Durable hydrophobic coatings are created by adding amphiphilic Janus particles to binder polymers through the unique self-stratification behaviours, which offer a novel and cost-effective solution to challenges in waterborne emulsion coatings.

This review outlines the progress in biobased foams with a focus on low thermal conductivity. It introduces materials selection and processing, compares performance, examines modelling of physical properties, and discusses challenges in applying models to real systems.
