“…The thermal event at lower temperature can be attributed to the decomposition by dehydration reaction of hydroxyl groups present in the polymer by the hydrolysis by TFA [52]. Pure oleic acid presented a degradation temperature at 280°C [53,54].…”

“…There are various silanol groups in the nanosilica that can change the crystalline behaviors of the polymeric matrix, increase hydrogen bonding effects, and affect the fluorescent properties of composite end products. Furthermore, thermal resistance is the most significant property of polymeric materials, as it controls their spectral stability, mechanical properties, shelf lives, and durability (Cho et al 2003;Jin et al 2003;Peng et al 2006;Peng and Kong 2007;Saat and Johan 2014). In this paper, the modification of the properties of PVA by the incorporation of highly reactive nanocellulose, isolated from oil palm empty fruit bunches (OPEFB), and nanosilica were studied.…”

This work reported the thermomechanical and morphological properties of polyvinyl alcohol (PVA) nanocomposites reinforced with nanosilica and oil palm empty fruit bunches derived nanocellulose. The nanocomposites were characterized by mechanical, thermal, XRD, optical, and morphological studies. Uniformity dispersion of the nanofillers at a 3 wt% concentration has been shown by scanning electron microscopy, whereas the changes in crystallinity were demonstrated by X-ray diffraction analysis. Addition of nanosilica resulted in increased thermal stability of PVA/nanocellulose composites due to the reduction in mobility of the matrix molecules. Visible light transmission showed that the addition of 0.5 wt% nanosilica only slightly reduced the light transmission of PVA/nanocellulose composites with 3 wt% nanocellulose. The addition of a small concentration of nanosilica successfully improved the tensile and modulus properties of PVA/nanocellulose composite films. The increases in tensile strength and thermal stability were evidence of a nanosilica contribution in PVA/nanocellulose composites, inducing reinforcement, as detected by the thermomechanical properties.

“…For examples, most of the PVA modification reactions involve etherification, 17,18 esterification, 19,20 and acetalization 21,22 via hydroxyl groups. Besides that, sulfonation, 23,24 phosphorylation, 19,25,26 imidization, 27 amination, 28 quaternization, 17,29 azidation, 28 and complexation 30 have also been explored to introduce specific functional groups. In addition, water has been used as a reaction medium for click reaction of imidized‐PVA with porpargylamine, 28 and functionalized graphene oxide 31 to obtain amine‐functionalized PVA and graphene oxide (GO)‐grafted‐PVA respectively.…”

Clean water and energy are two of the most important requirements for human survival. Membrane‐based filtration represents one of the advanced technologies involved in water decontamination; while, polymer electrolyte membrane fuel cells (PEMFCs) are among the frontrunners in the alternative and renewable energy domain. It is evident that membrane‐based processes provide sustainable solution to the ever‐increasing demand of energy and clean water. Over the years, it has been realized that synthetic poly(vinyl alcohol) (PVA) is one of the potential candidates for the development of membranes, owing to its hydrophilicity, barrier property, film forming ability, crosslinking ability, biodegradability, and low cost. These properties have been widely explored for the fabrication of polymer electrolyte membranes for PEMFCs, in order to improve the ionic conductivity and methanol barrier property, as well as, to reduce the membrane fabrication cost. On the other hand, high water solubility and film forming characteristics of PVA have been used for the formation of water treatment membranes, for enhancing the antifouling property and chemical stability. This review provides in‐depth discussions and analyses on the structure and properties of various PVA‐based copolymers, and their applications as membrane materials for PEMFCs (including direct methanol and alkaline fuel cells) and water remediation.
