چکیده
The purpose of this study was to develop monodispersed polystyrene particles as certified reference materials in accordance with the ISO 17034: 2016 and Guide 35. It can play a significant role especially during COVID-19 pandemic since several covering items such filtering facepiece respirators or medical masks must be investigated for quality operation by various sizes polystyrene. were prepared in-house National Nanotechnology Center (NANOTEC) using polymerization styrene. Each batch preliminary check distribution, aggregation averaged size dynamic light scattering. Then 1% solid suspension deionized water homogeneity testing, stability assessment characterization transmission electron microscope ImageJ software. 100 nm an example has been successfully synthesized fulfilled criteria deviation from nominal value less than ± 10 polydispersity index 0.05. Then, particle statistically analyzed screening test results coefficient variation 10%. Stability consisting short-term testing three different temperatures long-term within 6 months observed carried out. presented maximum acceptable. tests bottle standard between performed randomly sampling. satisfied therefore assigned certify value. Consequently, 105.5 4.6 developed Thailand which similar level accuracy commercial products.

Dispersion Polymerization of Polystyrene Particles Using Alcohol as Reaction Medium
In this study, monodisperse polystyrene nanospheres were prepared by dispersion polymerization using alcohol as reaction medium to prepare colloidal clusters of the latex beads. Polyvinylpyrrolidone (PVP) and 2-(methacryloyloxy)ethyltrimethylammonium chloride (MTC) were used as dispersion stabilizer and comonomer, respectively. The particle size could be controlled by adjusting the reactant com...

متن کاملColloidal Crystals-Self-Assembly of Monodispersed Colloidal Particles-
Colloidal crystals are three-dimensionally periodic lattices assembled from monodispersed spherical colloids. The ability to crystallize spherical colloids into spatially periodic structures has enabled interesting and often useful functionality not only from the constituent colloidal particles, but also from the long-range order exhibited by these periodic structures. A variety of methods by w...
متن کاملPreparation of Silver - Coated Polystyrene Composite Particles
We report a feasible approach to the preparation of monodispersed metal-shell composite microspheres based on a combination of surface reaction and surface seeding techniques. The method was implemented for coating polystyrene (PS) spheres with silver shell having a variable thickness by controlling the amount of reagents in the reaction procedure. These composite spherical particles in dimensi...
