Special Issue Information

Dear Colleagues,

Polymer films play a vital role in a broad range of technologies where surface functionality is essential, including protective coatings, packaging, biomedical devices, filtration systems, and energy applications. Recent advances in polymer chemistry and deposition techniques have enabled the fabrication of polymer thin films with highly tunable surface properties such as wettability, adhesion, optical transparency, and chemical or biological responsiveness.

This Special Issue aims to highlight recent advances in the design, fabrication, and application of functional polymer films developed via both vapor-based (e.g., chemical vapor deposition, plasma polymerization) and solution-based (e.g., spin-coating, dip-coating, layer-by-layer assembly, sol–gel processing) techniques.

We welcome contributions focusing on polymer films engineered for the following:

  • Controlled surface wettability (hydrophobic, hydrophilic);
  • Advanced surface functionalities;
  • Conductive, dielectric, or semiconducting behavior;
  • Stimuli-responsive or environmentally adaptive surfaces;
  • Surface patterning, texturing, or hierarchical structuring;
  • Theoretical modeling or simulation of surface-related phenomena.

Both experimental and theoretical studies are encouraged, ranging from fundamental investigations to application-oriented research with potential for real-world impact.

We invite researchers from across disciplines, including polymer science, materials chemistry, surface engineering, and nanotechnology, to contribute their latest findings. Your work will contribute to a deeper understanding of how polymer films can be tailored for advanced surface modification and coating applications.

Polydimethylsiloxane (PDMS) is widely used in microfluidics and medical devices; however, its inherent hydrophobicity limits its applications. This can be resolved by the formation of polyethylene glycol (PEG)-based hydrophilic coatings. Here, we aimed to prove that PDMS surfaces modified with low molecular weight PEG (400) provided a more stable hydrophilic surface. The lowest contact angle achieved via using PEG400 and the “grafting from” approach was 8.6 ± 3.5°. Under perfusion conditions, imitating arterial and capillary flows, such coatings were considerably stable, and the contact angle was kept at 45.5° after 3 days. Moreover, the applied surface modifications preserved surface roughness, elastic modulus, and optical transparency. Thus, these findings confirmed that the “grafting from” approach with low molecular weight PEG could be the most effective strategy to form hydrophilic PDMS coatings with optimal performance in biomedical applications.
