Multifunctional Hydrogels with Reversible 3D Ordered Macroporous Structures
Hydrogels are synthetic or natural polymer networks crosslinked either chemically or physically to maintain 3D
structures that are able to absorb and retain large amounts of water. [ 1 ] Porous biocompatible hydrogels combine porosity with biocompatibility and play an important role in various biomedical applications, such as scaffold materials in tissue engineering, cell transplantation, and regenerative medicine. [ 2 ] The properties of porous hydrogels are substantially infl uenced by the porosity related parameters, including surface area,pore size, pore interconnectivity, interfacial properties, etc. [ 3 ]Therefore, rational design of hydrogels with desired structures
and properties is an essential requirement for advanced technological applications. The properties can be additionally programmed by modifi cation of functional porous hydrogels
