Abstract Light irradiation is an external stimulus, rapidly developed in switchable atom transfer radical polymerization (ATRP) via photo-activation methods in recent years. Herein, we introduce a photo-deactivation strategy to regulate ATRP with the assistance of photoswitchable hexaarylbiimidozole (HABI). Under visible light irradiation and in the...
Cs3Sb2Br9 perovskite nanoparticles are employed as a lead-free photocatalyst for light-controlled atom transfer radical polymerization. The Cs3Sb2Br9 nanoparticles, characterized by a high reduction potential, efficiently interacted with bromide initiators through Lewis acid Sb sites, facilitating the photoinduced reduction of initiators and enabling...
This study highlights temperature-adaptative self-oscillating gels with broad operating temperature regions. The gels consist of nonthermoresponsive monomers, primarily N,N-dimethylacrylamide or 2-acrylamido-2-methylpropane sulfonic acid. These gels exhibit robust self-volume oscillation at 20.0, 27.0, and 36.5 °C: temperature adaptation on environmental...
This study presents the synthesis of polysulfide particles in diverse sizes utilizing phase transfer catalysts and polymeric stabilizers, contrasting with prior research. Particularly notable is the one-step growth of polymer particle size by more than 1 µm. The resultant polysulfide segments exhibit size-dependent antioxidant effects, suggesting...
This work presents an in situ polymerization-induced microphase separation strategy via random copolymerization for constructing ionogel electrolytes for high-performance flexible electrochromic devices. The in-situ formed ionogels exhibit excellent mechanical properties and are highly adhesive on various substrates, endowing the electrochromic devices...
In recent years, the need to quantify the softness of colloidal particles with sizes of few hundreds of nanometers has become pivotal for both theoretical studies and applications. Particle compressibility plays a crucial role in determining the overall material's properties, especially in concentrated suspensions. This study demonstrates the capability...
