PVA-Assisted Synthesis and Characterization of CdSe and CdTe Nanowires
, 2016 CdSe and CdTe nanowires were prepared through a poly(vinyl alcohol) (PVA) assisted ethylenediamine solvothermal method in 160−180 °C. The PVA used in the process was favorable for the formation of nanowires.

Development and Characterization of a Poly Vinyl Alcohol)/Graphene Oxide Composite Hydrogel as An Artificial Cartilage Material [PDF]
, 2018 Poly (vinyl alcohol) hydrogel (PVA-H) is expected to be a suitable artificial articular cartilage material because of its high biocompatibility. However, it is difficult to affix to the surface of a living joint because it is bioinert and its mechanical ...

Advanced Functional Materials, EarlyView.Local polar frustration is engineered to stabilize an ergodic relaxer through nanoscale multiphase coexistence, suppressing long‐range ferroelectric order while preserving high polarization. This strategy delivers ultrahigh low‐field normalized energy density (Wa >0.020 mC cm−2), exceptional thermal stability, and a transferable design principle for ...

Advanced Functional Materials, EarlyView.This work developed an all‐aqueous freeze‐thaw strategy to create a dual‐conductive PVA/P3KBT binder for high volume‐change lithium–ion battery anodes. The resulting binder system strengthens the electrode structure, supports ion and electron transport, and accommodates repeated volume changes, reducing cracking and improving long‐term cycling ...

The Protective Action of Polyvinyl Alcohol(PVA)in PVA Photographic Emulsion
The Journal of the Society of Chemical Industry, Japan, 1963 種々の条件における臭化銀に対するポリビニルアルコール(PVA) の保護作用は比較的希薄なPVA溶液中で多量の臭化銀を生成させ,臭化銀がエマルジョンとして溶液中に残存した量を測定することにより比較を行なった。硝酸銀および臭化カリウムを過剰にした場合,乳剤は僅かに銀イオンの過剰のとき最も安定し,これよりも銀イオン濃度が増せば急激に凝集が起こり,これに対し臭素イオン過剰の場合は徐々に凝集が起こり,臭素イオン濃度が増せば保護作用は低下する。また部分ケン化PVAは完全ケン化PVAよりも保護作用が大きい。PVAでは残存する僅かの酢酸基の量が保護作用に大きな役割を果す。重合度については高いものほど保護作用は大きい。温度の影響は生成した臭化銀自体の性質に大きく及ぼし,PVAの保護効果は明確に現われない。

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly
Advanced Functional Materials, EarlyView.Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...
