AI Insight
Researchers discovered that complete, interconnected networks in polymer membranes enable precise molecular transport pathways at the angstrom scale (one ten-billionth of a meter). The study demonstrates that network completeness—where transport channels form fully connected pathways throughout the material—is critical for controlling how molecules move through these membranes. This finding provides fundamental insight into designing membranes with highly selective molecular separation capabilities.
Why it matters
This discovery could improve technologies for water purification, chemical separation, and gas filtration by enabling the design of membranes that more precisely control which molecules pass through. Better membrane selectivity could reduce energy costs in industrial separation processes and improve efficiency in applications ranging from desalination to pharmaceutical manufacturing.
