Composites based on chitin (CH) biopolymer and metal-organic framework (MOF) microporous nanoparticles have been developed as broad-scope pollutant absorbent. Detailed characterization of the CH/MOF composites revealed that the MOF nanoparticles interacted through electrostatic forces with the CH matrix, inducing compartmentalization of the CH macropores that led to an overall surface area increase in the composites. This created a micro-, meso-, and macroporous structure that efficiently retained pollutants with a broad spectrum of different chemical natures, charges, and sizes. The unique prospect of this approach is the combination of the chemical diversity of MOFs with the simple processability and biocompatibility of CH that opens application fields beyond water remediation.
基于壳聚糖 (CH) 生物聚合物和金属-有机骨架 (MOF) 微孔纳米粒子的复合材料已被开发为广谱污染物吸收剂。对 CH/MOF 复合材料的详细表征表明，MOF 纳米粒子通过静电力与 CH 基质相互作用，诱导 CH 大孔的分隔，从而导致复合材料的总表面积增加。这就形成了一种微孔、介孔和大孔结构，能够有效地保留具有广泛不同化学性质、电荷和大小的污染物。这种方法的独特之处在于将 MOFs 的化学多样性与 CH 的简单加工性和生物相容性相结合，开辟了超越水修复的应用领域。
