報告内容簡介：
The intermolecular interactions and surface characteristics of materials significantly determine their physicochemical properties and functionalities. Much effort has been devoted to characterizing the intermolecular and surface interactions (e.g., adhesion), especially noncovalent interactions, in soft materials (e.g., surfactants, polymers, biopolymers) and biological systems. In this talk, the basics of intermolecular and surface forces and some commonly used nanomechanical techniques will be briefly introduced. The recent progress on how we applied nanomechanical tools for quantifying the intermolecular and surface interactions of polymer/biopolymer materials and biological systems (e.g., wet adhesion of marine mussels) will be presented. Our recent studies have systematically characterized the intermolecular and surface interaction mechanisms of mussel adhesives. The fundamental interaction mechanisms elucidated (e.g., biopolymer-metal ion coordination, cation-π, anion-π, hydrophobic and hydrogen bonding interactions in aqueous media) have been further applied for developing multifunctional soft materials (e.g., self-healing polymers/hydrogels, wet adhesives) with various bioengineering applications. These findings provide useful insights into biological self-assembly processes and new approaches to develop multifunctional soft materials or surfaces via tunable noncovalent interactions.
