Biocompatible UV-absorbing polymer nanoparticles prepared by electron irradiation for application in sunscreen

Abstract

The electron-irradiated polymer nanoparticles exhibit no significant signs of cytotoxicity and phototoxicity while providing excellent UV-shielding performance.

Synthesis of Biobased Poly(butylene Furandicarboxylate) Containing Polysulfone with Excellent Thermal Resistance Properties

“…The absorbance of the copolyester in the UV–visible spectrum was quantitatively determined and the resulting values were graphically represented. As illustrated in Figure S2, a notable increase in the addition of the oligomer HEPES correlates with a marked enhancement in the color intensity observed in the UV–visible absorption spectrum of the copolyester. , These findings collectively underscore the considerable potential of PBFES as a transparent material for packaging applications.…”

MoS2-functionalized conductive carbon heterostructure embedded with ferroelectric polymers for bipolar memristive applications

“…The UV-visible spectra of PMMA (figure S1(a)) display a weak peak near the UV region (∼270 nm), originating due to excitonic transitions within the carbonyl chromophore (C=O). The absorbance gradually decreases in the visible regime with increasing wavelength, confirming the transparency of the PMMA matrix [36]. The PVDF and polymer blend exhibit relatively lower absorbance in the UV region (figure S1(a)) with a broad hump at 270, 314, and 392 nm.…”

Optical and UV Shielding Properties of Inorganic Nanoparticles Embedded in Polymethyl Methacrylate Nanocomposite Freestanding Films

“…However, including inorganic ingredients TiO 2 , CNT, and CQD can improve biocompatibility, reducing polymer degradation [ 47 ]. Although opaqueness and photocatalytic effects are improved, the effect depends on filler material size and other properties, deviating from optical properties [ 46 , 48 ]. TiO 2 -incorporated polymer nanocomposite films can act as excellent anti-fouling and self-cleaning coatings.…”
