Interfacial interactions/dynamics were studied in silica core–poly (vinyl pyrrolidone)(PVP)
shell nanoparticles with the shell thickness of 1–2 (monolayer), 2–5, 5–15, and 8–25nm
using far-and mid-IR spectroscopy and DSC activation analysis of the glass transition.
Particles were prepared using a pseudo-liquid state procedure. Their geometry, structural
organization and shell uniformity were characterized comprehensively by LTNA, AFM,
QELS, FT-IR and densitometry techniques. As revealed, strong core–shell interfacial …

Interfacial interactions and dynamics were studied in silica and alumina core‐poly (vinyl
pyrrolidone)(PVP) shell nanoparticles with different shell thicknesses starting from 1‐2 nm
(monolayer); their geometry and structural organization were comprehensively
characterized by several techniques. Far‐and mid‐IR spectroscopy, combined with DSC
activation analysis of the glass transition, allowed to register hydrogen bonding and
Lewis/Brønsted interactions, and the multi‐modal glass transition dynamics in PVP …
