报告摘要:
The intermolecular interactions and surface characteristics of materials play a crucial role in determining their physicochemical properties and functionalities. Extensive efforts have been devoted to characterizing these interactions, particularly noncovalent ones, in soft materials (e.g., surfactants, polymers, biopolymers) and biological systems. In this talk, I will briefly introduce the basics of intermolecular and surface forces, along with some commonly used nanomechanical techniques. I will also present recent progress on how we have applied nanomechanical tools to quantify the intermolecular and surface interactions in polymer/biopolymer materials and biological systems, such as the wet adhesion of marine mussels. Our recent studies have systematically characterized the intermolecular and surface interaction mechanisms in mussel adhesives. The fundamental mechanisms elucidated, including biopolymer-metal ion coordination, cation-π, anion-π, hydrophobic, and hydrogen bonding interactions in aqueous media, have been further applied to the development of multifunctional soft materials, such as self-healing polymers/hydrogels and wet adhesives, with various bioengineering applications. These findings offer valuable insights into biological self-assembly processes and suggest new approaches to developing multifunctional soft materials and surfaces via tunable noncovalent interactions.
