PEDOT:PSS—A Key Material for Bioelectronics

open access: yesAdvanced Science, Volume 13, Issue 11, 23 February 2026.
PEDOT:PSS ‐ Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate ‐ is typically processed from water dispersions to form multifunctional and multidimensional constructs with tunable electronic and ionic conductivity. Throught processing engineering, PEDOT:PSS is intergrated in bioelectronic devices that operate efficiently in physiological conditions

Functionalized Polyolefin With Photoresponsive Surface

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
The introduction of stimulus‐responsive groups can give polymers some material properties that cannot be realized simply by design and synthesis. Polyolefins, due to their nonpolar nature, suffer from poor compatibility with polar materials; however, directly grafting polar groups like hydroxyls onto their surface via traditional synthesis risks ...

Developing Calibration Reference Materials and Standardized Protocols for Reliable DSC of Polyolefins

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 3, January 15, 2026.
Standardized protocol for reducing T m standard deviation. ABSTRACT Differential scanning calorimetry (DSC) serves as a critical analytical tool in the polyolefin industry for quality control and product differentiation. Between 2000 and 2025, 7574 global patent applications referenced DSC data, highlighting its ubiquitous role in the industry.

Deciphering the Role of Internal Donors in Shaping Heterogeneous Ziegler-Natta Catalysts Based on Non-Empirical Structural Determination

open access: yes, 2023
The addition of internal donors (IDs) to the heterogeneous Ziegler-Natta catalyst for propylene polymerization is fundamental to obtain highly isotactic polypropylene, but its role in shaping the stereospecific structure of the catalyst is still not ...
