Environment‐Adopting Surfaces with Reversibly Switchable Morphology

Preparation and characterization of V-shaped PS-b-PEO brushes anchored on planar gold substrate through the trithiocarbonate junction group

“…The microphase-separated pattern of the mixed brush may lead to some particular properties of the surface in lubrication, friction, adhesion, and wettability [9][10][11]. Secondly, the mixed polymer brush is responsive to environmental stimuli, such as solvent atmosphere, and thus the surface composition and morphology of the mixed polymer brush is variable [12][13][14][15][16][17]. As a result, the surface properties of the mixed polymer brush can be tuned or switched by applying external stimuli [18][19][20][21][22][23][24][25][26][27][28][29].…”

Amphiphilic copolymer grafted “smart surface” enhanced by surface roughness

“…However, for a smart surface prepared on a flat surface, the responsive range is relatively narrow [21][22][23][24][25][26], which might have fatal limitations for applications. How to make a responsive surface, which switches in a wide range of wettability between hydrophilic and hydrophobic states, especially between superhydrophilic and superhydrophobic states, is still a challenge.…”

Surface-initiated controlled radical polymerizations from silica nanoparticles, gold nanocrystals, and bionanoparticles

“…Generally, different combinations of surface-initiated ATRP, surface-initiated reverse ATRP, surface-initiated RAFT polymerization, surface-initiated NMP, and surface conventional free radical polymerization can be utilized in a grafting-from procedure to fabricate mixed brushes from a surface. 102,208,[250][251][252][253][254] However, this approach has intrinsic disadvantages. Since different species of initiators have to be attached to the substrate simultaneously or sequentially, uncontrollable preferential binding of one species, inhomogeneous distribution of the grafting initiators, and disordered phase separation in whatever scale cannot be avoided.…”
