“…This categorically explains the higher stability of heat-treated PVA nanofibres. Since higher heating temperature and prolonged exposure increases crystallinity [41][42][43], was proven by FT-IR and DSC results, weight loss ratios decreases. Although 24 h methanol-treated HMW PVA nanofibres had crystallinity as high as heattreated samples, the weight loss ratio is a lot higher.…”

“…temperature and pressure [48]. It has been found that in PVA crystallinity increases at temperatures above the glass transition temperature [49]. Therefore it is expected that the crystallinity of the PVA/GO films was affected by the dehydration treatments, while cross-linking (which occurs at >150°C) would be much less significant due to the relatively low treatment temperature.…”

“…Las reacciones de reticulación consumen grupos hidroxilos, lo que conduce a una disminución de la rigidez comparando con el polímero puro. Por otro lado, el entrecruzamiento reduce la movilidad segmental de las cadenas poliméricas lo que provoca aumento de la rigidez [9].…”

“…Posee características únicas como formador de películas, es utilizado en diversas aplicaciones como adhesivo, engomante y espesante, debido a su solubilidad en agua. También es un polímero de baja toxicidad y biocompatible bajo investigación en aplicaciones biomédicas [9]. Para lograr una estabilidad química adecuada, una membrana constituida de PVA necesita ser entrecruzada antes de aplicarse a separaciones de mezclas por pervaporación [10].…”
