“…This phenomenon could be attributed to the great hydrophilicity of Gu, which can attract water molecule and even build a weak gel network with a cavity in the chains of Ge and Gu. The WVP variation trend was consistent with that of Gu–potato starch films (Nandi, & Guha, 2018). Moreover, the high WVP film was very suitable for the packaging of high moisture food, which can inhibit microbial spoilage by reducing the relative humidity.…”

“…Gu achieves excellent freeze‐thaw stability and is the most economical thickener for stabilizing foods (Nieto, 2009). Now, Gu is available for the development of edible films (Jia, Fan, Li, Duan, & Fan, 2017; Nandi, & Guha, 2018; Saurabh et al., 2015; Saurabh, Gupta, & Variyar, 2018). There is a significant synergistic effect of Gu with chitosan and starch according to previous research (Arfat, Ejaz, Jacob, & Ahmed, 2017; Liu et al., 2020; Nandi, & Guha, 2018; Rao, Kanatt, Chawla, & Sharma, 2010; Tang, Zhang, Zhao, Guo, & Zhang, 2018).…”

Demand for antimicrobial packaging films is growing due to public attention to food safety. The structures and properties of gellan gum–guar gum blend films incorporated with nisin were investigated in this paper. Fourier transform infrared spectroscopy, rheological analyses showed intermolecular interactions among gellan gum, guar gum, and nisin. Furthermore, scanning electron microscopy and thermogravimetric analysis also indicated higher compatibility of the blend film components and better thermal stability than the gellan gum film. Tensile strength (TS), elongation at break (EAB) and water vapor permeability (WVP) of the blend films were enhanced with the addition of guar gum. The TS of the blend film reached 2.89 × 103 MPa, the EAB increased to 67.99%, and the WVP increased to 1.80 × 10−5 g/mm·s·Pa. Additionally, the film with nisin had antibacterial activity for Bacillus subtilis. The results demonstrated that a homogenous and smooth antimicrobial film with gellan gum, guar gum, and nisin could be a good option of antimicrobial packaging film for food preservation. Practical Application This work investigated blend package films of gellan gum and guar gum incorporated with nisin. The results showed compatibility and thermal stability of the film were improved with adding a certain amount of guar gum, and also antibacterial activity for Bacillus subtilis of the blend film with nisin. Therefore, it can be used to the development of antimicrobial packaging films.

“…GG serves to enable slurries with higher solid contents, acting as an emulsifier and stabilizer, allowing for a much easier slurry mixing. In fact, the advantageous interaction of GG with starches is well known in the food industry, in which it is used, among other things, to reduce the starchy texture of soups and avoid syneresis (the expulsion of water from the polymer network) .

Natural Polymers as Green Binders for High‐Loading Supercapacitor Electrodes

2020

The state‐of‐the‐art aqueous binder for supercapacitors is carboxymethyl cellulose (CMC). However, it limits the mass loading of the coatings owing to shrinkage upon drying. In this work, natural polymers, that is, guar gum (GG), wheat starch (WS), and potato starch (PS), were studied as alternatives. The flexibility and adhesion of the resulting coatings and electrochemical performance was tested. The combination of 75:25 (w/w) ratio PS/GG showed a promising performance. Electrodes were characterized by SEM, thermal, adhesion, and bending tests. Their electrochemical properties were determined by cyclic voltammetry, electrochemical impedance spectroscopy, and cycling experiments. The PS/GG mixture conformed well to criteria for industrial production, enabling mass loadings higher than CMC (7.0 mg cm−2) while granting the same specific capacitance (26 F g−1) and power performance (20 F g−1 at 10 A g−1). Including the mass of the current collector, this represents a +45 % increase in specific energy at the electrode level.

“…At the same time, in the field of biodegradable materials, there are many cases of introducing biological components into resin matrix to give us some inspiration. From previous studies that produced bioplastics from starch, protein or inorganic filer [10][11][12][13][14], considering that algae from Lake Chao are rich in phyco-protein and polysaccharide [15][16][17][18][19], if the properties of the biomacromolecules can be changed through physical or chemical means, the biomacromolecules can be used to prepare plastic products [20][21][22][23][24][25]. For example, edible biofilms or packaging materials were prepared using starch and protein as raw materials or by using the properties of hydroxyl groups in protein macromolecules grafted with compatibilizers [26,27], such as maleic anhydride, by introducing biomacromolecules into the low-density polyethylene (LDPE) chain [28,29].…”

In order to realize the resource utilization of bloom algae from Lake Chao, this study presents the use of fresh algae to improve the mechanical and biological properties of low-density polyethylene (LDPE). In this study, the algae and LDPE were used as raw materials, maleic anhydride grafted polyethylene (PE-g-MAH), polyethylene wax (PE-wax) and white oil, and glycerin were used as the compatibilizer, lubricant, and plasticizer, respectively. The single factor experiments were conducted with these three individual factors, and the response surface methodology technique was used to optimize the process conditions. In the single factor experiments, the mechanical properties of the composites increased with additions of PE-g-MAH, PE-wax/white oil, and glycerin. Both flexural strength and flexural modulus were maximized to optimize the preparation conditions. The optimum preparation conditions were found as follows: algae powder of 15.00 wt%, LDPE of 85.00 wt%, PE-g-MAH of 4.00 wt%, lubricant of 2.67 wt%, and glycerin of 3.00 wt%. This resulted in 11.60 MPa of tensile strength, 9.95 MPa of flexural strength, and 241.00 MPa of flexural modulus. The mechanical properties of composites were greatly improved compared with the absence of additives. In addition, compared with LDPE resin, the degradability of the composite was improved, and the weight loss rate was 7.73% after 6 months. The results recommended that the composites of the algae from Lake Chao and LDPE resin could be a useful material in the packaging field. Generally, the prepared composite particles can be used to produce foam products, packaging bags, or hard packing boxes with special shapes. It is more environmentally friendly, and more able to meet the challenges of sustainable development.
