Ultrasonic treatment reduces pore size and enhances compressive strength and elasticity in methyl methacrylate monoliths, suggesting improved material performance.
Key Points
This research examines the impact of sonication on the characteristics of methyl methacrylate-based PolyHIPE monoliths.
Prepared high internal phase emulsions (HIPEs) using methyl methacrylate and ethylene glycol dimethacrylate.
Emulsions underwent ultrasonic treatment prior to photopolymerisation.
Analyzed morphology and mechanical properties through pore diameter assessment and compression testing.
Sonication reduced average pore size by 10% to 50%.
Improved pore uniformity correlated with higher compressive strength compared to non-sonicated samples.
Elasticity of the materials increased following ultrasonic treatment.
