“…For instance, fully hydrolysed PVA is more water-resistant than partially hydrolysed PVA (Limpan et al 2012). Increasing DH also improves the crystallinity and chain mobility of PVA polymer (Hdidar et al 2017).…”

“…In fact, heating to 240 °C of PVA films loaded with OleE and HTyrE will induce thermal degradation of the extracts, altering the thermal response of the PVA matrix. The analysis of the curves ( Figure 8 c,d) showed the presence of a transition, visible at 40 °C, related to wet fraction of PVA [ 47 ]. In fact water acts as a plasticizer in wet samples, so the expected increase in glass transition temperature to about 70 °C in a second heating scan can be explained by the evaporation of water during the first scan reported as an endothermic peak in Figure 8 c,d.…”

“…The second region is a plateau like region which corresponds to the DC conductivity, σ dc . The plateau is clearly visible when the temperature exceeds 85 °C which is higher than the glass transition temperature T g of pure PVA [2]. The third domain corresponds to high frequencies; the conductivity increases when the frequency increases.…”

“…In the recent years, a significant concentration has been pointed to proton-conducting polymers due to their potential uses in various applications such as batteries, sensors, fuel cells, super capacitors, and solar cells [1,2]. In the fuel cell field the electricity production occurs via electrochemical energy conversion using hydrogen and oxygen supply to anodic and cathode compartment [3].…”
