Recent advances and perspectives on starch Nanocomposites for packaging applications
Journal of Materials Science, 2018Co-Authors: Zainab Waheed Abdullah, Yu DongAbstract:Starch Nanocomposites are popular and abundant materials in packaging sectors. The aim of this work is to review some of the most popular starch nanocomposite systems that have been used nowadays. Due to a wide range of applicable reinforcements, nanocomposite systems are investigated based on nanofiller type such as nanoclays, polysaccharides and carbonaceous nano-fillers. Furthermore, the structures of starch and material preparation methods for their Nanocomposites are also mentioned in this review. It is clearly presented that mechanical, thermal and barrier properties of plasticised starch can be improved with well-dispersed nanofillers in starch Nanocomposites.

Biodegradability and mechanical properties of reinforced starch Nanocomposites using cellulose nanofibers
Carbohydrate Polymers, 2015Co-Authors: Mehran Babaee, Mehdi Jonoobi, Yahya Hamzeh, Alireza AshoriAbstract:In this study the effects of chemical modification of cellulose nanofibers (CNFs) on the biodegradability and mechanical properties of reinforced thermoplastic starch (TPS) Nanocomposites was evaluated. The CNFs were modified using acetic anhydride and the Nanocomposites were fabricated by solution casting from corn starch with glycerol/water as the plasticizer and 10 wt% of either CNFs or acetylated CNFs (ACNFs). The morphology, water absorption (WA), water vapor permeability rate (WVP), tensile, dynamic mechanical analysis (DMA), and fungal degradation properties of the obtained Nanocomposites were investigated. The results demonstrated that the addition of CNFs and ACNFs significantly enhanced the mechanical properties of the Nanocomposites and reduced the WVP and WA of the TPS. The effects were more pronounced for the CNFs than the ACNFs. The DMA showed that the storage modulus was improved, especially for the CNFs/TPS nanocomposite. Compared with the neat TPS, the addition of nanofibers improved the degradation rate of the nanocomposite and particularly ACNFs reduced degradation rate of the nanocomposite toward fungal degradation.

silver nanowire thermoplastic polyurethane elastomer Nanocomposites thermal mechanical and dielectric properties
Materials & Design, 2014Co-Authors: Lih-sheng Turng, Haoyang Mi, Zheng Li, Shaoqin GongAbstract:Abstract Films of polyvinylpyrrolidone (PVP)-stabilized silver nanowire (AgNW)/thermoplastic polyurethane (TPU) elastomer Nanocomposites were fabricated and characterized. With increasing loading levels of AgNW, the transparency of the nanocomposite films was reduced, but their crystallization temperatures increased, suggesting that AgNW could serve as crystallization nucleating agents. The addition of AgNW also enhanced both the Young’s moduli and storage moduli of the nanocomposite films, but caused a reduction in their strain-at-break (from 536% to 304% with 1.5 vol.% AgNW) and ultimate strength (from 12.7 to 9.8 MPa with 1.5 vol.% AgNW). The specific toughness was the highest for Nanocomposites with AgNW loading levels of 0.03 vol.% and 0.05 vol.%. In addition, the dielectric constant of the nanocomposite films with 1.5 vol.% AgNW was 9 times higher than that of pure TPU at 1 kHz, while the dielectric loss of all nanocomposite films studied was less than 0.2. Thus, AgNW/TPU elastomer Nanocomposites with varying mechanical, dielectric, and thermal properties can be engineered by adding a small amount of AgNW. These Nanocomposites can potentially be used for a wide range of applications including dielectric materials.
