Low-density PDMS foams by controlled destabilization of thixotropic emulsions

Low-density PDMS foams by controlled destabilization of thixotropic emulsions

In the current study we demonstrate a method of preparation of low-density polydimethylsiloxane (PDMS) foams from emulsions by using water-based thixotropic fluids as porogens. Aqueous dispersions of synthetic hectorite clay and nanocellulose were used as thixotropic fluids, enabling the preparation...
