纤维素纳米材料是天然存在的，具有独特的结构、机械和光学性质。虽然造纸和包装，汽车，个人护理，建筑和纺织行业已经认识到纤维素纳米材料的潜力，但我们认为纤维素纳米材料在水处理技术中具有巨大的未开发潜力。在这篇综述中，我们收集了纤维素纳米材料在环境修复和水过滤膜中的有益作用的证据，包括它们的高表面积与体积比，低环境影响，高强度，功能化和可持续性。我们在物理和化学性质、生产成本、使用和处置方面对纤维素纳米材料和碳纳米管（CNTs）进行了直接比较，以显示纤维素纳米材料在水处理技术中作为CNT的可持续替代品的潜力。最后，我们评论需要改善在纤维素纳米材料生产和开发中投资的众多行业之间的沟通和合作，以实现商业化的有效手段。
Cellulose nanomaterials are naturally occurring with unique structural, mechanical and optical properties. While the paper and packaging, automotive, personal care, construction, and textiles industries have recognized cellulose nanomaterials’ potential, we suggest cellulose nanomaterials have great untapped potential in water treatment technologies. In this review, we gather evidence of cellulose nanomaterials’ beneficial role in environmental remediation and membranes for water filtration, including their high surface area-to-volume ratio, low environmental impact, high strength, functionalizability, and sustainability. We make direct comparison between cellulose nanomaterials and carbon nanotubes (CNTs) in terms of physical and chemical properties, production costs, use and disposal in order to show the potential of cellulose nanomaterials as a sustainable replacement for CNTs in water treatment technologies. Finally, we comment on the need for improved communication and collaboration across the myriad industries invested in cellulose nanomaterials production and development to achieve an efficient means to commercialization.
