20.500.12556/RUL-158295 Influence of porosity and microstructure on compression behavior of methacrylate polymers in flow-through applications Mechanical properties of a material play a pivotal role in its performance when such porous material is used in a flow-through mode. This study delves into the effect of porosity and microstructure on the compressibility of methacrylate polymer, focusing on two distinct microstructures: cauliflower and high internal phase emulsion. Samples with various porosities yet identical chemical composition were prepared and their Young’s modulus was measured. The effect of porosity on Young’s modulus was described by an exponential law model with the cauliflower microstructure exhibiting an exponent of 3.61, while the high internal phase emulsion of only 1.86. A mathematical analysis of the compression caused by a liquid flow unveiled significant disparities in the porosity threshold where minimal compression is observed, being around 0.45 for the cauliflower while there is monotone decrease in compression with porosity increase for the high internal phase emulsion microstructure. Evaluating exponent integer values between 1 and 5 over entire porosity range reveals that the porosity where the minimal compression occurs increases with a decrease in exponent value, being approximately 0.33 for n = 5, 0.4 for n = 4, 0.55 for n = 3, 0.65 for n = 2 while no minimum occurs for n = 1. These findings indicate that lower exponent value results in lower compression under identical experimental conditions. compression mechanical properties microstructure porosity Young's modulus kompresija mehanske lastnosti mikrostruktura poroznost Youngov modul true false true Angleški jezik Slovenski jezik Članek v reviji 2024-06-03 09:56:27 2024-06-03 09:56:28 2024-06-15 03:47:24 0000-00-00 00:00:00 2024 0 0 11 str. iss. 9/10, art. 2300767 Vol. 47 May 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.1 1615-9314 10.1002/jssc.202300767 197425411 J_of_Separation_Science_-_2024_-_Poljanec_-_Influence_of_porosity_and_microstructure_on_compression_behavior_of.pdf J_of_Separation_Science_-_2024_-_Poljanec_-_Influence_of_porosity_and_microstructure_on_compression_behavior_of.pdf 1 EB96C1CBF9B38F28499EE23A9567C964 00876eee235b06c1f124d3cd4d886dca0ab89486cfc40e52901001c6e5181ceb ff5bd93c-217e-11ef-babb-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=185833 https://analyticalsciencejournals.onlinelibrary.wiley.com/doi/10.1002/jssc.202300767 1 c82dd3cf-217e-11ef-babb-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=185832 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
