PVA is known for its strong bond, water resistance, and flexibility, while PvP has a weaker bond, faster drying time, and may be more rigid once dried. Consider the specific requirements of your project when choosing between PVA and PvP to ensure …

Jan 1, 2019 · Due to their excellent mechanical properties, good biocompatibility and biodegradability, PVA, PVP and PVA/PVP-based biomaterials have a well-documented history in a wide variety of advanced applications in biomedical, biotechnological, pharmaceutical, food, industrial, and commercial fields.

Jan 24, 2023 · PVP is more water soluble than PVA glues making it easier to wash off you heat bed. Which is betterr? I got no clue. I have used both and can't the difference in use. PVP is slightly more soluble in IPA and Acetone than PVA, so basically just easier to fully clean.

However, studies revealed that PVA-based biomaterials present some limitations that can restrict their use or performances. To overcome these limitations, various methods have been reported, among which blending with poly(vinylpyrrolidone) (PVP) showed promising results.

This review specifically examines the utilization of environmentally friendly, shapable hydrogels composed of polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) in various casings for crop protection against different pests, fertilizing, and watering.

In this work, PVP/PVA/borax hydrogels with different compositional ratio were prepared by the freezing-thawing technique. The effects of PVP and borax on the hydrogels were evaluated by comparing the physical and chemical properties of the two hydrogels made of PVA/borax and PVA/PVP/borax.

Polyvinyl alcohol (PVA) and Polyvinyl Pyrrolidone (PVP) hydrogels are desirable biomaterials for soft tissue repair and replacement. However, the bio-inertness and poor cell adhesive potency of the PVA and PVP hinder the wide range of biomedical applications.

Apr 18, 2022 · Biocompatible and multifunctional stretchable hydrogels have attracted growing interests for applications including electronic skin and soft robotics. This paper presents a conductive and humidity sensitive hydrogel formed by poly (vinyl alcohol) (PVA) and poly (vinylpyrrolidone) (PVP).

Mar 26, 2022 · The PL of the PVP/PVA blend is tailored to emit spectra in the visible spectrum region;cyan, blue and green colours. The obtained findings of designing the optical and photoluminescent properties of PVP/PVA blend reveal their effective role in …

Jul 24, 2018 · In this review paper, details of synthetic of hydrogel formulations with PVA and PVP for biomedical applications.
