Core-shell cylinder (CSC) nanotemplates comprising mussel-inspired catechol-containing triblock copolymers for silver nanoparticle arrays and ion conductive channels

Abstract

This is the first report on the synthesis of triblock copolymers containing catechol groups and it forms a core–shell cylinder phase, which can work as a template for Ag nanoparticle arrays and proton conduction.

Morphology-Controlled Mesopores with Hydrophilic Pore Walls from Triblock Copolymers

“…Similar morphology can be also observed in SEL20 (Figure f). Similar results were also observed by Yabu and co-workers Figure g shows the TEM micrograph of SEL40, in which disordered texture of PEO domains stained by PW can be observed, revealing the presence of network structures.…”

“…Similar results were also observed by Yabu and co-workers. 52 Figure 3g shows the TEM micrograph of SEL40, in which disordered texture of PEO domains stained by PW can be observed, revealing the presence of network structures. With more PW additive, lamellar structures can be found in SEL60 and SEL80 (Figures S6d and S6e).…”

Proton conductivity dependence on the surface polymer thickness of core–shell type nanoparticles in a proton exchange membrane

“…Silica@PVPA and silica@PVPA-b-PS were fabricated by RAFT PwP which performed RAFT/MADIX polymerization of PVPA under the coexistence of silica nanoparticles (Scheme 2). 33,34 Silica nanoparticles (1.0 g), VPA (0.45 g, 4.17 mmol), X 1 (9.3 mg, 41.8 mmol), AIBN (2.8 mg, 17.1 mmol), and DMF (3.0 g, 3.18 mL) were weighed in a test tube and irradiated with ultrasonic waves to disperse them. Later, nitrogen bubbling was performed and they were transferred to a nitrogen-lled glove box and polymerization was carried out at 65 C with stirring.…”

Progress on highly proton-conductive polymer thin films with organized structure and molecularly oriented structure

“…The proton conductivity was increased ten-fold by the addition of silver nanoparticles into the proton conduction channels filled with catechol moieties. He and his coworkers also reported proton conduction channels using mussel-inspired catechol-containing triblock copolymers composed of poly(methyl methacrylate), poly(vinyl catechol), and polystyrene [114]. The synthesized triblock copolymer formed a cylindrical organized structure in which poly(vinyl catechol) domains are located on the cylinder surface.…”
