The research article 'The Synthesis of Fiber Membranes from High-Impact Polystyrene (HIPS) Waste using Needleless Electrospinning as Air Filtration Media' has been published in Elsevier journal Materials Today: Proceedings (Volume 13, Part 1, 2019, Pages 154-159).

Abstract

The production and characterization of air filter membranes from HIPS waste are presented. The HIPS membranes were synthesized using needleless electrospinning. The HIPS precursor solutions were made by dissolving the HIPS waste in the d-limonene:DMF solvent mixing ratio of 3:1, 1:1, and 1:3. The different mixing ratio led to different viscosity, surface tension, and fiber morphology. Beaded to fine fiber morphology were obtained by increasing the DMF concentration in the mixing solvent. The filtration test using PM2.5 as test particles demonstrated the good performance of the HIPS membrane as an air filter media (filtration efficiency up to 98.75%).
