“…The new absorption peaks found in the range of 380–450 nm proved the formation of conjugated structure caused by the Michael addition reactions between quinone moieties and nucleophiles (Figure 1d). [ 36 ] Data presented above shows that catechol groups could be oxidized by air in the hot pressing procedure without any additional oxidants. The formation of gel with a gel content of about 47.5% by putting the collected polymers after hot pressing in DMF further testified that the crosslinking reaction did occur in the adhesion process.…”

crosslinking [2,3] and metal ion chelation processes. [4,5] Thus, up to now, great efforts have been made to incorporate DOPA or catechol groups in a broad range of designed polymers to get mussel-inspired adhesives, which showed good bonding performances both at dry and underwater conditions. These polymers were generally named as "catecholfunctionalized polymers" (CFPs).Up to now, notable accomplishments have been achieved by using CFPs for high performance adhesion at atmospheric environment. Yu and Deming and co-workers reported the synthesis of DOPA-containing copolypeptides, exhibiting a bonding strength of 4.0 MPa on aluminum. [6] Wilker et al. synthesized poly[(3,4-dihydroxystyrene)-co-styrene] via anionic polymerization method, which achieved a bonding strength of 11 MPa on aluminum by using CaCO 3 particles as reinforcing materials. [7] Subsequently, they also incorporated the CFPs with poly(lactic acid) [8][9][10] or pendant oligo(ethylene glycol) moieties [4] to produce biodegradable/biocompatible adhesives with good dry-state bonding strength. Wan et al. synthesized catechol-functionalized poly(vinyl alcohol) via esterification reactions [11] and acetal formation reactions, [12] exhibiting bonding strengths of 4.0 MPa on glass and 14.9 MPa on stainless steel, respectively. Kaneko et al. synthesized a hyperbranched CFP via thermal polycondensation reaction between 3,4-dihydroxycinnamic acid and 4-hydroxycinnamic acid, which showed a bonding strength of ≈10 MPa on steel. [13] Then, they also prepared a similar hyperbranched polymer system with the bonding strength on steel up to 15 MPa. [14] However, despite great progress, the bonding strength of most reported CFPs on metal substrates is smaller than 15 MPa. Recently, Messersmith and co-workers [15] and Detrembleur and co-workers [16] separately reported the synthesis of catechol-functionalized polybenzoxazines and polyhydroxyurethanes, which were used to prepare thermoset adhesive materials with excellent bonding strength of 20.5 MPa on aluminum and 22.1 MPa on stainless steel, respectively. To our knowledge, these two polymers represent the best adhesive materials among CFPs for dry-state adhesion on metal Marine mussels have the ability to cling to various surfaces at wet or underwater conditions, which inspires the research of catechol-functionalized polymers (CFPs) to develop high-performance adhesive materials. However, these polymeric adhesives generally face the problems of complex synthetic route, and it is still high challenging to prepare CFPs with excellent adhesive performance both at dry and underwater conditions. Herein, a mussel-inspired alternating copolymer, poly(dopamine-alt-2,2-bis(4-glycidyloxyphenyl) propane) (P (DA-a-BGOP)), is synthesized in one step by using commercially available monomers through epoxy-amino click chemistry. The incorporation of polar groups and rigid bisphenol A structures into the polymer backbone enhances the cohesion energy of polymer matrix. The alternating polymer structure endows the polymers with high...

“…Monometallic hydroxides (e.g., nickel hydroxides and cobalt hydroxides) were usually synthesized under ambient conditions in air, which would lead to the inevitable oxidation of Ni 2+ or Co 2+ into their trivalent state. Therefore, positively charged Ni 3+ -doped Ni(OH) 2 and Co 3+ -Co(OH) 2 would be produced under the regular conditions from the transformation of monometallic hydroxides [78][79][80][81]. Although many studies have been devoted to monometallic Ni(OH) 2 -and Co(OH) 2 -based materials for OER, their electrocatalytic activity is still not satisfactory.…”

“…1 Self-assembly is a widely-accepted strategy for constructing nano-objects with diversified morphologies including spheres, worms, vesicles, and others. [2][3][4][5][6] Such a strategy is based upon the synthesized block copolymers and requires several necessary post-polymerization steps such as synthesis and purification before self-assembly process. 7 In addition, the traditional self-assembly is usually conducted at extremely low concentration of polymers.…”

Polymerization-induced self-assembly is a one-pot route to produce concentrated dispersions of block copolymer nano-objects. Herein, dissipative particle dynamics simulations with a reaction model were employed to investigate the behaviors of polymerization-induced self-assembly. The polymerization kinetics in the polymerization-induced self-assembly were analyzed by comparing with solution polymerization. It was found that the polymerization rate enhances in the initial stage and decreases in the later stage. In addition, the effects of polymerization rate, length of macromolecular initiators, and concentration on the aggregate morphologies and formation pathway were studied. The polymerization rate and the length of the macromolecular initiators are found to have a marked influence on the pathway of the aggregate formations and the final structures. Morphology diagrams were mapped correspondingly. A comparison between simulation results and experimental findings is also made and an agreement is shown. This work can enrich our knowledge about polymerization-induced self-assembly.
