“…and are thermally stable at high temperatures not requiring flame retardants [203]. When metal nanoparticles (Pt) were deposited onto natural fibers (softwood, hemp) and subsequently incorporated into the lignin matrix, composites with reduced electrical resistance were produced [204][205][206][207].…”

“…Lignin, which is mainly used as fuel due to its high calorific value, can also be used as a filler in various polymer compounds. Applications in electronic devices are also targeted: one new development is to implement wood-based polymers as bipolar plates for direct methanol fuel cells as well as other types of electrodes (Haensel et al 2009(Haensel et al , 2010.…”

In this report, X-ray induced photoelectron spectroscopy (XPS) measurements of the valence band structure of cellulose and lignin are combined with a theoretical reconstruction of the spectra based on density functional theory (DFT) calculations. These calculations involve an analysis of the valence band structures and their respective orbitals in which basic units of cellulose and lignin are considered. In addition, photoionization cross sections are incorporated for reconstruction of the XPS spectra. This combination of theoretical calculations and experimental measurements revealed that an emission present up to 10 eV in the valence band structure is dominated by oxygen rather than by carbon, as reported in literature. Furthermore, a quantitative elemental analysis shows significant carbon contributions at binding energies above 13 eV. The valence band analysis supported by DFT provides a powerful basis for a detailed interpretation of spectroscopic data and enables a profound insight into application relevant processes in future.

“…The main uses for this material at present are as carcasses for electronic equipment (televisions, audio and video equipment), food industry components (containers, plates, cups, etc. ), and a line of furniture is currently being designed that has the appearance of wood but which has lower production costs and produces less waste material than wood due to the degradability of coconut fiber [6,7].…”

Antioxidant and antibacterial effects of natural phenolic compounds on green composite materials

et al. 2012

The aim of this study is to establish the thermal characteristics of a biocomposite (Arbofill kokos®), stabilized with different natural phenolic additives, in order to check the antioxidant capacity of the resulting compounds on the biocomposite. The phenolic compounds used were thymol, carvacrol, α-tocopherol and tannic acid, and the concentrations used were 0.5wt% and 2wt% of each compound. The results obtained were compared with the same biocomposite stabilized with an industrial antioxidant agent (octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate). Thermo-analytical techniques were used (DSC and TGA) to carry out the study. The antimicrobial effect of these natural phenolic compounds on the biocomposite was also studied by analyzing of the growth of bacterial colonies. The comparison between the phenolic compounds and the industrial compound showed good antioxidant action of the phenolic compounds on the base biocomposite; in all the mixtures of biocomposite and antioxidant agent the oxidation onset temperature (OOT) of the biocomposite increased. Of all the phenolic compounds studied the highest OOT was achieved with α-tocopherol, which, compared with the temperature of the base composite, showed an increase of almost 45%.
