One-Pot, Bioinspired Coatings To Reduce the Flammability of Flexible Polyurethane Foams

In this manuscript, natural materials were combined into a single “pot” to produce flexible, highly fire resistant, and bioinspired coatings on flexible polyurethane foam (PUF). In one step, PUF was coated with a fire protective layer constructed of a polysaccharide binder (starch or agar), a boron fire retardant (boric acid or derivative), and a...

Biobased Polyurethanes Prepared from Different Vegetable Oils

In this study, a series of biobased polyols were prepared from olive, canola, grape seed, linseed, and castor oil using a novel, solvent/catalyst-free synthetic method. The biobased triglyceride oils were first oxidized into epoxidized vegetable oils with formic acid and hydrogen peroxide, followed by ring-opening reaction with castor oil fatty...

This study for the first time reports the unusual sorption capabilities of polyurethane foam (PUF) for bisphenol A (BPA) - a major industrial plasticizer and endocrine-disrupting chemical ubiquitously detected in environmental waters. The low surface-area material showed not only anomalously high sorption capacities, but also rapid uptake for BPA...
