Controllable Wet-Brush Blending of Linear Diblock Copolymers with Phenolic/DDSQ Hybrids toward Mesoporous Structure Phase Diagram

“…Self-assembled structures such as typical lamella (LAM), hexagonal packing cylinder (HPC), sphere, double gyroid (DG), and even special Frank–Kasper phases of immiscible diblock copolymers (BCP) have been widely investigated during recent years because of their potential applications including soft lithography, photonic crystals, nanocomposites, and mesoporous materials. − The synthetic strategies of BCP with composition and structural variety are mainly from sequential addition of monomer through controlled living polymerization techniques or coupling reactions from the active chain ends with two different polymer chains. − It is well-known that the self-assembled structures are primarily dependent on the volume fraction, interaction parameter (χ), and degree of polymerization ( N ); however, mediating the volume fraction is complicated and time-consuming through the controlled living polymerization . As a result, blending homopolymer (A or B) into an A- b -B diblock copolymer is a relatively simpler method to mediate different self-assembled structures for varying volume fractions …”

The Development of Visible-Light Organic Photocatalysts for Atom Transfer Radical Polymerization via Conjugation Extension

“…The advantage of light as an external stimulus to regulate the polymerization process includes the non-invasive mediation, high energy efficiency, spatiotemporal control, wide availability, and easy access to inexpensive, long-wavelength LED light sources [ 3 ]. In particular, the corresponding visible light-mediated RDRP offers photocontrol technologies enabling temporal and spatial regulation of chain growth, a capability not attainable in conventional thermally activated and chemically activated processes [ 4 , 5 ]. As one of the most powerful and versatile RDRP techniques, atom transfer radical polymerization (ATRP) [ 6 , 7 ] has gained significant advances in the past years by uniting light regulation, and the corresponding photocontrolled ATRP (photo-ATRP) routes not only allow for the precise control of reaction kinetics but also facilitate the fabrication of advanced materials [ 8 , 9 , 10 ].…”

Thermoresponsive Copolymers with Well-Defined Composition and Phase Separation Via Semi-Batch Free-Radical Polymerization in a Non-Polar Medium

“…Two main behaviors have been reported, according to whether this sharp change in the solubility occurs by decreasing or increasing the environment temperature. In the former case, the binodal curve of the T cp as a function of the polymer volume fraction in the mixture has a maximum defined upper critical solution temperature (UCST), while in the latter the binodal curve shows a minimum defined lower critical solution temperature (LCST). − This smart and controllable behavior opened up a plethora of applications in sectors as diverse as oil and gas, − sensors, , and in particular biomedicine, − where thermoresponsive polymers are enabling fascinating and previously unexplored possibilities in tissue engineering and regenerative medicine.…”
