The invention relates to a polypropylene melt-blow non-woven filter material in particular to an antibacterial polypropylene melt-blow non-woven filter material and a preparation method thereof The polypropylene melt-blow non-woven filter material is prepared from the following raw materials in parts by weight: 85-95 parts of melt-blow polypropylene slices 1-5 parts of nanometer tourmaline
Jun 04 2016Polypropylene (PP)/silver nanoparticles (AgNPs)-zeolite plastics were prepared by melt blending PP with AgNPs-zeolite at various AgNPs content of 0 40 80 and 160 ppm in a twin-rotating-screw extruder for inducing antimicrobial activity Mechanical properties and antibacterial efficacy of the prepared PP/AgNPs-zeolite plastics were investigated
Antimicrobial additives for plastics and polymers Biomaster antimicrobial additives are suitable for almost all standard thermoplastics engineering plastics and high-performance plastics including Acrylonitrile butadiene styrene (ABS) Ethylene vinyl acetate (EVA) Polyethylene (PE) Polypropylene (PP) and Polyvinyl chloride (PVC)
However the surface of these TENGs is easily contaminated and breeds bacteria which is a threat to human health Here we report an antibacterial composite film-based triboelectric nanogenerator (ACF-TENG) that uses Ag-exchanged zeolite (Ag-zeolite) and polypropylene (PP) composite film as the triboelectric layer
The present invention discloses a polymer-based silver- carrying graphene nano antibacterial material preparation method a polymer-based silver- carrying graphene nano antibacterial material comprises 75 to 90 by weight parts of matrix resin 10 to 20 by weight parts of a polystyrene / silver- carrying graphene composite and 0 05 to 0 2 by weight part of an antioxidant the preparation
Aims: To develop novel polypropylene composite materials with antimicrobial activity by adding different types of copper nanoparticles Methods and Results: Copper metal (CuP) and copper oxide nanoparticles (CuOP) were embedded in a polypropylene (PP) matrix These composites present strong antimicrobial behaviour against E coli that depends on the contact time between the sample and the

NANO material: antibacterial polypropylene yarn 08 03 2020 PROLENSILTEX is a special polypropylene yarn treated with a permanent antibacterial additive based on silver phosphate glass PROLENSILTEX is effective against the growth of bacteria and unpleasant smells for hygienic freshness It is harmless for humans and the environment
In this work antibacterial polyethylene terephthalate (PET) masterbatch (APM) was prepared by melting‐and‐mixing technology with nano‐Mg(OH) 2 as antibacterial fillers and pure‐PET slices as basic materials In addition titanate coupling agents and stearic acid were used as additives to improve the compatibility of nano‐Mg(OH) 2 and PET The scanning electron microscope (SEM
Melt spinning of polypropylene fibers containing silver and zinc nanoparticles was investigated The nanometals were generally uniformly dispersed in polypropylene but aggregation of these materials was observed on fiber surface and in fiber cross-sections The mechanical properties of the resulted composite fibers with low concentration of nanometal were comparable to those for the control
A growing number of wound dressing-related nosocomial infections necessitate the development of novel antibacterial strategies Herein polypropylene non-woven fabric (PP NWF ) was facilely modified with passive and active antibacterial components namely photografting polymerization both N-Vinyl-2-pyrrolidone (NVP) and glycidyl methacrylate (GMA) monomers and the introduction of guanidine
Materials: Commercially available nano zinc oxide antibacterial food containers composed of polypropylene (pp) plastic (Nano center Ltd Shanghai China) were used as the original material and all chemical reagents this experiment used were of analytical grade Solutions were prepared with distilled water (A S Watson Group (Hong Kong) Ltd
Melt spinning of polypropylene fibers containing silver and zinc nanoparticles was investigated The nanometals were generally uniformly dispersed in polypropylene but aggregation of these materials was observed on fiber surface and in fiber cross-sections The mechanical properties of the resulted composite fibers with low concentration of nanometal were comparable to those for the control
46 without a decrease in their antibacterial activities due to the synergistic effects between the Ag NPs 47 and Fe3O4 NPs with large amounts of active sites13 Depending on synthesis conditions various 48 morphologies of hybrid nanoparticles can be achieved14-16 49 Polypropylene is one of the most common polyolefin and remains the most consumed polymer
