Abstract Antibacterial multilayer films containing nanosilver were prepared via layer‐by‐layer fashion. PET film was aminolyzed with 1,6‐hexanediamine to introduce amino groups on surface; chitosan–silver nitrate complex and heparin alternately deposited onto an surface, subsequently, the silver ions within reduced ascorbic acid form nanoparticles. UV–visible spectroscopy transmission electron microscopy confirmed formation of well‐dispersed particles sizes (10–40 nm) that depended initial...
A superhydrophobic/hydrophilic asymmetric free-standing film has been created using layer-by-layer assembly technique. Poly(ethylene-imine)-Ag+ complex (PEI-Ag+) at pH 9.0 was assembled with poly(acrylic acid) (PAA) 3.2 on a Teflon substrate to yield micronanostructured surface that can be turned superhydrophobic after being coated low energy compound. Silver nanoparticle loaded one while the other is hydrophilic then obtained detachment from substrate. The superhydrophobicity enabled upper...
We report a direct method to amplify the exponential growth of multilayers significantly by alternating deposition polyethylenimine (PEI) at high pH and poly(acrylic acid) (PAA) low pH. The switches degree ionization polyelectrolytes in multilayers, which enhances diffusion PEI into out film hence increases deposited mass per cycle. synergetic action pH-tunable charge density diffusivity weak provides new for enhanced with hierarchal micro- nanostructured surfaces.
Abstract The interaction of spores Ulva with bioinspired structured surfaces in the nanometer–micrometer size range is investigated using a series coatings systematically varying morphology and chemistry, which allows separation contributions surface chemistry to settlement (attachment) adhesion strength. Structured are prepared by layer‐by‐layer spray‐coating deposition polyelectrolytes. By changing pH during application oppositely charged poly(acrylic acid) polyethylenimine...
Abstract A multifunctional multilayered film containing TiO 2 nanoparticles as contact‐active antibacterial agent and nanosilver a release‐active was fabricated via layer‐by‐layer assembly. with the anatase crystalline dominant structure were synthesized sol‐gel method. The QCM, AFM, contact angle measurement results indicated that nanoparticle‐chitosan successfully assembled heparin UV visible spectroscopy demonstrated silver ions could be loaded into multilayers in situ synthesize...
A humido-responsive free-standing film has been created using layer-by-layer assembly technique. Polyethylenimine (PEI) at high pH was assembled with poly(acrylic acid) (PAA) low on a Teflon substrate to yield micro-nanostructured surface that can be made superhydrophobic after being coated energy compound. The resulting asymmetric one while the other is hydrophilic detachment from undergo reversible bending/unbending shape transitions when environmental humidity changed. movement of...
The green synthesis of silver nanoparticles (AgNPs) using a water extract Ginger (Zingiber officinale) root by microwave irradiation and its antibacterial activities have been reported. However, AgNPs prepared from different parts ginger or ethanol ultrasound their antioxidant activity whether the biogenic could be used to catalyze reduction hazardous dye are unknown. This study concentrated on facile (unpeeled ginger, peeled peel) ultrasound-assisted method. We studied catalytic degradation...
Nowadays hospitals have been at the forefront fighting against novel coronavirus pneumonia, with diagnosing and treating of patients as a top priority. In order to ensure smooth progress diagnosis treatment, prevent occurrence nosocomial infection, logistics support needs make allowances for isolation ward in time from perspectives logistics, facilities equipment, transform in-and-out double channels access required, thus setting up partition three zones. Secondly, optimize service workflow,...
