A real time study on drying and the mechano-optical behavior of polyvinyl alcohol films in solid and swollen state

PVA hydrogels loaded with a Brazilian propolis for burn wound healing applications

“…The thermal analysis of the samples after immersion revealed that PVA amorphous chains gain movement when in media and the gels can crystallize after swelling/propolis release . In addition, under tensile strain, the chains could pack, leading to high modulus and fracture strength . In Solution pH 4.0, less propolis was released (compared to PBS), and more propolis remained in the network diminishing the possibility of crystallization during tensile tests.…”

Facile and green methodology for surface‐grafted Al2O3 nanoparticles with biocompatible molecules: preparation of the poly(vinyl alcohol)@poly(vinyl pyrrolidone) nanocomposites

“…Partial hydrolysis of poly(vinyl acetate) yields PVA . PVA has two structures: semicrystalline and amorphous .…”

“…PVA has many hydroxyl groups, so it provides the suitable state to be soluble in water and also forms a film . It is also insoluble in most organic solvents . As a result, it is a risk‐free and low‐price polymer with hydrophilic properties …”

“…[14] Partial hydrolysis of poly(vinyl acetate) yields PVA. [15] PVA has two structures: semicrystalline and amorphous. [16] The semicrystalline structure has a vital feature rather than an amorphous one.…”

“…[18,19] It is also insoluble in most organic solvents. [15] As a result, it is a risk-free and low-price polymer with hydrophilic properties. [20,21] When these two polymers are combined, the hydrogen bonding interactions between the PVP and PVA take place via the carbonyl group of PVP and the hydroxyl group of PVA.…”
