In order to mitigate hazard of harmful microbes, the development of innovative antibacterial agents and materials became increasingly imperative. In this work, using acrylic thiazole (AcT) as hydrophobic/antibacterial monomer, zwitterionic betaine sulfonate (SBMA) as hydrophilic/antifouling groups, benzyl methacrylate (BM) as comonomer, and N , N -methylenebisacrylamide (NMBA) as cross-linking monomer, a novel thiazole-zwitterionic copolymer nanospheres (TZPNs) containing iso-bifunctional groups was designed and successfully synthesized through one-pot emulsion copolymerization in the system of dispersing agent (polyvinyl alcohol: PVA). The obtained nanospheres (TZPNs) were characterized by FT-IR, XPS, SEM, and DLS. Its antibacterial performance against Gram-positive of Staphylococcus aureus (S. aureus) and Gram-negative of Escherichia coli (E. coli) was systematically evaluated. It indicated TZPNs exhibits excellent antibacterial performance, and the inhibition rate was more than 99.9 % and the antibacterial mechanism with iso-bifunctional groups was also discussed. More importantly, its applications were extended to common materials, such as coatings, ink and dye. In summary, TZPNs was an excellent candidate for minimizing bacteria-infection in different functional materials and could be applied in different fields. [Display omitted] • A novel thiazole-zwitterionic copolymer nanosphere (TZPNs) was constructed by monomers with different functions. • TZPNs with iso-bifunctional groups could rapidly and effectively inhibit bacteria. • The inhibition rate was more than 99.9 % towards bacteria, and actual application. • The obtained TZPNs could be used as antibacterial agent in different fields including coating, dye and ink.

The overused of antibiotics had led to major environmental issues and drug-resistant bacteria, which inevitably harmed the environment and public health. In this work, in order to obtain environmentally friendly bi-functional materials to combat with residual antibiotics and bacterial contamination, ZIF-8, a typical Zn based zeolitic imidazolate framework (ZnZIF) with excellent chemical stability, was conjugated to hydroxyapatite nanowire bundles (HAnBs) by a simple in-situ synthesis. The obtained ZnZIFs@HAnBs was characterized by SEM, EDS, XPS, FT-IR, XRD and BET. The effects of catalysts, catalyst dosage, TC initial concentration, PMS concentration and pH on TC degradation were investigated. Notably, ZnZIFs@HAnBs (94.0 %) exhibited excellent degradation effect of tetracycline (TC) within 15 min, which was 1.7 and 5.2 times than that of ZIF-8 (55.9 %) and HAnBs (18.1 %) under optimal conditions, respectively. Moreover, after recycling 10 times, the degradation rate still more than 86.8 %. The degradation mechanism was confirmed by free radical quenching experiment coupling with electron paramagnetic resonance (EPR), and the 1O 2 and O 2 •- were the major reactive oxygen species in TC degradation. Furthermore, it presented excellent antibacterial activity (95.0 %) against E. coli and S. aureus , which was attributed to the synergistic effect of sustained release of Zn2+ and phosphate in ZnZIF@HAnBs. In summary, an eco-friendly bi-functional materials of HA nanowire bundles could be synthesized by simple strategy, and it could be applied in the fields of environmental remediation, as well as in treatment of antibiotic and bacterial pollution. [Display omitted] • ZnZIF@HAnBs was successfully synthesized by a simple in-situ synthesis method. • It could quickly degrade tetracycline, and the degradation rate got to 94.0 %. • The catalyst has excellent reusability, stability and degradation universality. • It formed a Zn3+/Zn2+ cycling system, which 1O 2 and O 2 •- play an important role. • The antibacterial rates of ZnZIF@HAnBs against bacteria reached 95.0 %.
