“…A significant advantage of nanoparticles (NPs) is their capability to be used in a broad range of applications in a variety of industries, including food, cosmetics, and healthcare. Natural starch is a nonallergic, plentiful polysaccharide that is renewable and biodegradable, making it an ideal candidate to be used in eco-friendly bioformulations . Starch is illustrated as a significant semicrystalline multistate structure that can create new nanoelements .…”

Starch nanoparticles (SNPs) are synthesized by different precipitation techniques using corn starch, and SNP films are prepared by the evaporation casting method. The morphological study is investigated by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The distribution and sizes of precipitated SNPs after synthesizing are discovered by these methods as well. The crystallinity of the SNPs is studied by the X-ray diffractometry (XRD) method that demonstrates reduction compared to neat starch granules, and it is changed from A-style to V H -style after precipitation. The chemical bonding of different SNPs after the nanoprecipitation is analyzed by Fourier transform infrared spectroscopy (FT-IR). Thermogravimetric analysis (TGA) demonstrates the decomposition of starch nanoparticles and the starch matrix that is related to the depolymerization of carbon chains in the range of 260 to 350 °C. The mechanical properties of the SNP films versus the temperature changing are discovered by dynamic mechanical analysis (DMA). The water contact angles of SNP films are measured using a goniometer, and the results showed the hydrophobic surfaces of the prepared films. Our study indicates that SNPs have a promising impact on the properties of corn starch films, which would be useful in biodegradable packaging material.

“…Chitosan is a biodegradable natural nontoxic polymer obtained by deacetylation of chitin, maintaining chelating features and novel polycationic owing to the presence of active hydroxyl and amino functional groups. Consequently, the bene ts of the biopolymer are taken from both chitosan and polyamide and by combining them into a nanocomposite by using the electrospinning method [18][19][20].…”

The principal intention of this work is to fabricate and characterize the polyamide/chitosan nanocomposite by a novel single solvent method through the electrospinning procedure. The thermal properties and morphology of prepared nanocomposite are studied by thermogravimetric analysis (TGA) and eld-emission scanning electron microscopy (FE-SEM). TGA exposed that the primary decomposition temperature is reduced with rising of chitosan content in the nanocomposites and origin disintegration temperature for polyamide/chitosan nanocomposites is perceived to be in the range from 300 to 500°C. Also, FE-SEM images demonstrated that the nano bers of chitosan have good adhesion on the matrix and are well-oriented. Besides, the crystallinity and structural characteristics of the polyamide/chitosan nanocomposites are investigated by using X-ray diffraction (XRD) and Fourier transform-infrared spectroscopy (FT-IR), respectively. The results of XRD proved that the successful blending of chitosan in polyamide is achieved via the electrospinning method. FT-IR results demonstrate that the nano bers are consist of amine groups. Also, the electrical properties of the nanocomposite improved with the increasing content of chitosan and the conductivity of the polyamide/chitosan 5 wt% demonstrates the maximum current of 0.3 nA. Besides, the sheet resistance of the composite reduced 118 to 20 × 10 9 Ω with raising the chitosan volume from 0 to 5 wt%.

“…Penurunan densitas pada penambahan selulosa nanokristal 3% dan 4% disebabkan oleh penambahan pengisi yang berlebihan dapat merusak ikatan antara matriks dan pengisi sehingga menurunkan densitas bioplastik. Selain itu, perbedaan polaritas antara pati, selulosa nanokristal dan gliserol mengakibatkan kurangnya kerapatan struktur bioplastik [22].…”

This study aims to determine the effect of nanocrystalline cellulose and potassium chloride (KCl) to bioplastics from avocado seed starch and glycerol as plasticizer. In this study, nanocrystal cellulose obtained from palm fruit fiber was hydrolyzed using sulfuric acid (H2SO4) at a concentration of 50%. The starch used in this study was obtained from the avocado seed extraction process. On producing bioplastic, the casting method was used with the addition of nanocrystal cellulose as filler of 1%, 2%, 3%, and 4% (%w), KCl as dispersing agent of 0%, 1%, 2%, and 3% (%w), and glycerol as plasticizer by 30 (%w). Based on the density test, the optimum value was obtained at 2% of nanocrystal cellulose and 2% of KCl with the value around 0.041 gram/cm3. The best water absorption values were 57.1% and 53.8% which obtained at 2% of nanocrystal cellulose and 1% of KCl. Scanning Electron Microscope test results showed uniformly distributed nanocrystal cellulose granules filling the surface of the bioplastic. The addition of KCl as dispersion agent give a good impact.
