The response of switchable polymer blends and coatings to temperature variation is important for the development high-performance materials. Although this has been well studied bulk materials, a proper understanding at molecular level, in particular high stretching forces, still lacking. Here we investigate details temperature-dependent elastic two widely used water-soluble polymers, namely, polyethylene glycol (PEG) poly(N-isopropylacrylamide) (PNiPAM) with combined approach using atomic...
Abstract Lignin is an abundant polymer found in wood and grasses, but due to its heterogeneity complex macromolecular structure it has been less utilized than cellulose. While the building blocks are known, way they linked understood. Here, Molecular Dynamics simulations were used systematically characterize seven linkages native lignin. Their influence on lignin water structure, their interactions analyzed. The study limited guaiacyl (G-G) dimers connected by following common softwood...
Abstract Softwood branches develop compression wood (CW) in the lower parts of branch, while opposite (OW) develops on upper. These types differ structure at several length scales, among others chemical composition their lignin matrix. While OW mostly contains guaiacyl (G) units, CW is known to contain a substantial fraction 4-hydroxyphenyl (H) lignin. In this study, impact difference has hygroexpansion and interaction with water studied by means atomistic models molecular dynamics computer...
