Fully biobased and biodegradable materials have attracted a growing interest in the food packaging sector as they can help to reduce negative impact of fossil-based plastics on environment. Moreover, addition functionalities these by introducing active molecules has become an essential requirement create modern able extend food's shelf-life while informing consumer about quality freshness. In this study, we present innovative bioplastic formulation for based poly(hydroxybutyrate-co-valerate)...
The gas separation performance of biopolymers is still scarcely characterized, mostly because their poor thermomechanical properties and high crystallinity which associated to low permeability. In this work we characterize the transport in a poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) random copolymer, that has relatively good mechanical properties, combined with renewable origin, biodegradability biocompatibility. study also compared several solvents for membrane casting, different...
The outbreak of SARS-CoV-2 pandemic highlighted the worldwide lack surgical masks and personal protective equipment, which represent main defense available against respiratory diseases as COVID-19. At time, shortage was dramatic in Italy, first European country seriously hit by pandemic: aiming to address emergency support Italian industrial reconversion production masks, a multidisciplinary team University Bologna organized laboratory test according regulations. group, driven expertise...
The transport of H2, He, CO2, O2, CH4, and N2 at three temperatures up to 65 °C was measured in dense, thick composite films formed by amorphous Polysulfone (PSf) particles the size-selective zeolitic imidazolate framework 8 (ZIF-8) loadings 16 wt%. morphological structural properties membranes were analyzed via SEM density measurement. addition ZIF-8 PSf enhances H2 He permeabilities 480% with respect pure polymer, while ideal H2/CO2 He/CO2 selectivities MMMs reach values 30–40% higher than...
In this work, we assessed the CO2 and CH4 sorption transport in copolymers of 3-hydroxybutyrate 3-hydroxyvalerate (PHBV), which showed good capture potential our previous papers, thanks to their solubility–selectivity, are biodegradable alternatives standard membrane-separation materials. Experimental tests were carried out on a commercial material containing 8% (HV), while molecular modelling was used screen performance across entire composition range by simulating structures with 0%, 8%,...
The majority of materials used for membrane-based separation gas mixtures are non-renewable and non-biodegradable, the assessment alternative bio-based polymers requires expensive time-consuming experimental campaigns. This effort can be reduced by adopting suitable modelling approaches. In this series works, we propose various approaches to assess CO2/CH4 performance eight different copolymers 3-hydroxybutyrate 3-hydroxyvalerate (PHBV) using a limited amount data model calibration. part 1,...
Torlon® is a thermally and plasticization-resistant polyamide imide characterized by low gas permeability at room temperature. In this work, we aimed improving the polymer performance in thermally-enhanced He/CO2 H2/CO2 separations, compounding with highly permeable filler, ZIF-8, to fabricate Mixed Matrix Membranes (MMMs). The effect of filler loading, size, temperature on MMMs permeability, diffusivity, selectivity was investigated. He increased factor 3, while decreased 2, when adding 25...
