Polyvinyl alcohol: A review of research status and use of polyvinyl alcohol based nanocomposites

Abstract

This review presents the nature, fundamental structure, and various morphologies of native poly(vinyl alcohol) (PVA) matrix. It highlights recent advances in pure PVA and its composites containing various nanofillers that have potential applications in various fields. Over half a century, PVA is known as an auspicious material for diverse applications. The review focuses on the structural, mechanical, optical, and electrical properties of PVA‐based nanocomposites. The study highlights a new promising area of optoelectronics for possible applications of PVA nanocomposites. The challenges and opportunities in working with various PVA nanocomposites are discussed along with some future recommendations are presented to strengthen this area of research. POLYM. ENG.

High catalytic performance of the first electrospun nano‐biohybrid, Mn3O4/copper complex/polyvinyl alcohol, from Amaranthus spinosus plant for biomimetic oxidation reactions

“…The presence of Mn 3 O 4 nanoparticles in the fibers can be verified by the observation of new characteristic peaks (730 cm –1 ) corresponding to the frequencies associated with the stretching metal‐oxygen of metal oxide nanoparticles. The peak observed at 736.81cm –1 may be attributed to the O atoms in the Mn‐O layers . The peak at 817.82 and 852.54 cm –1 may be due to overtone modes of bulk Mn‐O stretching's Mn 3 O 4.…”

Tensile Fatigue of Poly(Vinyl Alcohol) Hydrogels with Bio‐Friendly Toughening Agents

“…Given PEGDMA may be insufficient in terms of its strength for “permanent” replacement of articular cartilage, one such polymer that is both biocompatible and processable as a hydrogel for this particular application is poly(vinyl alcohol). [ 45 ]…”

“…Given PEGDMA may be insufficient in terms of its strength for "permanent" replacement of articular cartilage, one such polymer that is both biocompatible and processable as a hydrogel for this particular application is poly(vinyl alcohol). [45] Poly(vinyl alcohol) as a hydrogel holds great promise as a synthetic cartilage implant due to its mechanical, chemical, biodegradable, and swelling properties. [11,12,16,[46][47][48] PVA hydrogels can be prepared with nontoxic reagents as well as under physiological conditions that minimize harmful responses from cells and tissue alike.…”

Development and characterization of nano‐crystalline cellulose incorporated poly(lactic acid) composite films

“…include its low toxicity, fast rate of decomposition, easy process ability, renewability, high mechanical strength, and energy saving. Poly (lactic acid) has wide applications in the fields of textiles, biomedical, food packaging, cosmetics and tissue engineering [2][3][4].…”

“…Cellulose is a natural polymer found abundantly in the world. Besides its conventional uses in tex-tiles and clothing, cellulose has recently been employed as nanofiller in nanocomposite formation [5]. Cellulose fiber, as renewable and biodegradable source, is becoming an alternative reinforcing filler due to its good mechanical properties even at particle scale.…”
