Room-temperature autonomous self-healing glassy polymers with hyperbranched structure

Room-Temperature Polydimethylsiloxane-Based Self-Healing Polymers

Polymers that respond in a productive fashion to their environment are under active development as they offer significant advantages over traditional materials. For example, polymers with the ability to self-heal and recover a significant fraction of their initial properties after being subjected to a damage event are of significant interest. Here we study the effect of healing agent viscosity ...

Self-healing hyperbranched poly(aroyltriazole)s

Self-healing Polymers

These images present the dramatic reduction in corrosion of a steel plate coated with a self-healing coating (right) as compared to a conventional coating. Both samples were scratched and placed in 5% NaCl for 5 days. The background is an optical image (2x magnifi cation), in the foreground is an SEM image of the scratch. In the self-healing sample, the scratch has almost completely self-healed...

Self-healing Polymers

Self-healing polymers are a new class of smart materials that have the capability to repair themselves when they are damaged without the need for detection or repair by manual intervention of any kind. Increasing demand for petroleum feed stocks used to produce polymer and the need for polymeric materials with improved performance in challenging applications continue to drive the need for mater...

Membrane Functionalization with Hyperbranched Polymers

Polymer membranes have been modified with hyperbranched polymers with the aim to generate a high density of hydrophilic functional groups at the membrane surface. For this purpose hyperbranched polymers containing amino, alcohol, and carboxylic acid end groups were used for membrane modification, respectively. Thus, surface potential and charges were changed significantly to result in attractiv...
