Effect of morphology control on optical properties of PMMA/boehmite nano-hybrid prepared through facile one-pot process

Aluminum oxyhydroxide-doped PMMA hybrids powder prepared via facile one-pot method towards copper ion removal from aqueous solution

“…However, these materials have some problems of agglomeration, complex separation procedure, and costly recovery methods. Polymethyl methacrylate (PMMA) has been commonly utilized as an adaptable polymer due to its exclusive benefits, such as excellent optical transparency, good solvent resistance, low cost, low density, chemical resistance, and good physicomechanical properties [15][16][17]. These properties enable PMMA to use in many practical applications, for example, optical and supercapacitor, medicine, automobile industries, and hydrogen storage materials [18,19].…”

Protection against a wide UV wavelength range by Bragg reflection from polycrystalline colloidal photonic crystals

“…We used monodisperse poly(methyl methacrylate) (PMMA) particles with a diameter of 160 nm to prepare the colloidal crystals, so that the Bragg reflection wavelength derived from the hexagonal close-packed layers for normal incidence was ∼400 nm, which is the largest wavelength of UV light. Although PMMA has absorption bands in the UV region (200-280 nm), [27][28][29] these bands are out of the wavelength range of the UV light that reaches the earth's surface from the sun (290-400 nm). The colloidal crystals were prepared in a fluidic cell (see the ESI † for details).…”

“…2c. At the concentration of 0.1 vol.%, the Please do not adjust margins Please do not adjust margins spectrum showed a dip at 265 nm due to the absorption band attributed to the carbonyl group in PMMA [27][28][29] (ESI, † Fig. S2) and a high transmittance at a wavelength longer than the dip.…”
