The esterification and the multi-carboxyl structure of CA result in chemical cross-linking in the blending system. Furthermore, the esterification happened more easily between the starch and CA than that between the PVA and CA. The residual CA acted as the plasticizer of the starch and PVA. ...
This work focuses on the influence of different amounts (5, 10, 15, 20 and 25%, v/v) of solution of Aloe vera on the chemical structure and properties of sodium alginate/poly(vinyl alcohol) hydrogel films. The polymeric matrix was prepared following the chemical cross-linking method using...
However, integrating high stretchability and sensitivity into a single system is challenging. In this study, sodium carboxymethyl cellulose (CMC) was interpenetrated into an acrylamide (AM), acrylic acid (AAc), and polyvinyl alcohol (PVA) gel matrix to form a three-dimensional structure. Through ...
hydroxyls characterising this 2:1 pattern was thought to be comparable to the nearest oxygen–oxygen distance characterising the pristine crystalline structure of the primary prismatic ice surface. As no simulations of the actual growth of the ice front were included (i.e. PVA bound on a static...
This attests to a growth in both the disordering degree of the polymer film structure and the localized states in the forbidden band gaps and thus a decrease in optical energy gap values. Besides, there is a more significant possibility of transitions from tail to tail and from band to ...

They have ascribed the brilliant spherulites to the crystalline structure and the dark regions to the amorphous phase. The dark boundaries between the spherulites are typically assigned to the presence of amorphous phase29. But in the current work the brilliant regions are ascribed to the ...
