摘      要：Smart-controlled surface wettability from superhydrophilicity to superhydrophobicity has been extensively explored,and stimulus-responsive strategies have been widely accepted as a useful method to realize ***,achieving smart and precise wetting control remains challenging because most previous studies focused on stimulating single surface chemistry or ***,a dualstimulus-responsive strategy that can synergistically stimulate surface chemistry and microstructures is demonstrated on the pH-responsive molecule poly(2-(diisopropylamino)ethyl methacrylate(PDPAEMA)-modified temperature-triggered shape memory polymer(SMP)*** responsive PDPAEMA and SMP can provide the surface with tunable surface chemistry and microstructures,***,the wetting of the surface between various states can be reversibly and precisely controlled from superhydrophilicity to superhydrophobicity with contact angle(CA)differences of less than 15° under the cooperative effect between the adjustable surface microstructure and *** surface is further utilized as a platform to create gradient wettings based on its excellent ***,this work presents a strategy for surface wetting control by combining tunable surface microstructures and *** prepared samples with a special wetting controllability can be applied to numerous fields,including adaptive liquid microlenses,accurate drug release,and selective *** work also proposes novel expectations in designing smart functional surfaces.
