摘要：Recently,smart superwetting porous materials have aroused much attention,and it is well known that tunable surface wettability and pore structure/size are extremely important for their ***,only one factor can be regulated on existing materials,which significantly restricts their controllability,functions,and applications.A new material was prepared by electrodepositing a layer of polypyrrole on a shape memory sponge,on which switchable superhydrophobicity/superhydrophilicity and adjustable pore size within the range of about 28 nm to 895μm can be *** synergistically tuning the wettability and pore size,both ON/OFF water permeation and accurate flux can be ***,we also applied the sponge for molecule release,and diverse release manners with precise/smart controllability can be *** paper reports for the first time a smart material with controllability in both surface wetting and pore size,which provides a new strategy for the preparation of novel smart superwetting porous materials.
