“…Although some MMT might be aggregated with BW, it still lowered the WVP of the BW‐MMT films. This result corresponded to the results for composite films such as cassava starch (Kampeerapappun et al ., ), thermoplastic starch (Park et al ., ), guar gum (Saurabh et al ., ) and soluble soybean (Noghabi et al ., ).…”

“…1. Addition of BW resulted in the appearance of two new peaks at wavenumbers 2848 and 1740 cm -1, which contributed to the stretching vibrations of the C-H groups (Klangmuang & Sothornvit, 2016) and to the C-O-C groups of aldehyde (Saurabh et al, 2016), respectively. Likewise, BF-BW had a wider peak area in the region 1014-995 cm À1 compared to the BF film, which might indicate the presence of the BW and SA in the BF-BW film surface (Fig.…”

“…Beeswax (BW), a natural wax produced by honey bees of the genus Apis, is composed of many long-chain alcohols and the esters of fatty acids. BW has been reported to improve the water barrier properties of hydroxypropyl methylcellulose (HPMC) composite coated paper (Sothornvit et al, 2009), high amylose starch-glycerol films (Muscat et al, 2013), HPMC films (Klangmuang & Sothornvit, 2016) and guar gum film (Saurabh et al, 2016).…”

Summary Unripe banana flour (BF) has potential as an edible film but its hydrophilic nature requires amendment to provide a better water barrier. Beeswax (BW) and montmorillonite Na+ (MMT) are typically applied as reinforcing additives to obtain a water barrier, water solubility and mechanical strength in a biopolymer. Thus, the objective of this study was to investigate the effect of BW, MMT and their combination on banana biocomposite film properties. The results suggested that the addition of BW enhanced the film transparency and water barrier properties. However, the incorporation of MMT increased the water resistance as expressed through low water solubility. Nonetheless, the addition of BW and BW‐MMT reduced the mechanical properties (tensile strength and elongation at break) of BF‐BW and BF‐BW‐MMT films. Nonetheless, the added MMT did not change the mechanical properties of the BF film due to the poor dispersion quality of MMT as confirmed by scanning electron microscopy.

“…The superhydrophobic cotton fabric could selectively absorb oil from oily water and could separate various oil/water mixtures with a separation efficiency higher than 98%. 37 Cationic guar gum was also reported 38,39 to be used in the fabrication of biodegradable films because of its water solubility, film-forming ability, and high viscosity at low concentration. Yan et al 36 constructed antifouling chitin nanofibrous membranes (CNM) via filtration of a chitin nanofiber suspension.…”

In an effort to develop a membrane system with low cost and easy fabrication process for oil/water separation, cellulose nanocrystals (CNC), chitin nanocrystals (ChiNC), and cationic guar gum (CGG) are used to prepare a complex membrane on top of a poly(ethylene terephthalate) (PET) nonwoven fabric via a vacuum filtration method. The interactions among CNC, ChiNC, and CGG complexation are discussed, and the functionalization of the PET nonwoven fabric with these polysaccharide derivatives provides a high rate of water absorption and permeability on applying pressure. The morphology and wettability studies demonstrate that the asprepared membrane has a porous structure and exhibits hydrophilic and underwater superoleophobic properties. The results of separation experiments show that the membrane can effectively separate oil/water emulsions with a relatively high flux and rejection ratio. This low-cost process can easily be scaled up to fabricate complex membranes for oil/water separation.
