“…One plausible alternative is the development and use of degradable polymer packaging films derived from polyvinyl alcohol [ 5 ], chitosan [ 6 ], starch [ 7 ], and polymer blend substrates [ 8 , 9 ]. However, the degradable polymeric films exhibit inferior mechanical, thermal, and gas barrier properties.…”

Green synthesized metal oxide nanoparticles (NPs) have prominent applications in antimicrobial packaging systems. Here we have attempted for the fabrication of chitosan-based nanocomposite film containing Urtica dioica leaf extract derived copper oxide (CuO) and zinc oxide (ZnO) NPs for shelf-life extension of the packaged guava fruits. Electron microscopy and spectroscopy analysis of the CuO and ZnO NPs exhibited nano-scale size, spherical morphologies, and negative ζ-potential values. The NPs possessed appreciable antioxidant and antimicrobial activity (AMA) in order of CuO NPs > ZnO NPs >nettle extract. Therefore, this work establishes for the first time the successful synthesis of CuO NPs and compares its antimicrobial and antioxidant properties with ZnO NPs. On incorporation in chitosan, the polymer nanocomposite films were developed by solvent casting technique. The developed films were transparent, had low antioxidant but substantial AMA. The NP supplementation improved the film characteristics as evident from the decrease in moisture content, water holding capacity, and solubility of the films. The nanocomposite films improved the quality attributes and shelf life of guava fruits by one week on packaging and storage compared to unpackaged control fruits. Therefore, this study demonstrates the higher antimicrobial potential of the nettle leaf extract derived CuO/ZnO NPs for development of antimicrobial nanocomposite films as a promising packaging solution for enhancing the shelf life of various perishable fruits.

“…Increased use of synthetic packaging films has led to serious ecological problems due to their total nonbiodegradability [1,2]. Thereby, the use of proper packaging materials and methods to minimize food losses and provide safe and wholesome food products had always been the main interest [3][4][5][6][7].…”

In an effort to produce scale-up of edible films, collagen-based films including different amounts of sodium alginate (CS) were prepared by casting method. Films were characterized based on their rheological, thermal, and mechanical properties, water vapor permeability (WVP), and oxygen permeability (OP). The microstructures were also evaluated by scanning electron microscopy (SEM), atomic force microscopy (AFM), and Fourier transform-infrared spectroscopy (FTIR). Furthermore, the addition of sodium alginate effectively improved the viscosity and thermal stability, significantly increased TS, and decreased and WVP ( < 0.05), but with no obvious effect on OP ( > 0.05). SEM and AFM showed homogeneous matrix, with no signs of phase separation in the blends. Overall, films (CS2) produced using collagen (g) : sodium alginate (g) = 10 : 2 showed suitable rheological property (apparent viscosity was 4.87 m Pa s −1 ) and better TS (26.49 Mpa), (64.98%), WVP (1.79 × 10 −10 g⋅cm −1 ⋅s −1 ⋅Pa −1 ), and OP (3.77 × 10 −5 cm 3 ⋅m −2 ⋅d −1 ⋅Pa −1 ).

“…Bands at 2920, 2865, 1405 and 1258 cm −1 were related to symmetrical and antisymmetric C-H vibrations of CH2 [37]. A small shoulder at 1632 cm −1 and the bands at 1554 and 1327 cm −1 can be associated to C=O stretching modes (amide I), N-H deformation modes (amide II) and C-N stretching modes (amide III), respectively [38,39]. The band near to 1026 cm −1 was assigned to stretching vibration C-O of ether and primary alcohol, and can be associated with the presence of glycerol and the piranosydic bonds of chitosan [14,40].…”

From Magneto-Dielectric Biocomposite Films to Microstrip Antenna Devices

Magneto-dielectric composites are interesting advanced materials principally due to their potential applications in electronic fields, such as in microstrip antennas substrates. In this work, we developed superparamagnetic polymer-based films using the biopolymeric matrices chitosan (Ch), cellulose (BC) and collagen (Col). For this proposal, we synthesized superparamagnetic iron oxide nanoparticles (SPIONs) functionalized with polyethyleneimine with a cheap method using sonochemistry. Further, the SPIONs were dispersed into polymer matrices and the composites were evaluated regarding morphology, thermal, dielectric and magnetic properties and their application as microstrip antennas substrates. Microscopically, all tested films presented a uniform dispersion profile, principally due to polyethyleneimine coating. Under an operating frequency (fo) of 4.45 GHz, Ch, BC and Col-based SPION substrates showed moderate dielectric constant (ε′) values in the range of 5.2–8.3, 6.7–8.4 and 5.9–9.1, respectively. Furthermore, the prepared films showed no hysteresis loop, thereby providing evidence of superparamagnetism. The microstrip antennas showed considerable bandwidths (3.37–6.34%) and a return loss lower than −10 dB. Besides, the fo were modulated according to the addition of SPIONs, varying in the range of 4.69–5.55, 4.63–5.18 and 4.93–5.44 GHz, for Ch, BC and Col-based substrates, respectively. Moreover, considering best modulation of ε′ and fo, the Ch-based SPION film showed the most suitable profile as a microstrip antenna substrate.
