| 摘 要： | A new method was proposed to prepare binary composite colloidal crystal hydrogels by interlocking the as-prepared polystyrene/sulfonated polystyrene core/shell colloidal crystal hydrogel with a second responsive gel. The shell thickness thus the core size were synchronously controlled by altering the sulfonation time and temperature. The proper monomers were radically polymerized forming the second gel within the first gel network. The composition and structure were confirmed. Nanopatterued hydrogel including porous bulk hydrogels and surface patterned hydrogels were derived by properly treating the binary composite hydrogels. Specially, some typical patterns such as arrays of “nano-bowls” ,arrays of “nano-ribbons” and “nano-mask” were achieved by changing the treatment method such as by immersion in the solvent, after solvent evaporation from the sample surface during high rate rotation. This work provides a method to prepare nanopatterued hydrogels. |
