“…Specifically, polyolefin represents a highly versatile biomaterial that has been extensively studied and used in clinical practice. , Significant success has been demonstrated for polyolefins in a wide range of biomedical applications, with more than 700 FDA-approved medical devices utilizing this class of material. For medical applications, polyolefins with antimicrobial properties are highly desired. , The most common strategy to access such materials is direct mixing of antimicrobial agents with polyolefins through blending or coating. , However, the nonpolar nature of polyolefins make them noncompatible with these antimicrobial agents, thus limiting their properties and applications. , For example, it has been shown that silver nanoparticles in polyethylene composites can migrate from the packaging to the content . Recently, polar functional groups bearing antimicrobial capabilities can be grafted onto polyolefin through the reactive extrusion process .…”

Polyolefins with antimicrobial properties are generally prepared through blending or coating with antimicrobial agents. However, the nonpolar nature of polyolefins brings many issues including the difficulties in homogeneous mixing. In this contribution, we report the synthesis of polyolefins with intrinsic antimicrobial properties through three different routes. First, direct copolymerization of ethylene with nitrogen-containing comonomers affords some nitrogenfunctionalized polyolefins with moderate antimicrobial properties. Subsequently, two postpolymerization functionalization routes enable the formation of imidazolium and various metal ion-functionalized polyolefins through the conversion of preinstalled chlorine and carboxylic-functional groups. In addition to high molecular weight and high functional group incorporation, these alternative routes generate polyolefins with excellent mechanical and antimicrobial properties. This work demonstrates the importance of different functional groups in determining the antimicrobial properties of polyolefin materials.

“…Due to the nature of fabrics structures including a large surface area and the ability to retain moisture, they are more exposed to bacterial activities, causing a range of undesirable effects on both the textile itself and on the user [22]. Thus, a variety of fabric treatment methods have been developed for applying antimicrobial coatings, including pad-dry-cure, conventional exhaustion, padding, spraying, polymer grafting of active agent during polymerization, encapsulation of metal NPs by in-situ formation of some heavy metals NPs in polymer surfaces and chemical modification with active agents by binding with polymer surfaces covalently [34]. The latter method involves the use of graft copolymerization to alter properties of polymer substrate surfaces to meet specific applications.…”

“…The selection of the substrates and biocidal agent for antimicrobial treatment depends on the desired applications [63]. Processed polymers/polymer composites in forms of fibers, cannulas, catheters, nonwoven fabrics, nanofibers, films, and membranes without and with NPs (schematized in Figure 5) have been subjected to surface antimicrobial treatments [34,64,65]. In this case, antimicrobial agents are coated to substrates physically (dip-coating, spray coating, spin coating, solvent casting, or layer-by-layer) or chemically/covalently (graft copolymerized) where only their surface properties are selectively changed by the imparted functionality without altering bulk properties.…”

The interest in developing antimicrobial surfaces is currently surging with the rise in global infectious disease events. Radiation-induced graft copolymerization (RIGC) is a powerful technique enabling permanent tunable and desired surface modifications imparting antimicrobial properties to polymer substrates to prevent disease transmission and provide safer biomaterials and healthcare products. This review aims to provide a broader perspective of the progress taking place in strategies for designing various antimicrobial polymeric surfaces using RIGC methods and their applications in medical devices, healthcare, textile, tissue engineering and food packing. Particularly, the use of UV, plasma, electron beam (EB) and γ-rays for biocides covalent immobilization to various polymers surfaces including nonwoven fabrics, films, nanofibers, nanocomposites, catheters, sutures, wound dressing patches and contact lenses is reviewed. The different strategies to enhance the grafted antimicrobial properties are discussed with an emphasis on the emerging approach of in-situ formation of metal nanoparticles (NPs) in radiation grafted substrates. The current applications of the polymers with antimicrobial surfaces are discussed together with their future research directions. It is expected that this review would attract attention of researchers and scientists to realize the merits of RIGC in developing timely, necessary antimicrobial materials to mitigate the fast-growing microbial activities and promote hygienic lifestyles.

“…5 Direct incorporation of antimicrobial agents into PE, such as blending into polymer and coating or adsorbing antimicrobial agents onto PE surfaces, is the most common process of producing antimicrobial PE. 6 Several antimicrobial agents such as nisin or simple antifungal agents such as propionic, benzoic, and sorbic acids (in the form of anhydride for increasing compatibility) have been added to LDPE to produce active packaging for food. These materials may have limited washing durability since they are mostly soluble in water.…”

Radical melt graft polymerizations of low-density polyethylene (PE) during reactive extrusion were investigated. In the absence of any reactive monomer, effects of peroxide initiator concentration and type, reaction temperature, and rotor speed of reactive extrusion on the polymer reactions were studied by monitoring mixing torque, and proper reaction conditions for the grafting reaction were proposed. Afterward, radical melt graft polymerizations of PE with several amide monomers including methacrylamide (MAM), N-tertbutylacrylamide (NTAAM), and N-tert-butylmethacrylamide (NTMAM) were continued. Fourier transform spectroscopy (FTIR) analysis and nitrogen analysis confirmed that MAM and NTAAM were successfully grafted onto PE. Monomer structures affected grafting efficiency and polymer chain combination. After exposure to chlorine bleach, the graft modified products exhibited powerful antibacterial properties against Escherichia coli and Staphylococcus aureus.
