Abstract

The extensive use of plastic pipes has brought about severe environmental pollution and posed risks to human health, thereby giving rise to an urgent need for the development of environmentally friendly alternatives. Herein, a tough, eco-friendly, and biodegradable cellulose pipe (BCP) is reported. The preparation involved dissolving and casting cellulose into membranes, followed by bonding, and shaping the membranes through sodium alginate to create cellulose pipes. Owing to its highly ordered molecular structure and low-density characteristics, the as-prepared BCP exhibited a specific modulus of 24.65 MPa cm³ g⁻¹, which surpassed that of commercial plastic-based pipes, such as ABS, PA, and PE. Furthermore, the BCP demonstrated high deformation adaptability, effectively maintaining water flow performance in complex environments and thus enhancing agricultural productivity. Notably, the BCP can be completely degraded within 49 days, meeting the requirements for practical use. This excellent biodegradability makes the pipe fabricated from natural plant-based materials an environmentally friendly alternative to plastic pipes.

高韧性、低内应力、自降解的环保全生物质管道，用于农业可持续灌溉

塑料管道的广泛使用带来了严重的环境污染，对人类健康构成了威胁，因此迫切需要开发环境友好的替代品。本文报道了一种坚韧、环保、可生物降解的纤维素管（BCP）。制备过程包括将纤维素溶解并浇铸到膜中，然后结合，通过海藻酸钠塑造膜以形成纤维素管道。由于BCP具有高度有序的分子结构和低密度特性，其比模量为24.65 MPa cm3 g−1，超过了ABS、PA和PE等商用塑料基管材。此外，BCP表现出高度的变形适应性，可以有效地维持复杂环境下的水流性能，从而提高农业生产力。值得注意的是，BCP可在49天内完全降解，满足实际使用要求。这种优异的可生物降解性使得由天然植物材料制成的管道成为塑料管道的环保替代品。图形抽象

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
