Thermal insulation materials by recycling pulp and paper wastes play an important role in environmental sustainability of green buildings. As society is pursuing the goal of zero carbon emissions, it is highly desirable to use eco-friendly materials and manufacturing technologies for building insulation envelopes. Here we report additive manufacturing of flexible and hydrophobic insulation composites from recycled cellulose-based fibers and silica aerogel. The resultant cellulose-aerogel composites exhibit thermal conductivity of 34.68 mW m K, mechanical flexibility with a flexural modulus of 429.21 MPa, and superhydrophobicity with water contact angle of 158.72°. Moreover, we present the additive manufacturing process of recycled cellulose aerogel composites, providing enormous potential for high energy efficiency and carbon-sequestration building applications.
通过回收纸浆和纸张废料制成的隔热材料在绿色建筑的环境可持续性方面发挥着重要作用。随着社会追求零碳排放目标，使用环保材料和制造技术来构建建筑隔热围护结构是非常可取的。在此，我们报告了由回收的纤维素基纤维和二氧化硅气凝胶增材制造柔性和疏水性隔热复合材料。所得的纤维素 - 气凝胶复合材料的热导率为34.68 mW m⁻¹ K⁻¹，具有429.21 MPa的弯曲模量的机械柔韧性，以及158.72°的水接触角的超疏水性。此外，我们展示了回收纤维素气凝胶复合材料的增材制造过程，为高能效和碳封存建筑应用提供了巨大潜力。
