Overview

In vitro study demonstrates dual antibacterial and anti-adhesion capabilities in soft PVC composites, highlighting a viable molecular strategy for safer medical devices.

Key Points

To synthesize novel multifunctional hyperbranched polymeric additives via atom transfer radical polymerization to impart both contact-killing and anti-adhesion antifouling capabilities to soft medical PVC.
Synthesized hyperbranched poly(ethyleneimine)-poly(ε-caprolactone) (PEI-PCL) cores and grafted PEGMA and/or DMAEMA chains using atom transfer radical polymerization (ATRP).
Quaternized tertiary amine groups to produce cationic variants (PEI-PCLQ and dual-functional PEI-PCLQE) and blended them into soft PVC.
Evaluated structural properties, thermal transitions, bactericidal efficiency, biofilm inhibition, platelet activation, and hemocompatibility.
Quaternary ammonium functionalization induced an amorphous structural transition in the additive, delivering > 90% bactericidal efficiency in PVC composites.
Grafting PEGMA preserved semi-crystallinity and imparted robust anti-adhesion properties, significantly suppressing bacterial adhesion and biofilm formation.
The dual-functional PEI-PCLQE additive attenuated platelet activation and achieved excellent hemocompatibility with a hemolysis rate < 2%.
