The team randomly grafted each polymer, one after another, onto a silicon wafer using a grafting-from approach to produce dense mixed-brush layers. "We observed that these binary brushes can be switched reversibly and repeatedly from a smooth, glassy brush layer to a spongy, gel-like rubbery layer by treatment in different solvents," Tsukruk told C&EN. "This reorganization of brush microstructure results in dramatic changes in surface elasticity. The elastic modulus changes 10-fold. The thickness, surface roughness, and macroscopic properties such as wettability and optical appearance also change dramatically." |
