An amino functionalized paper-based material that utilized amino functionalized polymer particles as sensing probes and adsorption sites was fabricated via internal sizing technology for application in formaldehyde detection and adsorption. A large specific surface area and the porous structure of the paper fibers enable the application of the composite paper-based material as a sensor at low concentrations of primary amine groups. The material reacts with low levels of formaldehyde, resulting in a concentration-based change in the pH, which is rapidly expressed as a color change. After exposure to formaldehyde (0.02 mg/m3) for 10 min, the color of the composite paper-based material changed from pink to brown, demonstrating the high sensitivity of the material, and this transition could be clearly observed using the naked eye. Additionally, the composite paper-based material acts as an adsorbent at a high content of amino groups, owing to a rapid addition reaction with formaldehyde, exhibiting a high adsorption capacity. Considering the high sensitivity, adsorption capacity, and adsorption speed for formaldehyde, the as-developed composite paper-based material exhibits promising application potential in the field of formaldehyde detection and adsorption.

用于高效检测和吸附甲醛的氨基功能化纸基材料的制备
通过内部施胶技术制备了一种氨基功能化纸基材料，该材料利用氨基功能化聚合物颗粒作为传感探针和吸附位点，用于甲醛检测和吸附。纸纤维的大比表面积和多孔结构使得复合纸基材料能够作为低浓度伯胺基团的传感器应用。该材料与低含量的甲醛发生反应，导致 pH 值发生浓度变化，并迅速表现为颜色变化。暴露于甲醛（0.02 mg/m 3 ）10分钟后，复合纸基材料的颜色从粉红色变为棕色，证明了材料的高灵敏度，并且用肉眼可以清楚地观察到这种转变。此外，复合纸基材料在高氨基含量下可作为吸附剂，由于与甲醛的快速加成反应，表现出高吸附能力。考虑到对甲醛的高灵敏度、吸附容量和吸附速度，所开发的复合纸基材料在甲醛检测和吸附领域表现出广阔的应用潜力。
