TL;DR: Atomic layer deposition of Al2O3 on electrospun poly(vinyl alcohol) microfiber templates is demonstrated as an effective and robust strategy by which to fabricate long and uniform metal-oxide microtubes.

TL;DR: In this article, the role of different polymer reactive groups in film growth and how the balance between precursor diffusion and reaction can change as deposition proceeds is discussed. But the authors focus on the common Al2O3 reaction sequence using trimethyl aluminum (TMA) and water.

TL;DR: In this article, cross-sectional transmission electron microscopy images of polypropylene fibers coated at higher temperature (90 °C) showed that non-coalesced particles formed in the near surface region of the polymer, and the particles grow in size and coalesce into a film as the number of ALD cycles increases.

TL;DR: Infrared analysis shows that ALD can produce a uniform coating throughout the nonwoven polypropylene and woven cotton fabric materials, and the amount of coating can be controlled by the number of ALD cycles.

TL;DR: In this article, an atomic layer deposition (ALD) exposure sequence was used to quantify the reaction between vapor-phase precursors and common polymers with different substituents using in situ infrared transmission analysis.
