“…The process is simple, environmentally friendly, and cost-effective. Moreover, the rich functionality of PDA provides many active sites for subsequent modification of the substrate; thus, PDA has received considerable attention. − For example, Nuo Xu et al deposited PDA on the surface of carbon fiber (CF) and exploited the strong adhesion to prepare the CF-PDA@Ag composite material with greatly improved mechanical properties; Dan Song et al utilized the strong adhesion of the PDA coating, abundant catechol functional groups, and the binding ability of horseradish peroxidase to prepare the MCNCs@PDA nanocomposite, which had an ultrahigh adsorption capacity …”

Highly efficient and reusable protective materials for chemical warfare agents (CWAs) are in high demand. Here, we used a surface modification technique to develop a material that provides chemical protection. Using an electrospun polyacrylonitrile (PAN) nanofiber membrane as the substrate, we modified the surface of the nanofiber with dopamine hydrochloride, which self-polymerized to form a polydopamine (PDA) surface layer, onto which we loaded metal–organic framework (MOF-808) particles. The presence of PDA on the surface of the PAN nanofibers significantly increased the breaking strength (2-fold increase) and elongation (9-fold increase) of the nanofiber membrane. Moreover, the PDA functionalities formed coordination sites to trigger the in situ growth of MOF-808 particles on the surface of the nanofiber membrane, thereby considerably increasing the growth rate and loading capacity. The surface of the nanofiber membrane was completely covered with MOF-808 particles following solvothermal treatment for 16 h. The MOF-808/PAN/PDA composite membrane could rapidly degrade 99.9% of dimethyl-4-nitrophenyl phosphate to p-nitrophenol within 8 min. After the membrane was used several times, the conversion rate stabilized at 95.9%, indicating that the MOF-808/PAN/PDA composite membrane has significant potential for application as protective clothing for CWAs.
