Description

There is a world-wide effort to prepare self-cleaning slippery surfaces for various applicationsincluding keeping clothing clean from stains, planes free from ice, and artificial blood vesselsfree from clotting. Similar to many other materials, a common problem of slippery surfaces istheir mechanical robustness, as they typically fail due to abrasion. Recent application of self-healablesupramolecular materials makes it possible to improve mechanical durability of theslippery surfaces. However, the research of self-healable slippery surfaces is in the earlydevelopment stage. Although the healing process of current supramolecular materials can becompleted in a few minutes, the process is not spontaneous. Within such a time gap, the potentialattachment of foulants around/in the damaged area may make the restoration of surface functioncomplicated.This project aims to gain a systematic understanding on the synergy of material healing, interfacerestoration and biofouling prevention. We propose to develop a series of self-healable slipperynanocomposite with well controlled healing process and improved mechanical durability, basedon the protocols published by other groups and the methods developed by ourselves. With thehelp of material development, we will be able to perform systematic study on the interactionbetween microorganisms and the slippery surfaces under mechanical disturbances. The proposedproject would not only advance our understanding on developing self-healable slippery materials,but also give new insight to the design of anti-fouling materials which will benefit theapplication of fouling resistant biomedical devices and many other biomedical applications.
