Special Issue Information

Dear Colleagues,

Poly(vinyl alcohol) (PVA) is a versatile synthetic polymer, extensively used in the design of hydrogels, porous membranes, and films. Its solubility in water and some organic solvents (such as dimethyl sulfoxide, dimethylformamide glycols, and acetamide) and its film- and hydrogel-forming capabilities, non-toxicity, crystallinity, excellent mechanical properties, chemical inertness, stability towards biological fluids, superior oxygen and gas barrier properties, good printability, and availability (relatively low production cost), are the main aspects that make PVA suitable for a variety of applications, from biomedical and pharmaceutical uses to optoelectronic devices, pervaporation membranes, sensors, packaging applications, and so forth.

However, pure PVA materials present poor stability in water, temperature sensitivity, limited flexibility, poor biocompatibility, and biodegradability, which restrict its use alone in various applications. PVA blended with other synthetic polymers or biomolecules (polysaccharides, proteins, peptides, amino acids, etc.), as well as inorganic/organic compounds, are attractive because all of the shortcomings of PVA are considerably improved upon and new functionalities are obtained. Also, the chemical derivatization or modification of PVA introduce new features and open the door for various and unexpected uses.

This Special Issue aims to enhance knowledge concerning the latest developments in PVA-based materials, from design and structure to properties and potential applications.

Original research contributions and reviews are all welcome.

The development of a hydrogel material with a modified chemical structure of poly(vinyl alcohol) (PVA) and silk fibroin (SF) using glycidyl methacrylate (GMA) (denoted as PVA-g-GMA and SF-g-GMA) is an innovative approach in the field of biomaterials and meniscus tissue engineering in this [...] Read more.
The development of a hydrogel material with a modified chemical structure of poly(vinyl alcohol) (PVA) and silk fibroin (SF) using glycidyl methacrylate (GMA) (denoted as PVA-g-GMA and SF-g-GMA) is an innovative approach in the field of biomaterials and meniscus tissue engineering in this study. The PVA-g-GMA/SF-g-GMA hydrogel was fabricated using different ratios of PVA-g-GMA to SF-g-GMA: 100/0, 75/25, 50/50, 25/75, and 0/100 (w/w of dry substances), using lithium phenyl (2,4,6-trimethylbenzoyl)phosphinate (LAP) as a free radical photoinitiator, for 10 min at a low ultraviolet (UV) intensity (365 nm, 6 mW/cm2). The mechanical properties, morphology, pore size, and biodegradability of the PVA-g-GMA/SF-g-GMA hydrogel were investigated. Finally, for clinical application, human chondrocyte cell lines (HCPCs) were mixed into PVA-g-GMA/SF-g-GMA solutions and fabricated into hydrogel to study the viability of live and dead cells and gene expression. The results indicate that as the SF-g-GMA content increased, the compressive modulus of the PVA-g-GMA/SF-g-GMA hydrogel dropped from approximately 173 to 11 kPa. The degradation rates of PVA-g-GMA/SF-g-GMA 100/0, 75/25, and 50/50 reached up to 15.61%, 17.23%, and 18.93% in 4 months, respectively. In all PVA-g-GMA/SF-g-GMA conditions on day 7, chondrocyte cell vitality exceeded 80%. The PVA-g-GMA/SF-g-GMA 75:25 and 50:50 hydrogels hold promise as a biomimetic biphasic injectable hydrogel for encapsulated augmentation, offering advantages in terms of rapid photocurability, tunable mechanical properties, favorable biological responses, and controlled degradation.
