The increasing antibiotic treatment failure is attributed to the increasing emergence of drug-resistant bacteria,and the attachment of these bacteria to the surface of implantation materials often leads to dangerous bacterial biofilm formation on the implant surface.Thus,this creates an urgent need to develop new antibacterial material and antifouling implants.Polydopamine (PDA),as a mussel-inspired material,has many advantageous properties,such as a simple preparation procedure,excellent hydrophilicity and biocompatibility,strong adhesive performance,easy functionalization,outstanding photothermal conversion effect,and strong quenching effect.PDA has increasingly attracted much interest not only for its adherence to virtually all types of surfaces but also as it provides a simple and versatile approach to functionalize material surfaces to obtain a variety of multifunctional nanomate-rials.In this review,we mainly focus on the preparation and polymerization mechanism of PDA systems and then provide a compilation of several reports on the PDA sur-face modification of various nanomaterials and material surfaces,including metals,metal oxides,carbons,and polymers.Finally,we summarize the advantages and dis-advantages of polydopamine surface-modified nanomaterials.

The composite of zeolitic imidazolate frame-works (ZIF-67) and ordered macroporous carbon (OMC)was successfully synthesized via in situ growth from the OMC matrix.The ZIF67-OMC composite was verified by scanning electron microscopy (SEM) and transmission
Inorganic photocatalysts have been regarded as a promising candidate in the domain of tumor photody-namic therapy (PDT) due to their inspirational photocat-alytic activity.In this study,a Bi4O5Br2 photocatalyst was synthesized and it exhibited effective p
The replacement of liquid electrolyte with solid electrolyte can significantly improve the safety and power/energy density of lithium batteries.70Li2S-30P2S5 is one of the most promising solid electrolytes with high con-ductivity for solid-state batteries
Further application of organic quinone cathodes is restricted because they are inherent in poor conductivity and tend to dissolve in aprotic electrolytes.Salinization can work on the strong solubility of quinones.Herein,the ortho-disodium salt of tetrahyd
In this paper,a visible light-responsive Sn2+and N co-doped TiO2 photocatalyst was prepared by facile one-pot hydrothermal method.All as-prepared samples were characterized in detail by a series of characterization approaches.The results showed that the S
Nano-silicon (nano-Si) and its composites have been regarded as the most promising negative electrode materials for producing the next-generation Li-ion batteries(LIBs),due to their ultrahigh theoretical capacity.How-ever,the commercial applications of na
Zn(CF3SO3)2 as an electrolyte has been widely used to improve the electrochemical performance for ZIBs due to that the bulky CF3SO3-can reduce the solvation effect of Zn2+ and promote the ionic diffusion.Herein,we found that Zn(CF3SO3)2 electrolyte can in
Combining the redox properties of Co and the acid properties of Nb in a Co3-Nb-Ox catalyst is shown to provide superior performance in the selective catalytic reduction of NO with NH3 (NH3-SCR).Co3O4 shows average activity,however,it exhibits a poor N2 se
An iridium/rhenium (Ir/Re) double-layer coat-ing was prepared on carbon/carbon (C/C) composites by chemical vapor deposition (CVD) and electrodeposition.The morphologies and bond strengths of the coatings on the C/C substrate were examined.The ablation re
The combination between biphasic calcium phosphate (BCP) and the osteomimetic porous micro-structure obtained via freeze casting is hoped to achieve excellent bone regeneration,while the effects of HA and β-TCP ratio changes on the degradation and biologi
