ABSTRACT
This talk covers the recent development in two important areas which are soft fibrillar materials and functional particles. Soft fibrillar materials have important applications in many fields such as tissue engineering and functional foods. The fiber network structure determines the mechanical properties and application performance of these materials. In this context, significant efforts have been devoted to the production of soft materials with desirable fiber structures. However, chemical approaches have been generally applied, which are laborious with low efficiency. In this presentation, novel strategies developed to engineer fiber networks on the basis of the nucleation and crystallization mechanism of fiber formation will be discussed. These physical strategies make it convenient to tune the fiber network structures in soft materials by simply manipulating the thermodynamic driving force and kinetics of fiber nucleation. Fibrillar materials made of small molecular gelators and natural silk proteins will be used to illustrate the strategies. In addition，the applications of functional particles in two new areas which are photothermal cancer treatment and protective coating (for corrosion inhibition) will also be presented.  Critical factors governing the applications of particles in these fields will be analysed.
