“…The absorption bands at 3406, and 1618 cm −1 corresponded to the bands of the O–H bond, and the carbonyl group bending vibration, respectively. Most of the peaks represent major cell wall components in the NLC such as cellulose (1166, 891 cm −1 ), hemicelluloses (1738, 1116, 1051 cm −1 ) and lignin (1597, 1501, 1238 cm −1 ) 30,31 . The absorption peak of the NLC/CaCO 3 /PMMA composites at 1466 cm −1 was due to the ν 3–3 CO 3 2− and ν 3–4 CO 3 2− 32 .…”

The purpose of this study was to develop a rapid and green method for the synthesis of lignocelluloses-based materials with superior mechanical properties. Samples were produced by hot-pressed method using different concentrations of CaCO3 and poly (methyl methacrylate) particles-filled nanolignocelluloses composites which was synthesized through mechano-chemical method. Poly (methyl methacrylate) and CaCO3 nanoparticles have been used as nanofillers. Bending strength, elasticity modulus, and dimensional stability, thermal properties of the developed lignocelluloses-based composites were determined. In view of the experimental results, it is found that the composites materials have good mechanical, dimensional stability, and thermal properties which enhanced as the filler loading increased. Thus, herein described lignocelluloses-based materials showed important characteristics to be concluded that these composites are suitable to be used for the design of flooring and construction systems.

“…Similar studies also confirmed that the CoFe 2 O 4 nanoparticles with lager magnetocrystalline anisotropy and reasonable magnetization could be easily grown on the wood template by a hydrothermal process [17][18][19]. However, the greatest hurdle to the broader use of wood/magnetic composites was the absence of the structure-property relationships.…”

“…As our easily report, the untreated wood shows non-magnetic characterizes. But the magnetic wood exhibits a polar property and shows a typical ferromagnetic behavior[18,19]. The saturation magnetization (M S ) of the samples synthesized at 50 o C, 70 o C, 90 o C, 110 o C and 130 o C were 0.11 emu/g, 0.67 emu/g,…”

“…Natural bamboo samples went through four stages of degradation (Figure D,E). The first stage started at about 100°C, which was attributed to the loss of free water from bamboo cells, while the next stage occurred in the range of 220°C to 420°C due to the thermal degradation of hemicellulose, lignin and cellulose . For LB, the degradation behaviors could only be divided into two stages, which refer to the stage of water evaporation, lignin retention and cellulose degradation .…”

Shaped-stabilized reversible thermochromic phase change materials of (TBC-LB, TBB-LB) were assembled by impregnation the TBC (crystal violet lactone/ bisphenol A/tetradecanol) or TBB (3,3 0 -Bis (1-n-octyl-2-methylindol-3-yl) phthalide/bisphenol A/tetradecanol) into lignin-retained bamboo (LB) for energy storage. Analysis of the chemical structure of lignin-retained wood showed that the removal of part of lignin from the bamboo contributes to the penetration of the compound, and the partial retention of lignin is advantageous for maintaining high mechanical properties. The SEM micrographs of TBC-LB and TBB-LB indicate that TBC and TBB are well immersed into the porous LB. The TBC-LB showed an endothermic peak at 40.8 C with ΔH m of 113.3 J g −1 and two exothermic peaks at 28.8 C and 21.9 C with ΔH L+S of 110.2 J g −1 , and the value is basically equal to the pure TBC compound, indicating that TBC has been fully immersed in LB to form a composite phase change material. For phase change latent heat and melting-cooling temperature, TBB-LB and TBC-LB showed the same trend. About 100 heating-cooling cycles were performed to evaluate the reliability of TBC-LB and TBB-LB, showing excellent cycle stability. It is foreseen that the prepared shape-stable TBC-LB and TBB-LB have great potential for applying insulation systems in reversible thermochromic phase change energy storage.
