Aging in polymers of intrinsic microporosity has slowed exploitation due to a decay in performance over time since densification makes them unsuitable for industrial applications. This work aimed to study the impact of the operation and storage tempe

An optimized Friedel-Crafts based methodology used to prepare high surface area and pore volume hyper-cross-linked polymers (HCPs) is presented here. A significant reduction in catalyst quantities resulted in an HCP showing SSABET of 905 m2/g and tot

Mixed Matrix Membranes based on PPO and graphene for gas separation

Autor: Riccardo Rea, Maria Grazia de Angelis, Simone Ligi, Marco Giacinti Baschetti

Novel composite Mixed Matrix Membranes (MMM) were fabricated by dispersion of different loadings of graphene nanoparticles (from 0.3 to 15 % weight percentage) in a dense permeable glassy polymer, poly (2,6-dimethyl-1,4-phenylene oxide), PPO, by solv

Reactive absorption of CO2 and H2S in aqueous methyldiethanolamine (MDEA) solutions is considered within the ePC-SAFT equation of state. We demonstrate that ePC-SAFT can be employed in a predictive manner without regression of additional temperature-
