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 …

2019年1月1日 · 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.

2023年2月7日 · This review focuses on the applications of FDM in drug fabrication using poly(vinyl alcohol) (PVA) and poly(vinyl pyrrolidone) (PVP) as drug-loaded matrices.

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.

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.

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.

2019年12月10日 · PVP固体胶是一种新型环保固体胶，以PVP ( PVP = Polyvinylpyrrolidone，化学名称为聚乙烯吡咯烷酮，为一种水溶性高分子聚合物，其单体为N-Vinylpyrrolidone (N-乙烯基-2-吡咯烷酮)，是性能优异、用途广泛的水溶性高分子化合物，属高科技含量、高附加值精细化工产品，是国际倡导的重要化工中间体和医药中间体。 作为主料，具有粘度高，无毒环保等特点的 …

2019年1月1日 · During this survey, we found that although PVA-based hydrogels present very good characteristics, some limitations 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.

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.

Polyvinylpyrrolidone/vinyl acetate (pvp/va) resins are linear, random copolymers produced by the free-radical polymerization of the monomers in ratios varying from 70/30 to 30/70 vinyl acetate to vinylpyrrolidone.
