A Review on Natural Fiber Bio-Composites, Surface Modifications and Applications

Abstract

Increased environmental concerns and global warming have diverted focus from eco-friendly bio-composites. Naturals fibers are abundant and have low harvesting costs with adequate mechanical properties. Hazards of synthetic fibers, recycling issues, and toxic byproducts are the main driving factors in the research and development of bio-composites. Bio-composites are degradable, renewable, non-abrasive, and non-toxic, with comparable properties to those of synthetic fiber composites and used in many applications in various fields. A detailed analysis is carried out in this review paper to discuss developments in bio-composites. The review covers structure, morphology, and modifications of fiber, mechanical properties, degradable matrix materials, applications, and limitations of bio-composites. Some of the key sectors employing bio-composites are the construction, automobile, and packaging industries. Furthermore, bio-composites are used in the field of medicine and cosmetics.

Use of Chènevotte, a Valuable Co-Product of Industrial Hemp Fiber, as Adsorbent for Pollutant Removal. Part I: Chemical, Microscopic, Spectroscopic and Thermogravimetric Characterization of Raw and Modified Samples

“…The analysis of the DTG curve of SHI-R showed a two-stage thermal decomposition process. A first mass loss in the range of 260 to 380 °C with a maximum slope at 318.1 °C can be associated with the simultaneous degradation of hemicelluloses, cellulose and lignin [ 70 ]. It follows a second mass loss, partially convoluted with the first one, evidenced by a different slope in the range of 380 to 600 °C, which is likely associated initially with the end of the cellulose decomposition and then with the main process of thermal decomposition of the lignin polymer structure.…”

Advances in 3D Printing for Tissue Engineering

“…The usefulness of biodegradable synthetic polymers (mainly aliphatic polyesters such as PCL or PLGA) in TE has already been investigated for many years [103,104]. The biodegradable aliphatic polyesters are characterized by relatively low toxicity [105]; however, the acidic oligomeric release, being the effect of polymer hydrolytic degradation, can initiate the inflammatory reaction [106], negatively affecting the tissue regeneration process [107].…”

High-power Terahertz Waves for a Recycle System of Amyloid Fibrils

“…In contrast, those fibrous conformations were reversely selfassociated by the irradiation of 0.42 THz wave tuned to 720 m from gyrotron, as shown by optical and IR microscopies, SEM, and small-angle X-ray scattering. The overall reaction is performed at room temperature within 30 min without external heating and high-pressures.Therefore, amyloid fibrils can be dissociated and associated under the proper far-infrared radiation conditions, which inspires a sustainable recycling system of fibrous biomaterials.In recent years, fiber-type biomaterials have attractive attentions in various industrial fields [1][2][3][4][5][6][7][8][9][10][11][12][13][14] .As a representative biomaterial, cellulose nanofiber can be developed for cosmetic additives 1 , anti-bacterial sheets, and porous materials in healthcare and pharmaceuticals fields 2,3 , and for components of electronic devises and auto parts in mechanical industries 4,5 . As with the cellulose, amyloid fibrils can also be utilized as functional biomaterials.…”
