“…This increase was attributed to restricted segmental motion of biopolymer chains in bio‐nanocomposites. Similar results on increase in E ′ and T g of bio‐nanocomposites based on other biopolymers have been reported (Ray and others 2002b; Huang and Netravali 2006; Sasmal and others 2008; Romero and others 2009).…”

The nonbiodegradable and nonrenewable nature of plastic packaging has led to a renewed interest in packaging materials based on bio-nanocomposites (biopolymer matrix reinforced with nanoparticles such as layered silicates). One of the reasons for unique properties of bio-nanocomposites is the difference in physics at nanoscale as compared to that at macroscale. Therefore, the effect of nanoscale on the properties of bio-nanocomposites is discussed. Properties of bio-nanocomposites are governed by the extent of dispersion of nanoparticles in the biopolymer matrix and interaction between nanoparticles and the biopolymer. Selection of proper technique to determine properties of these bio-nanocomposites is very critical in assessing their performance. Experimental techniques (tensile testing, barrier property measurement, dynamic mechanical analysis, differential scanning calorimetry, thermogravimetric analysis, rheological measurement) to determine the mechanical, barrier, thermal, and rheological properties of bio-nanocomposites are discussed in terms of methodology, interpretation of results, and application in studying the properties of bio-nanocomposites. Mathematical modeling plays an important role in predicting the properties of bio-nanocomposites and comparing them to the measured properties. This comparison helps in better understanding the mechanism for much improved properties of bio-nanocomposites. Mathematical modeling is also helpful in understanding the effects of different parameters on the properties of bio-nanocomposites. Therefore, the article describes mathematical modeling of mechanical and barrier properties of bio-nanocomposites using analytical micromechanics.

Conventional nonbiodegradable thermoplastic polymers are mainly utilized by industries for edible and nonedible packaging applications. Various polysaccharides such as soy protein isolate (SPI) were used as a biodegradable polymer on behalf of synthetic polymers. Polysaccharides have superior water vapor permeability properties as compared with other synthetic polymers. In the present study, rheological characterization of SPI/poly(vinyl alcohol) (SPI/PVA) based biocomposite and bionanocomposites were performed. Ecofriendly biocomposite and bionanocomposites were successfully prepared via solution casting technique. Montmorillonite (MMT) was used as a nanofiller to enhance the characteristics of the SPI/PVA matrix. The rheological tests have been carried out to evaluate the viscoelastic behavior of biocomposite and bionanocomposites. Scanning electron microscope (SEM) and polarizing optical microscope (POM) images were evaluated to define dispersion of SPI and MMT in the PVA matrix. The shear-thinning behavior of prepared samples was determined by measuring the viscosity of the polymeric solution. The frequency sweep test was done to govern the long term stability of SPI/PVA/ MMT bionanocomposites. SPI/PVA/MMT (0.7% NC) nanocomposite is more stable in contrary to other prepared biocomposite and bionanocomposites. An amplitude sweep test was conducted to define the linear viscoelastic region.The viscosity of synthesized biocomposite and bionanocomposites was decreased as the shear rate increased at room temperature. Low-cost biocomposite and bionanocomposites have been developed. It is a potential material that has been used as a coating material in the wood and paper industry.

“…Therefore, endowing a surface of implanted medical devices, daily commodities, or equipment with antimicrobial property is extremely necessary in the applications of health care, packaging, water purification, marine biofouling, and textile industry . For this purpose, various antimicrobial materials have been increasingly developed mainly focusing on the introduction of some antibacterial moieties into matrix material, including metal and metal oxides, hybrid particles, quaternary ammonium salts, synthetic, and natural polymers . Particularly, silver nanoparticles (AgNPs) have received extensive attention owing to their wide and extremely effective antimicrobial activity toward various fungi, bacteria, and viruses.…”

A mussel‐inspired strategy toward antimicrobial and bacterially anti‐adhesive soy protein surface

Biopolymer products are widely used in our everyday life, however, the poor antimicrobial nature dramatically limits their applications. Therefore, it is essential to improve the antibiotic performance of these biopolymer products. In this study, soy protein isolate (SPI)-based films with antimicrobial and antifouling function were fabricated through a dip-coating method. Briefly, mussel-inspired polydopamine was coated onto the surface of SPI film, followed by depositing silver nanoparticles (AgNPs) on the film for yielding an antimicrobial film, named S-DA-Ag. Subsequently, octadecyltrichlorosilane (OTS) molecular was attached on the S-DA-Ag film. Elemental and morphological surface analyses verified the successful coating for each step. The S-DA film decorated only with AgNPs exhibited an effective antimicrobial activity against Escherichia coli and Staphylococcus aureus but failed to prevent bacterial attachment. However, the number of attached bacterial cells significantly decreased for the OTS-coated S-DA-Ag film.Additionally, the resultant SPI-based films displayed excellent mechanical performance and remarkably improved water resistance, dramatically benefiting their practical applications. This novel design can endow the antimicrobial and antifouling properties to the SPI-based films and enhance their mechanical properties and water resistance, which might expand their potential applications in the healthcare and biomedical fields.
