Sugarcane, as one of the most important crops in the world, plays an important role in the economy around the world. However, huge waste and low treatment efficiency put forward new requirements for bagasse treatment. Herein, a wearable eco-friendly cellulose-based hybrid membrane was fabricated with a view to recycling bagasse. Specifically, the bagasse cellulose was extracted from waste bagasse, and the CNT/cellulose@Ag nanoparticles (CCAgNP) hybrid membrane was obtained by magnetron sputtering and blending method. The CNT/cellulose membrane obtained by doping CNTs in cellulose dispersion suspension is abbreviated as CCM. The results indicated that benefiting from the high infrared reflectance (0.82) of the AgNP side and the fast absorbance (1.5) of the CCM side, the CCAgNP can achieve a dual thermal insulation due to the synergistic effect of two sides of the membrane. In addition, the asymmetric wettability of both sides of the hybrid membrane enables sweat to be transported unidirectionally, keeps the skin on the surface of the human body dry, and achieves wearing comfort. More importantly, the hybrid membrane also shows the excellent antibacterial property, air permeability, mechanical property and thermal stability, providing good support for the practical application of the hybrid membrane. This study shows that the fabrication of hybrid membranes with integrated functionalities can be extended for the fabrication of other wearable materials from agricultural wastes for various applications.

一种源自废弃甘蔗渣的环保纤维素基杂化膜,用于可穿戴应用
甘蔗作为世界上最重要的农作物之一,在世界经济中发挥着重要作用。然而,巨大的废弃物和低处理效率对甘蔗渣处理提出了新的要求。在此,为了回收甘蔗渣,制造了一种可穿戴的环保纤维素基杂化膜。具体而言,从废弃甘蔗渣中提取甘蔗渣纤维素,通过磁控溅射共混方法得到CNT/纤维素@Ag纳米颗粒(CCAgNP)杂化膜。在纤维素分散悬浮液中掺杂碳纳米管而得到的碳纳米管/纤维素膜,简称CCM。结果表明,受益于AgNP侧的高红外反射率(0.82)和CCM侧的快速吸收率(1.5),由于膜两侧的协同效应,CCAgNP可以实现双重隔热。此外,混合膜两侧的不对称润湿性使汗液能够单向输送,保持人体表面皮肤干爽,实现穿着舒适。更重要的是,杂化膜还表现出优异的抗菌性能、透气性、力学性能和热稳定性,为杂化膜的实际应用提供了良好的支撑。这项研究表明,具有集成功能的混合膜的制造可以扩展到从农业废物中制造其他可穿戴材料,用于各种应用。混合膜两侧的不对称润湿性使汗液单向输送,保持人体表面皮肤干爽,实现穿着舒适。更重要的是,杂化膜还表现出优异的抗菌性能、透气性、力学性能和热稳定性,为杂化膜的实际应用提供了良好的支撑。这项研究表明,具有集成功能的混合膜的制造可以扩展到从农业废物中制造其他可穿戴材料,用于各种应用。混合膜两侧的不对称润湿性使汗液单向输送,保持人体表面皮肤干爽,实现穿着舒适。更重要的是,杂化膜还表现出优异的抗菌性能、透气性、力学性能和热稳定性,为杂化膜的实际应用提供了良好的支撑。这项研究表明,具有集成功能的混合膜的制造可以扩展到从农业废物中制造其他可穿戴材料,用于各种应用。机械性能和热稳定性,为杂化膜的实际应用提供了良好的支撑。这项研究表明,具有集成功能的混合膜的制造可以扩展到从农业废物中制造其他可穿戴材料,用于各种应用。机械性能和热稳定性,为杂化膜的实际应用提供了良好的支撑。这项研究表明,具有集成功能的混合膜的制造可以扩展到从农业废物中制造其他可穿戴材料,用于各种应用。
