“…The explanation was the stronger interfaces between the ller and the resin giving rise to higher breakdown strength. Similar modications were conducted on boehmite nanoparticles 38 and carbon bers, 39 and both the modied llers demonstrated good affinity to epoxy resin.…”

“…Consequently, for weak oxidants such as oxygen, polymerization is very slow under neutral conditions increasing to a maximum between pH 8.5 and pH 10, with alkalinity ≧ pH 10.1 totally suppressing polydopamine coating formation . Stronger oxidizing agents such as ozone and sodium periodate accelerate the polymerization of dopamine under basic conditions. This provides up to a ≈200‐fold increase in coating rate for a 2:1 stoichiometric ratio of periodate to dopamine; fast enough to allow spray coating of polydopamine .…”

“…Dopamine has also been modified with l ‐cysteine to create 5‐S‐cysteinyldopamine, which has been polymerized on its own and with polydopamine to make synthetic pheomelanin . Another example of dopamine modification is its reaction with 1,3‐propane sultone, making a sulfonate variant that has been used to present a negatively charged coating surface to allow better dispersion of coated particles …”

“…This has led to the fillers improving various physical properties of the final composites. For example, polycatecholamines have been used to bind reinforcing agents (boehmite nanoparticles, barium titanate nanoparticles, halloysite nanotubes, silver nanoparticles, short Kevlar fibers, bioactive glass particles, glass fiber, carbon fiber, reduced graphene oxide, and carbon nanotubes) to the bulk polymer to improve mechanical properties. Other examples include polydopamine coated boron nitride nanoparticles and carbon nanotubes used to improve composite thermal conductivity; polydopamine coated halloysite nanotubes, used to enhance the proton conductivity of proton exchange membranes; polydopamine coated metallic nanoparticles used to increase electrical conductivity; and polydopamine used to incorporate carbonyl iron microparticles and magnetite nanoparticles into composites used for microwave absorption.…”

Almost ten years ago, Lee et al. [13] formulated a universal adhesive coating based on observation of the strong attachment by mussels through their byssal threads to virtually all types of inorganic and organic surfaces. The amino acid compositions of the mussel foot proteins that generate the attachment are rich in catechol and amine groups. [13][14][15] These groups associate under marine conditions, forming strong covalent and noncovalent interactions with substrates. [13] This led to the idea that both catechol and amine groups were crucial in forming robust, wide spectrum adhesive nanolayers [16,17] and consequently dopamine was conceived as a powerful building block for spontaneous deposition of thin polymer films. The dopamine monomer is deposited onto unadulterated surfaces through self-assembly and oxidative cross-linking from mild pH aqueous solution in a rapid reaction. This results in a durable, nanoscale, conformal, and hydrophilic coating that can be readily modified to introduce specific surface chemistries for a particular application. [18][19][20][21][22] These bioinspired, polydopamine materials are chemically and structurally indistinguishable from eumelanins found in the human body, [23,24] providing excellent biocompatibility. Additionally, polydopamine has broad electromagnetic absorption and excellent photothermal energy conversion [25] as well as having ionic-electronic hybrid conductivity. [26] Along with the excellent coating performance, these properties provide a vast array of potential applications for polydopamine materials.In this article, we explain what is known about polydopamine and related catecholamine coatings; their formation, the adhesion mechanism, and their physicochemical properties and we also review the applications of these materials (Figure 1). Since 2011, there have been a number of reviews on this subject matter, including general reviews on the physicochemical properties of polydopamine coatings [11,20,[27][28][29] and their applications. [20,27,30] There are also a number of more specific reviews on the chemical synthesis and modulation of polycatecholamine coatings, [31] the biomedical applications of these coatings, [8,[32][33][34] their electronic properties, [26,35] the use of polydopamine to make films at fluid interfaces, [36] in hierarchically constructed particles, [33] and capsules, [30] exploitation of polycatecholamine coatings in membrane filtration, [37] polydopamine-derived carbon materials, [38] and the use of coordination chemistry in catechol-based materials. [39] Nonetheless, this area of research is growing so rapidly [25,27] that many recent Polydopamine and related polycatecholamines can be easily deposited onto almost any surface from mild, aqueous solution. This results in durable, nanoscale coatings that exhibit high biocompatibility and have useful chemical and electronic properties. Additionally, these materials can be readily chemically and physically modified, and consequently, they are used extensively for surface modification. This ...

“…Among these, nano‐TiO 2 (the following is referred to as TiO 2 ) is expected to provide great potential in WPUs reinforcement. However, owing to the aggregation of inorganic nanoparticles (NPs), the dispersion quality of NPs in WPUs is limited . To intensify the compatibility between TiO 2 and WPUs, it is still highly desirable to take some efficient measures to improve the dispersion of TiO 2 in WPUs and reinforce interfacial interaction, thus improving the mechanical properties and thermal stability of polymer composites.…”

Environmentally friendly waterborne polyurethane (WPU) films were functionalized by incorporating nanotitanium dioxide (TiO 2 ). In order to improve the dispersion of TiO 2 in the WPU matrix and intensify the interfacial interaction between TiO 2 and WPU, green and biocompatible dopamine (DA) modified TiO 2 , that is, DA-TiO 2 , was produced. Fourier transforms infrared (FTIR) and UV-vis spectra confirmed that DA had been successfully grafted on the surface of TiO 2 . The structure, mechanical and thermal properties of WPU/DA modified TiO 2 (WPU/DA-TiO 2 ) films had been carefully investigated using FTIR, transmission electron microscopy (TEM), X-ray diffraction (XRD), tensile experiments and thermogravimetric analysis (TGA). The tensile strength and elongation at break of WPU/ DA-TiO 2 containing 1 wt% DA-TiO 2 increased by 56.8% and 37.0%, respectively, compared to pure WPU. These results can be ascribed to the good dispersion of DA-TiO 2 and the strong interfacial interaction between DA-TiO 2 and WPU matrix. In addition, the thermal properties and water resistance of WPU/DA-TiO 2 films also had been improved. POLYM. COMPOS., 00:000-000,
