“…The FTIR analysis of unmodified PVA (Figure 2a) revealed characteristic PVA spectra that are in agreement with the literature [18]. We can clearly see the presence of a large peak at 3400 cm can be related to the C-O-S bonds [19].…”

Partial chemical modification of poly(vinyl alcohol) (PVA) was performed through tosylation followed by azidation. Amine functional PVA was also prepared by grafting propargylamine using click chemistry reaction. Through this approach, a tosyl group (a good leaving group), azide group (a group used in click chemistry) and amine group (a group used for amidation) were attached to PVA polymer chains. The three chemical modifications were performed in water. FTIR and XPS analysis confirmed the chemical modification after each step. Thermogravimetric analysis (TGA) was used to study the thermal stability of the modified PVA.

Poly(vinyl alcohol) (PVA) films crosslinked by cinnamaldehyde (CIN) at various concentrations were prepared. Their physicochemical and antibacterial properties were compared with those of uncrosslinked films. The results suggest that the crosslinked films exhibited higher transparency, tensile strength, and elongation at break in a certain CIN concentration range. They also displayed decreased water vapor permeability and water solubility. Although the antibacterial activity of the crosslinked film-forming solution was less slightly than that of the uncrosslinked film-forming solution, the crosslinked film-forming solution still demonstrated strong antibacterial activity when the concentration of CIN was 2% v/v. The aldol condensation reaction between the aldehyde group of CIN and the alcoholic hydroxyl group of PVA was determined by Fourier transform infrared spectroscopy. By the crosslinking reaction, the heat stability of the crosslinked film was enhanced compared with that of the uncrosslinked film. Meanwhile, a compact, smooth, and continuous cross-sectional microstructure present in the crosslinked film was observed by scanning electron microscopy. The higher water resistance and transparency gave the crosslinked films priority for use in food packaging.

“…6,7 As a kind of two-dimension carbon material, graphene and its derivatives exhibited the great potential for the reinforcement of polymer materials. [8][9][10][11][12][13] For example, Wang et al prepared 3-aminopropyl triethoxysilane modified graphene oxide (f-GNS) for the reinforcement of epoxy resin. With 1 wt % of f-GNS, the tensile strength and elongation to failure of epoxy resin increased by 45 and 133%, respectively.…”

Reduced graphene oxide reinforced acrylic rubber (ACM/RGO) was in situ prepared via self‐assembly method in the presence of hydrazine hydrate as reducing agent. X‐ray diffraction and X‐ray photoelectron spectroscopy confirmed the chemical structure of ACM/RGO, and transmission electron microscope and scanning electron microscope demonstrated that RGO was uniformly dispersed in ACM matrix. Due to the barrier role of RGO sheets, the resistances to heat and water of ACM/RGO were obviously improved. Furthermore, the mechanical properties were also largely affected by the incorporation of RGO. With 2 parts per hundred rubber of RGO, the tensile strength and Shore A hardness of ACM/RGO reached 18.8 MPa and 73, and the elongation at break maintained at 236%. © 2018 Wiley Periodicals, Inc. J.
