To enhance the hydrophobicity of bamboo surfaces, nano-biomimetic technology is employed to transfer the micro-nano papillae structure found on lotus leaves onto bamboo. This technique uses elastic molds or seals, typically made of silicon-based materials like polydimethylsiloxane, to replicate the micro- and nano-structures of plant leaves onto specific substrates. After solidification, these substrates acquire a microstructure and functionality similar to that of the original plant leaves. These experiments confirm that under the observation of the surface of bamboo materials with simulated plant leaf micro- and nano-structures synthesized through soft printing technology, they have micro-papillary structures and rough surfaces similar to the original plant leaves. The surface of bamboo with a micro- and nano-structure resembling plant leaves exhibits superhydrophobic properties, with a water contact angle greater than 150°. Introducing this superhydrophobic property into the local material bamboo enhances its waterproof and moisture-proof functions. This combination can promote the widespread application of local materials in modern architecture and enhance their value in the microrenewal construction of the Grand Canal National Cultural Park. By protecting and preserving Yangzhou’s cultural heritage, integrating these advancements can enhance the park’s overall quality and allure, providing visitors with a more immersive experience. Additionally, these research findings serve as a valuable reference and source of inspiration for similar cultural heritage protection projects, thus promoting the continued growth and development of China’s rich and diverse historical and cultural heritage.
