“…An absorption band has been observed near about 3344 cm −1 for all types of treated and untreated bamboo fiber due to OH groups' stretching vibration presented in lignin, hemicellulose and cellulose components. The stretching vibrations of CH groups in lignin and cellulose [ 9 ] have produced another band at 2914 cm −1 wave numbers for all samples. A spike has been observed at 1731 cm −1 wave numbers due to vibration of stretching types of CO group presented in hemicellulose.…”

“…More than 70 genera and 1000 species of bamboo are found in Asia and South America, and all grow naturally in different climates. [ 9 ] Tingju Lu et al [ 10 ] prepared a composite by using bamboo cellulose and PLA. Adding bamboo cellulose inside the polymer matrix decreased tensile strength by 8% and increased tensile modulus by 11.76%.…”

“…However, due to strips are non‐flexible in nature so it is difficult to develop complex shapes by using extracted bamboo strips; whereas due to the flexible nature of fiber it is quite easier to develop irregular shapes with fiber reinforcement. Moreover, Saha and Kumari [ 9 ] have reported that in the northeastern part of India (Assam region), Bambusa tulda is one of the unexplored bamboo species. However, this bamboo is used to develop local products and support the construction industry.…”

In recent years, sustainable composites have gained increased attention due to various reasons, such as the depletion of non‐renewable resources, environmental sustainability, and the introduction of plastic pollution. The present work aims to develop biocomposites (with a maximum biological content of 61.78%) based on Bambusa tulda fiber and cashew‐nut shell oil‐based bio‐epoxy resin. Different concentrations of NaOH (2%, 4%, 6%, 8%, and 10%) are used to determine the most suitable NaOH concentration for bamboo fiber treatment. The effect of different treatment concentrations on bamboo fiber has been analyzed by performing single‐fiber tensile testing, fiber pull‐out testing, X‐ray diffraction (XRD), Fourier transform infrared spectroscopy, thermogravimetric analysis, and atomic force microscopy. The investigation revealed that the 6% NaOH‐treated fiber showed better thermo‐mechanical and interfacial properties. Various fiber weight fractions (10%, 20%, 30%, and 40%) are used for composite fabrication, and 30% fiber‐loaded composites show the best mechanical properties. The effect of chemical treatments on the mechanical properties of biocomposites was investigated using composites with a 30% fiber weight fraction and different NaOH treatments. It has been reported that 30% fiber weight fraction 6% NaOH treated composites show better tensile strength (132.916 MPa), tensile modulus (6.983 GPa), flexural strength (154.8 MPa), modulus (8.243 GPa), and impact strength (44.06 kJ/m2) with less moist absorption. The developed composites have shown excellent potential for advanced engineering applications when compared with previously reported composites.

An increasing trend in creating materials with a greater extent of sustainability from an ecological and financial perspective involves usage of bio resources and industrial residues. In this paper, leftover bamboo micro particles (BMP) from bamboo factories were collected and used as fillers with polyvinylidene fluoride (PVDF) matrix in varying concentrations (1, 3, 5, 7, and 9 wt.%) to fabricate low-cost composite films using solvent casting route for mechanical energy harvesting purpose. Out of the prepared samples, PVDF with 5 wt.% BMP showed maximum electroactive phase content (82%), tensile strength (34.23 MPa), and piezoelectric voltage (6.5 V) among the untreated samples. PVDF with 5 wt.% BMP is then subjected to NaOH treatment for further enhancement in overall performance. PVDF with 5 wt.% treated BMP also showed 467% increment in output voltage and 235% increment in output current as compared to pure PVDF. The piezoelectric output voltage of PVDF with 5 wt.% treated BMP is then measured under impact loading conditions to determine its suitability as an impact sensor. A bamboo-based piezoelectric impact sensor that is highly sensitive and cost-effective opens enormous possibilities for sustainability and circular economies.
