis to obtain both...

Probing the surface morphology of microthin fibers such as naturally occurring biofibers is essential for understanding their structural properties, biological function, and mechanical performance. The state-of-the-art methods for studying the surfaces of biofibers are atomic force microscopy imaging and scanning electron microscopy, which well characterize surface geometry of the fibers but pr...

The cellulosic fabrics cotton, rayon, and Tencel® are commonly used in the textile industry (Kroschwitz, 1990). The chemical composition of the fabrics is similar, but they differ in the arrangement of the cellulose polymers in the fabrics (Collier and Tortora, 2001). The basic polymer for all cellulosic fibers consists of repeating glucose units. For the cotton fabric, the cellulosic polymers ...

Cellulose, being the major cell wall component and the most abundant organic matter, produced by living organisms, is not uniformly distributed within plant tissues. There are numerous cells, like the parenchyma ones, which even at maturity have thin cell wall. Thick cell walls are characteristic for the tissues with mechanical function. Among those, there are cell walls, which contain several ...
