“…Subsequent reaction to graft NH-terminated octadecyl (octadecylamine, ODA) on PDA films via Michael addition and Schiff-based reactions can introduce anti-water groups into BFs, which was a critical factor for building hydrophobic surfaces [9]. This long-chain alkylamine can also create hierarchical rough structures on BF surfaces, which can further enhance water resistance, as in lotus leaves [22]. Thus, hydrophobic BFs were eventually created.…”

“…The reason might be that bamboo is an intricate natural polymer composed of lignin and polyphenolic extracts, which may present many similar functional groups with polydopamine. Notably, the two characteristic peaks at 2920 and 2850 cm −1 for the PDA–BF and PDA/ODA–BF samples were attributed to –CH 3 and –CH 2 asymmetrical stretching vibrations and symmetric stretching vibrations from the PDA molecules, respectively [22], which proved that PDA-coating was successfully conducted. Moreover, in the PDA/ODA–BF spectrum, the doublets at 2920 and 2850 cm −1 were extremely high.…”

“…The characteristic peaks of the binding energy (BE) at 284.0 eV for the C–C and C–H species, 286.0 eV for the C–O species, 286.8 eV for the C=O and O–C–O species, and 288.5 eV for the O–C=O species were commonly observed on the other bamboo materials [32]. Interestingly, an additional peak appeared with BE located at 285.5 eV, which was ascribed to the C–N species from the as-coated PDA molecule [22]. Figure 3c,d presents the N 1s high resolution spectral lines of the PDA–BFs and PDA/ODA–BFs.…”

“…The anchored PDA coating consisting of massive catechol groups can act as a vigorous platform for large-scale diversities of secondary functionalized reactions, including tailoring metallic nano-coatings through in-suit reducing metal ions and grafting with amino-terminated monomers or polymers via Michael addition and Schiff base reactions [19]. In recent years, many advanced functional materials have been fabricated from conventional substrates, such as fabrics, sponges, and clay minerals, via mussel-inspired surface modification [20,21,22]. Zhu et al [23] tightly immobilized magnetic nanoparticles (Fe 3 O 4 ) on a sponge surface by using PDA as an intermediate.…”

Abstract:A new and eco-friendly mussel-inspired surface modification pathway for bamboo fiber (BF) is presented in this study. The self-assembly polydopamine (PDA) coating can firmly adhere on BF surface, which also serves as a bridge to graft octadecylamine (ODA) for hydrophobic surface preparation. The as-formed PDA/ODA hybrid layer could supply abundant hydrophobic long-chain alkyls groups and generated a marked increase in BF surface roughness and a marked decrease in surface free energy. These changes provided advantages to improve fiber-matrix interfacial adhesion and wettability. Consequently, high performance was achieved by incorporating the hybrid modified BF into the polybutylene succinate (PBS) matrix. The resultant composite exhibited excellent mechanical properties, particularly tensile strength, which markedly increased by 77.2%. Meanwhile, considerable high water resistance with an absorption rate as low as 5.63% was also achieved. The gratifying macro-performance was primarily attributed to the excellent interfacial adhesion attained by hydrogen bonding and physical intertwining between the PDA/ODA coating on the BF and the PBS matrix, which was further determined by fracture morphology observations and dynamic mechanical analysis. Owing to the superior adhesive capacity of PDA, this mussel-inspired surface modification method may result in wide-ranging applications in polymer composites and be adapted to all natural fibers.

Halloysite nanoclay (HNC) was mixed with Chitin hydrogel film by phase inversion in water vapor atmosphere at room temperature. In the preparation, Chitin was dissolved in N,N‐dimethyl acetamine/lithium chloride (DMAc/LiCl) and different amounts of HCN was dispersed well for the gelation process. The resultant Chitin‐Halloysite nanoclay (CTH) hydrogel films containing HCN at 0, 0.1, 0.5, 1, and 4 wt % were used for the adsorbents of heavy metal ions. As the results, the tensile strength of the hydrogel composite was enhanced from 0.34 to 0.71 N/mm2 while the elongation decreased from 66.43% to 49.93% with the increment of HNC concentration from 0 to 4 wt %. A reduction in the water content and the increment in the modulus confirmed the formation of highly dispersed nano‐composites with improved interfacial interactions between nano‐fillers and matrix. In the adsorption experiments of the ternary ion of Pb2+, Cu2+, and Cd2+, the removal capacity of Pb(II) was highly retained by the CTH hydrogel film relative to Cd(II) and Cu(II), shown Langmuir model with the maximum binding amount on the hydrogel composites were followed as order Pb (8.2 mg/g), Cu (4.2 mg/g), and Cd (2.1 mg/g). © 2018 Wiley Periodicals, Inc.

High‐capacity silicon anodes have attracted tremendous interest for next‐generation lithium‐ion batteries (LIBs). However, its further application is limited by the large volume expansion during cycling. Designing nanostructured silicon is an effective strategy to acquire high‐performance anodes, but it will face problems of high cost and poor coulombic efficiency. As a comparison, surface modification of micron silicon is more economically viable. Herein, a novel route is proposed to synthesize metal‐chelated biomimetic polyelectrolyte as a powerful binder, which wraps micron silicon particles in a thin Fe3+–polydopamine (PDA) layer with a thickness of 2–5 nm. The introduced Fe3+ can form powerful metal‐chelated bonds with PDA at appropriate hydrothermal temperature (160 °C). As a result, the mechanical strength of the protective layer is enhanced and the electrochemical activity of micron silicon is improved. Meanwhile, the 3D crosslinking structure formed through the esterification between the elastic polymer layer and polyacrylic acid (PAA) further guarantees the structural stability of anodes. Batteries using Si@Fe3+–PDA–160/PAA anode exhibit excellent cycling performance with stable capacity of 2000 mAh g−1 over 200 cycles at 0.5 C and high capacity retention ratio of 80% after 100 cycles at 0.1 C.
