Webb11 apr. 2024 · Vegetable oils or fats are one of the most important renewable resources and mainly consist of triglyceride esters with different fatty acid chains. These components contain a number of highly functional sites in the form of unsaturated -C = C- bonds, triglyceride ester groups, and allylic reactive positions. Therefore, they present a … Webb9 apr. 2024 · The fabrication process contains four main steps: i) Preparing homogenous mixtures containing monomers, porogens, and a photoinitiator; ii) The cross-linking of monomers is initiated by UV irradiation, leading to the phase separation of the porogens and the cured polymer; iii) Extracting porogens by submerging the as-prepared polymer …
