Advanced and Sustainable Manufacturing Methods of Polymer-based Membranes for Gas Separation: A Review

Research output: Contribution to journalReview articlepeer-review

Abstract

The fabrication of membranes for gas separation presents challenges that hinder
their deployment as a truly sustainable technology. This review systematically
explores the evolution and advancements in materials and manufacturing
methods of polymer-based membranes, with a keen emphasis on
sustainability and efficiency. The review delineates a broad spectrum of
manufacturing techniques, ranging from traditional methods to cutting-edge
approaches such as layer-by-layer assembly, and green synthesis, highlighting
their implications for environmental sustainability, performance enhancement,
scalability, and economic viability. Key findings indicate a significant shift towards
greener solvents, bio-based polymers and processes that reduce waste and
costs. Critical analysis uncovers a growing focus on understanding the life
cycle of membranes and developing strategies for end-of-life such as
recycling and the use of biodegradable materials, underscoring the
commitment of the community to minimizing environmental footprints.
