“…The decrease in surface hardness is likely due to hemicellulose degradation caused by heating. Jiang et al [93] performed Copper naphthenate (CuN) impregnation and oil on bamboo specimens and observed that the application of CuN during heat-cold impregnation enhanced the termite resistance of bamboo significantly. Compared to the untreated control, heat oil treatment, and heat-cold impregnation of mineral oil alone, the CuN-treated round bamboo showed notable improvements in decay and mold resistance.…”

Bamboo is the building material of the past and future. It offers numerous properties that make it versatile for various applications, including construction. Its impressive strength-to-weight ratio enables it to bear substantial loads and stresses, while its good elasticity allows efficient energy absorption. However, its mechanical properties can vary based on factors such as species, age, locations, methods, and treatment. Treating bamboo is essential to enhance its properties and durability. The literature provides various natural and chemical treatments that enhance some of the properties but also reported drawbacks regarding higher temperature, content, and duration. This paper reviewed 57 articles from the Scopus database, specifically focusing on article–document-type publications from the years 2003 to 2023. Additional references were also incorporated to address concerns in properties, treatment, and standards to provide systematic understanding. With extensive assessment of the articles, the following gaps and concerns were observed, and recommendations for further study and assessment were made: the bamboo’s properties, the development of centralized guidelines and procedures for the preparation and processing; the exploration of alternative materials to reinforce bamboo without compromising its ductility; and the development of joint connections, and testing of mechanical properties considering seismic, wind and vibration. For treatment methods, the standardization of procedures using natural, chemical, or a combination. Lastly, for bamboo codes and standards, the assessment of existing codes and standards for testing the mechanical properties of bamboo, highlighting the potential limitations and areas, uniformity, and differences with all existing similar standards. By filling these gaps, it can support the reliability and robustness of bamboo as a sustainable material, fostering its promotion and adoption in the construction industry.

“…This process can enhance bamboo resistance to corrosion, cracks, and improve its overall appearance. Impregnation modification can also be employed to confer bamboo with fire resistance, insect repellent properties, energy storage, and other special characteristics, making it suitable for various specialized applications [57][58][59][60].…”

In light of continual societal advancement and escalating energy consumption, the pursuit of green, low-carbon, and environmentally friendly technologies has become pivotal. Bamboo, renowned for its diverse advantages encompassing swift growth, ecological compatibility, robust regenerative properties, commendable mechanical characteristics, heightened hardness, and abundant availability, has discovered applications across various domains, including furniture and construction. Nevertheless, natural bamboo materials are plagued by inherent limitations, prominently featuring suboptimal hydrophobicity and vulnerability to fracture, thereby constraining their broad-scale application. Thus, the paramount concern is to enhance the performance of bamboo materials through modification. However, prevailing reviews of bamboo modification predominantly concentrate on physical or chemical approaches, resulting in a conspicuous absence of a comprehensive overview of bamboo modification techniques. This review explores an array of bamboo treatment modalities and delivers a valuable assessment of bamboo modification, offering significant guidance for forthcoming bamboo enhancement and utilization endeavors.

Round bamboo has aroused much interest in construction for its mechanical properties, but poor biological durability seriously restricts its application. In order to develop a suitable and effective preservative treatment method for round bamboo, copper naphthenate (CuN) was adopted and impregnated into round bamboo using heat-cold procedure. The distribution and retention of copper naphthenate in round bamboo were studied, and the biological durability represented by the mould and decay resistance were investigated. The results showed that the retention and fixation of copper reached 0.39 kg⋅m −3 and 85.3%, respectively. Scanning electron microscopy–energy dispersive X-ray spectrometry further disclosed an increasing trend in the composition of CuN from the end inward. X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy analyses later revealed that CuN could be fixed on bamboo in the form of hydrogen bond or complex reaction. Statistical analysis showed that the increasing concentration of CuN from 0.3% to 0.5% and 0.8% (calculated as Cu 2+ content) has significant contribution against Trametes versicolor and Gloeophyllum trabeum in comparison with the untreated bamboo. Meanwhile, when the concentration of treating solution increased to 0.8 wt%, the resisting efficacy for Aspergillus niger , Penicillium citrinum and Trichoderma viride soared as high as 85.9%, 94.8% and 70.3%, respectively.
