“…The presence of the bamboo fiber significantly elevated the average dielectric loss profile in comparison to the pure cotton bond paper. This disparity in response is attributed to the high lignin content in bamboo [18]. In fact, the lignin content in bamboo (20%–26%) is substantially higher than the normal range of lignin in nonwoody biomass (11%–27%), and closely resembles the ranges reported for softwoods (24%–37%) and hardwoods (17%–30%) [19].…”

Current product composition and quality test methods for the paper and pulp industry are mainly based on manual ex-situ wet-bench chemistry techniques. For example, the standard method for determining the furnish of paper, TAPPI T 401 “Fiber analysis of paper and paperboard,” relies on the experience and visual acuity of a specially trained analyst to determine the individual plant species present and to quantify the amount of each constituent fiber type in a sheet of paper. Thus, there is a need for a fast, nondestructive analytical technique that leverages intrinsic attributes of the analytes. In this paper, we demonstrate an application of dielectric spectroscopy (DS) as a potential metrology to differentiate between nonwood pulp and wood pulp fibers. This in-situ, noncontact and nondestructive assessment method has inherent forensic capabilities and is also amiable to quality assurance techniques such as gauge capability studies and real-time statistical process control (SPC). Application: The dielectric spectroscopy results presented in this paper can nondestructively determine the amount of lignin in paper products and are in principle comparable to the performance specifications of the TAPPI Standard Test Method T 401 and should enable the sources of printing substrates to be both authenticated and validated in real time in a paper testing laboratory environment.

“…Bamboo lignin comprises p -coumaryl units with guaiacyl, syringyl and p -hydroxyphenyl moieties, similar to grasses, or Poaceae plant lignin (Banik et al 2017 ). Although bamboo lignins are richer in phenolic hydroxyl groups than wood lignins, and therefore more reactive during pulping (Vena et al 2010 ), no substantial change in Klason lignin content was observed upon bleaching the raw bamboo (Table 1 ).…”

Chemical composition of processed bamboo for structural applications

Natural materials are a focus for development of low carbon products for a variety of applications. To utilise these materials, processing is required to meet acceptable industry standards. Laminated bamboo is a commercial product that is currently being explored for structural applications, however there is a gap in knowledge about the effects of commercial processing on the chemical composition. The present study utilised interdisciplinary methods of analysis to investigate the effects of processing on the composition of bamboo. Two common commercial processing methods were investigated: bleaching (chemical treatment) and caramelisation (hygrothermal treatment). The study indicated that the bleaching process results in a more pronounced degradation of the lignin in comparison to the caramelised bamboo. This augments previous research, which has shown that the processing method (strip size) and treatment may affect the mechanical properties of the material in the form of overall strength, failure modes and crack propagation. The study provides additional understanding of the effects of processing on the properties of bamboo.

“…Banik et al . proposed that natural fiber composites are likely to be environmentally superior to glass fiber composites particularly in auto and structural construction applications . It is therefore anticipated that the use of natural fibers will appear an explosive growth in the development of next generation composites.…”

Biodegradable composites reinforced with natural fibers are emerging as advanced materials in structural applications. In this work, green biocomposites are fabricated using hot pressing molding technique, polylactic acid selected as a matrix. The samples are prepared with different fiber volume fractions (30%, 40%, and 50%). Tensile tests are conducted on the specimens to investigate the composite mechanical behavior, and the influences of fiber content on the morphological and thermomechanical properties are evaluated using scanning electron microscopy, differential scanning calorimetry, and thermogravimetric analysis. There are higher tensile modulus and lower elongation at break for composites with increasing fiber content, respectively. Much variation in the tensile strength is observed when the fiber content is varied, which could be attributed to fiber agglomerations that affect the dispersion of fibers in the matrix, as evidenced by fracture surfaces. Thermal tests demonstrate that the increment of fiber content enhances the glass transition temperature and crystallization temperature of composites. Besides, a comparative analysis of the composites is performed, and the properties of the treated fiber composites are found to be improved compared to those from untreated fibers. Detailed analysis confirms the possibility of the addition of bamboo fibers to a biodegradable matrix for a specific application. V C 2017Wiley Periodicals, Inc. J. Appl. Polym.
