摘要
Super-amphiphilic (highly oleophilic and hydrophilic) materials have attracted tremendous interest for fundamental research and potential applications, owing to their unique affinity for both oil and water. In this work, a novel super-amphiphilic porous polycaprolactone (PCL) was fabricated via an efficient and eco-friendly method, in which stearic acid (SA) was used as both a porogen and a dopant precursor. The porous PCL had an interconnected hierarchical pore structure and was capable of absorbing oil and water rapidly. The complementary cooperation of the oleophilic and hydrophilic domains on the pore surface induced the amphiphilicity, while the capillary forces caused a wicking action. The synergy of the two effects gave rise to the super-wetting property. The special amphiphilic feature of the porous PCL had a positive effect on its biocompatibility and the material can be considered as a promising candidate for tissue engineering applications.
