Abstract Surface functionalization technologies of fibrous or porous materials are often considered relatively unstable with a shelf life several weeks months at most, evoked by heterogeneous treatment their internal surface areas. Here, it is demonstrating that the fine balance plasma etching, deposition, and oxidation involving different reactive species, strongly enhances penetration depth within complex structures. On this basis, capillary wicking maintained over >10 years after...
Hexamethyldisiloxane (HMDSO) low-pressure plasmas are known for their versatility in the deposition of plasma polymer films (PPFs) with different properties and applications. Although they have been studied decades, reaction mechanisms formation leave open questions, particularly when on 3D materials complex geometries such as cavities undercuts is considered. In present study, two configurations named "cavity" "undercut" selected to study influence diffusion film-forming species surface...
Excellent adhesion of electrospun nanofiber (NF) to textile support is crucial for a broad range their bioapplications, e.g., wound dressing development. We compared the effect several low- and atmospheric pressure plasma modifications on between two parts composite-polycaprolactone (PCL) nanofibrous mat (functional part) polypropylene (PP) spunbond fabric (support). The fabrics were modified before electrospinning by low-pressure oxygen treatment or amine polymer thin film treated slit jet...
Abstract Plasma polymers (PPs) can easily modify material surfaces to improve their bio‐applicability due match‐made surface‐free energy and functionality. However, cell adhesion PPs typically composed of various functional groups has not yet been fully understood. We explain the origin strong resistance trypsin treatment previously noted for nonendothelial cells on amine PPs. It is caused mainly by nonspecific negatively charged parts transmembrane proteins positively PP surface, enabled...
