“…The hydrogen bonding probably took place between the alcoholic (−OH) side groups of PVA and hydroxyl groups CNCs, as they are both hydrophilic [58,59]. PVA showed a broad peak near 3296-3325 cm −1 , which was identical to the result from Haque et al [60]. The main peak of hemp particle/PVA was at 3294 cm −1 .…”

“…UV-shielding properties of some lignin composite materials reported in the literature are shown in Figure 8. For example, the cotton gin waste/PVA film [60] has full UV-shielding at 400 nm, while the transparency at visible light is only around 20%. The L-CNCs7 20 wt.…”

Lignin is a natural light-coloured ultraviolet (UV) absorber; however, conventional extraction processes usually darken its colour and could be detrimental to its UV-shielding ability. In this study, a sustainable way of fabricating lignin–cellulose nanocrystals (L-CNCs) from hemp hurd is proposed. A homogeneous morphology of the hemp particles was achieved by ball milling, and L-CNCs with high aspect ratio were obtained through mild acid hydrolysis on the ball-milled particles. The L-CNCs were used as filler in polyvinyl alcohol (PVA) film, which produced a light-coloured nanocomposite film with high UV-shielding ability and enhanced tensile properties: the absorption of UV at wavelength of 400 nm and transparency in the visible-light region at wavelength of 550 nm was 116 times and 70% higher than that of pure PVA, respectively. In addition to these advantages, the nanocomposite film showed a water vapour transmission property comparable with commercial food package film, indicating potential applications.

“…Production of biodegradable material from natural materials resources instead of non-biodegradable synthetic polymers increases great attention due to the developing consciousness of the green environment (1)(2)(3)(4). Several researchers have synthesized biodegradation composites, applying many forms of natural polymers as fillers such as cellulose, lignin, starch, chitin, chitosan, soy protein, and wheat protein.…”

Polyvinyl alcohol (PVA) composite films with different hemp protein particles (HPP) as additives were successfully synthesized by a solution casting method. The properties of HPP-based PVA composites films were investigated. The characterizations of pure PVA and PVA composite films were performed regarding Fourier transform infrared spectroscopy (FTIR), ultra-violet (UV-Vis) to investigate the chemical properties. The formation of hydrogen bond in the PVA-HPP films, which could improve the compatibility of the two components was investigated by FTIR spectroscopy and UV-Vis analysis. The overall results showed that a higher loading of HPP into the PVA matrix improved the chemical interactions significantly. The swelling degree decreased while the water contact angle values increased as the HPP content increased.
