Adhesion of Mucilage Plant Seed: A molecular simulation approach

Our research aims to predict and understand the properties of soft materials, especially polymer solutions and liquid droplets, using multiscale computational techniques. Certain polymers, such as pectin, can form gel-like structures upon hydration, which enhances their adhesive properties. Experimental evidence shows that when water is removed from the polymer network within seed mucilage, it creates a potential adhesive bond between the seed and nearby surfaces. This project focuses on developing a coarse-grained model based on pectin oligosaccharide chemistry to replicate its mechanical properties. Interaction parameters for liquids, polymers, and surfaces are derived from their physical characteristics, including interfacial tension, compressibility, and wetting properties. The study will also examine how varying desiccation time affects the adhesive strength of pectin, providing insight into the mechanics of pectin solution adhesion on flat hydrophilic surfaces.
