“…Different surface modifications of polypropylene nonwoven fabric (NWF) by using mineral particles are proposed to increase fabric hydrophilicity 4 . In Verma et al's study, 5 antimicrobial polypropylene was obtained by plasma functionalization and subsequent immobilization of chitosan‐chlorhexidine nanogels as a bioactive component.…”

Polytetrafluoroethylene (PTFE), octenidine dihydrochloride (OCT), and zinc oxide (ZnO) were used to modify the polypropylene nonwoven material by the methods of “wet chemistry” and low‐energy electron beam deposition (EBD). The influence of nonwoven material modification on the morphology, chemical composition, filtration, and antibacterial properties was established. The modified material has antibacterial activity against the gram‐positive strain Staphylococcus aureus and against gram‐negative strains of Escherichia coli and Klebsiella pneumoniae (suppression of bacterial growth for materials with OCT was 100%, with ZnO—70%). PTFE application to Aquaspun leads to a significant increase in the contact angle (from 141.3° to 152.7°) and air filtration efficiency (from 78.3% to 83.4%), which provides the barrier properties of the material. It was established that the material obtained using low‐energy EBD demonstrated a more pronounced antimicrobial potential against the tested strains of St. aureus.Highlights The influence of polypropylene nonwoven materials surface modification methods is systematically investigated. Low‐energy electron beam deposition increases antibacterial and filtration properties of nonwoven materials. Surface modification methods increase barrier properties of polypropylene nonwoven materials.

Polypropylene (PP) is an unflinching element of biomaterials for human healthcare, leading to enormous possibilities for their functional development within a broad range of biocompatible and bioreceptive materials. Plasma grafting of itaconic acid was carried out on a PP surface by oxygen plasma activation. The variation of grafting parameters, such as monomer concentration, reaction temperature and reaction time, as a function of the degree of grafting was investigated. The graft distribution and surface homogeneity of the PP surfaces were evaluated using confocal microscopy, field emission scanning electron microscopy and atomic force microscopy. These surface characterizations led to information about the impact of grafts on the material surface. © 2023 Society of Industrial Chemistry.

Polyurethane (PU) has a diverse array of customized physical, chemical, mechanical, and structural characteristics, rendering it a superb option for biomedical applications. The current study involves modifying the polyurethane surface by the process of aminolysis (aminolyzed polyurethane; PU‐A), followed by covalently immobilizing Carboxymethyl cellulose (CMC) polymer utilizing Schiff base chemistry. Oxidation of CMC periodically leads to the creation of dialdehyde groups along the CMC chain. When the aldehyde groups on the OCMC contact the amine group on a modified PU surface, they form an imine bond. Scanning electron microscopy (SEM), contact angle, and X‐ray photoelectron spectroscopy (XPS) techniques are employed to analyze and confirm the immobilization of OCMC on aminolyzed PU film (PU‐O). The OCMC gel incorporates Nitrofurantoin (NF) and immobilizes it on the PU surface (PU‐ON), creating an antibacterial PU surface. The confirmation of medication incorporation is achieved using EDX analysis. The varying doses of NF have demonstrated concentration‐dependent bacteriostatic and bactericidal effects on both Gram‐positive and Gram‐negative bacteria, in addition to sustained release. The proposed polyurethane (PU‐ON) surface exhibited excellent infection resistance in in vivo testing. The material exhibited biocompatibility and is well‐suited for biomedical applications.
