Popis: International audience; New formulations of procyanidin tannin-based foams have been developed for the first time with maritime pine (Pinus pinaster) tannins. These tannins have an extremely high reactivity which makes them difficult to use for traditional tannin-based foams. For this work, an equipment named FOAMAT was used to record simultaneously temperature, pressure, velocity and dielectric polarization during foaming. The results highlight the role of surfactant (castor oil ethoxylate) and plasticizer (Polyethylene glycol) during foam formation: polymerization, expansion, hardening, and shrinkage. In this work, foams density - and its physical properties are either surfactant or plasticizer-controlled. With polyethylene glycol and castor oil ethoxylate, homogeneous microstructure foams were obtained but polyethylene glycol made the foams more elastic and improved their shrinkage.
