Transparent Nanocellular Polymers In A One-Step Process: Key Factors Affecting Transmittance

Abstract: This work presents the production of transparent nanocellular materials with 61 % of transmittance in a production time of 2.5 hours with no post-processing needed. The key parameters to obtain those results are the use of high saturation pressures, 40 and 50 MPa combined with a saturation temperature of 0 ºC, and foaming temperatures between 25 and 60 ºC. The produced cellular materials have been in deep study, and the influence of the cellular structure, solid skin and transition region on the final transmittance have been determined.

Biography: Judith Martin de León is a Doctor in Physics from the University of Valladolid since 2019. She finished her degree in Physics at the University of Valladolid in 2014. Afterward, she performed a two-year Interuniversity Master's degree: "Master in Molecular Nanotechnology and Nanoscience."

She has been in contact with polymer science since 2012, thanks to her first collaboration with CellMat Laboratory from the University of Valladolid. In particular, her research has been focused on Nanocellular Polymers. She started this study as a part of her Master's. Later, she performed her thesis in Nanonocellular Polymers based on PMMA driven by homogeneous nucleation in CellMat Laboratory and directed by Miguel Ángel Rodriguez Pérez. With more than 20 papers on this topic and 34 participations in national and international congress, she is part of the group of experts in nanocellular polymers of the CellMat Laboratory. CellMat Laboratory is one of the pioneers and most international valued laboratories in the nanocellular polymers field, presenting the first transparent nanocellular polymer, part of the thesis of the young researcher, among other significant findings.

Actually, she is still working in the nanocellular polymers field as a part of CellMat Technologies S.L. She is also a Teaching Fellow at the University of Valladolid.
