High Internal Phase Emulsion (HIPE) foam having cellulose nanoparticles is disclosed. The HIPE is formed by polymerizing a High Internal Phase Emulsion comprising: a) an oil phase comprising i) monomer; ii) cross-linking agent; iii) emulsifier; iv) cellulose nanoparticles; and b) an aqueous phase. The High Internal Phase Emulsion foam may exhibit a compression modulus of between 20 KPa and 200 KPa. The cellulose nanoparticles may be present in an amount between about 0.001% and 5% by weight of the oil phase. The cellulose nanoparticles may be Microfibrillated cellulose (MFC), Microcrystalline cellulose (MCC), Nanocrystalline cellulose (NCC), Nano cellulose or Nanocellulose or Bacterial nanocellulose, Nanofibrillated cellulose (NFC), Cellulose nanofiber(s), Cellulose microfibril or cellulosic microfibril(s), Cellulose nanorod or cellulosic nanorod(s), Cellulose nanocrystal(s) (CNC), or combinations thereof. The aqueous phase may comprise an initiator. |
