The aim of this study was to optimize the preparation method polymethyl methacrylate (PMMA) denture base loaded with nano silver (NAg), more effectively and safely impart sustainable antibacterial functions. NAg solution synthetized mixed acrylic acid methyl methyacrylate (MMA) monomer in order prepare a new type (NS)/polymer specimens (NS/PMMA). surface morphology, mechanical strength, antimic...

X-ray photon correlation spectroscopy (XPCS) is a powerful tool for investigating the dynamics of polymer nanocomposites. In this study, XPCS was utilized to analyze matrix-free nanocomposite consisting poly(methyl methacrylate)-b-poly(butyl acrylate)-g-silica nanoparticles (PMMA-b-PBA-g-SiNPs) during uniaxial elongation and stress relaxation. The effect microphase-separated state PMMA-b-PBA on...

Nanoparticles suspended in polymeric host materials are found to have tremendous potential for various photonic and biological applications due to their unique material properties. Polymethyl methacrylate (PMMA) is known to be one of the best vinyl polymers owing to its excellent dimensional quality, weather resistance, easiness of synthesis, resistance to laser damage, and high mechanical stre...

G/Ag2S composites were synthesized for the first time by a hydrothermal method. X-ray diffraction, scanning electron microscopy, and transmission electron microscopy analysis demonstrated that Ag2S nanoparticles with a diameter of about 130 nm uniformly covered the graphene surfaces. G/Ag2S composites were dispersed in methyl methacrylate (MMA), polymerized at 75 °C for 30-35 min, and finally d...

Passive samplers for moderately hydrophobic organic compounds (MHOCs) (i.e., log Kow ranging from 2 to 5) are under-developed compared to those that target polar or strongly hydrophobic compounds. The goal of this study was to identify a suitable polymer and develop a robust and sensitive film-based passive sampler for MHOCs in aquatic systems. Poly(methyl methacrylate) (PMMA) exhibited the hig...

Despite its widespread application in the fields of ophthalmology, orthopedics, and dentistry and the stringent need for polymer packagings that induce in vivo tissue integration, the full potential of poly(methyl methacrylate) (PMMA) and its derivatives as medical device packaging material has not been explored yet. We therefore elaborated on the development of a universal coating for methacry...

A series of novel zinc oxide / Poly (methyl methacrylate) nanocomposite films with different ZnO contents were prepared through inclusion pre-synthesized nanoparticles. The physical composition and morphology the as-prepared nanocomposites studied by XRD TEM. TEM analyses revealed that nanoparticles have a particle size ~3–5 nm. X-ray diffraction proved presence amorphous PMMA in nanocomposites...

Nanocomposites composed of diblock copolymer/ferroelectric nanoparticles were formed by selectively constraining ferroelectric nanoparticles (NPs) within diblock copolymer nanodomains via judicious surface modification of ferroelectric NPs. Ferroelectric barium titanate (BaTiO3) NPs with different sizes that are permanently capped with polystyrene chains (i.e., PS-functionalized BaTiO3NPs) were...

UNLABELLED Background and aims. Polymethyl methacrylate (PMMA) is widely used for the fabrication of removable prostheses. Silver nano-particles (AgNps) have been added to PMMA because of their antimicrobial properties, but their effect on the mechanical properties of PMMA is unknown. The aim of this study was to investigate the effects of AgNps on the tensile strength of PMMA. Materials and me...

BACKGROUND The extent of the decentration and tilt was prospectively compared between one piece polymethyl methacrylate (PMMA) and three piece PMMA intraocular lenses (IOLs) which were implanted in the capsular bag after performing continuous curvilinear capsulorhexis. METHODS 91 patients underwent a one piece PMMA IOL implantation in one eye as well as the implantation of the three piece PMM...
