Polymer membranes for gas separation prepared using green solvent

Popis výsledku v původním jazyce

Although, the polymer membranes are advantageous tools for gas separation, one of the disadvantages increasingly important to investigate is the toxicity of common solvents. Generally used solvents such as dimethylformamide (DMF), dimethylacetamide (DMAc), or N-Methyl-2-pyrrolidone (NMP), exhibit significant toxicity. NMP), exhibit significant toxicity. Many research studies have confirmed the environment toxic effect, including impacts on human health such as endocrine or immune system disruption, brain damages, reproductive disabilities, fetal development inhibitions or it can trigger cancer. Moreover, they can have harmful effect after long-term exposure, for example in a manufacturing work environment.Therefore, there is growing demand for the use of green solvents in membrane separation. In our study we examined the use of low-hazard solvent 1,3-dimethyl-2-imidazolidinone (DMI) for the creation of polysulfone (PSU) membrane designed for gas separation. DMI is water soluble substance used as a pharmaceutical additive and in persona! care products. PSU is commonly used polymer in many sectors in industry as well as in gas separation applications. This thermoplastic polymer has suitable mechanical properties, thermal properties and chemical stability as resistance to acid or base environments. Exanimated polymer membranes were fabricated via Doctor hlade method. Structural properties of successfully prepared polymer films were investigated via AFM, SEM, DSC, GPC and also, they were proveď for mechanical properties as Young&apos;s modulus. Additionally, membrane&apos;s gas permeability was measured for various of gases such as CO2, N2 or 02.
