AI Article Synopsis
- Miniaturizing and controlling materials at the nanoscale is essential in nanoscience and nanotechnology, especially for creating ultra-thin polymer films with uniform thickness.
- By utilizing a custom-designed polymer and precise nanofabrication techniques, researchers produced defect-free membranes with high carbon dioxide permeance, exceeding 5 m³ (STP) m⁻² h⁻¹ bar⁻¹.
- These ultra-thin membranes, being only a few tens of nanometers thick and made from CO₂-philic materials, have significant potential for applications like separating carbon dioxide from flue gas in large-scale gas treatment.
Article Abstract
Miniaturization and manipulation of materials at nanometer scale are key challenges in nanoscience and nanotechnology. In membrane science and technology, the fabrication of ultra-thin polymer films (defect-free) on square meter scale with uniform thickness (<100 nm) is crucial. By using a tailor-made polymer and by controlling the nanofabrication conditions, we developed and manufactured defect-free ultra-thin film membranes with unmatched carbon dioxide permeances, i.e. > 5 m(3) (STP) m(-2) h(-1) bar(-1). The permeances are extremely high, because the membranes are made from a CO(2) philic polymer material and they are only a few tens of nanometers thin. Thus, these thin film membranes have potential application in the treatment of large gas streams under low pressure like, e.g., carbon dioxide separation from flue gas.

African swine fever (ASF) is an acute hemorrhagic disease in pigs caused by the African swine fever virus (ASFV), which has a high mortality rate and brought great damage to global pig farming industry. At present, there is no effective treatment or vaccine to combat ASFV infection, so early detection of ASFV has become particularly important. Therefore, the PDMS/chitosan/MPMs composite film was proposed to detect ASFV P72.

A mechanically robust flexible transparent conductor with high thermal and chemical stability was fabricated from welded silver nanowire networks (w-Ag-NWs) sandwiched between multilayer graphene (MLG) and polyimide (PI) films. By modifying the gas flow dynamics and surface chemistry of the Cu surface during graphene growth, a highly crystalline and uniform MLG film was obtained on the Cu foil, which was then directly coated on the Ag-NW networks to serve as a barrier material. It was found that the highly crystalline layers in the MLG film compensate for structural defects, thus forming a perfect barrier film to shield Ag NWs from oxidation and sulfurization.
