Mussel‐Inspired Polyglycerol Coatings for Surface Modification with Tunable Architecture

Mussel-inspired coatings, known for their outstanding substrate-independent adhesive capabilities, have numerous potential applications in materials science and biomedical fields. To improve the understanding of how these polymers’ molecular structure chemical composition affect coating mechanisms resulting properties, herein three mussel-inspired polymers are developed: dendritic polyglycerol with 40% catechol groups 60% amines (dPG40), linear 80% catechols 20% (lPG80), finally lPG40 amines. After a series characterizations, it is found that surface modification monolayer can be easily achieved lPG40, robust well-defined nano- to micro-structural coatings possible lPG80 dPG40. Tunable properties include not only speed, but thickness, roughness, surficial topography. This diverse suite controllable attributes enables (MiPG) satisfy wide-range on multiple materials.
