abstract This study reports on the development of nanocomposite foams, prepared by Pickering emulsion templating, with promising tailored-properties, simply tunable by their composition. The selected multi component monomer mixtures comprise acrylated epoxidized soybean oil (AESO), 1,6-hexanediol diacrylate (HDD) and divinylbenzene (DVB), chosen by their renewable-origin or resemblance to renewable ones, and above all due to their varying stiffness or crosslinking-ability. The Pickering water in -oil emulsions, after their fast stabilization using cyclohexane and acetylated bacterial cellulose, were used as templates for the polymeric foams production. These original materials were thermally stable up to approximately 320 degrees C, and had a Young's modulus varying between 3.41 and 1639 MPa, being the highest results prompted by the use of HDD or DVB.
