    Nanocellulose-Enabled Electronics, Energy Harvesting Devices, Smart Materials and Sensors: A Review

    Ronald Sabo1*, Aleksey Yermakov2, Chiu Tai Law3, Rani Elhajjar4

    Journal of Renewable Materials, Vol.4, No.5, pp. 297-312, 2016, DOI:10.7569/JRM.2016.634114

    Abstract Cellulose nanomaterials have a number of interesting and unique properties that make them well-suited for use in electronics applications such as energy harvesting devices, actuators and sensors. Cellulose nanofibrils and nanocrystals have good mechanical properties, high transparency, and low coefficient of thermal expansion, among other properties that facilitate both active and inactive roles in electronics and related devices. For example, these nanomaterials have been demonstrated to operate as substrates for flexible electronics and displays, to improve the efficiency of photovoltaics, to work as a component of magnetostrictive composites and to act as a suitable lithium More >

    Introduction to the Special Issue on Nanocellulose Composites

    Craig Clemons, Srikanth Pilla

    Journal of Renewable Materials, Vol.4, No.5, pp. 295-296, 2016, DOI:10.7569/JRM.2016.634133

    Abstract Cellulose nanomaterials (CNs) are at the convergence of nanotechnology and bio-sourced material trends and are currently of considerable interest. CNs are a new class of nano-scale, cellulose-based building blocks extracted from trees and plants as well as certain animals, bacteria, and algae. CNs are not a single material type but a family of materials with different characteristics, which largely result from differences in source and preparation methodology. Here we focus on plant- and tree-derived CNs. More >

    Physicochemical and Mechanical Properties of Gelatin Reinforced with Nanocellulose and Montmorillonite

    Mercedes Echegaray1, Gurutz Mondragon1, Loli Martin2, Alba González3, Cristina Peña-Rodriguez1, Aitor Arbelaiz1*

    Journal of Renewable Materials, Vol.4, No.3, pp. 206-214, 2016, DOI:10.7569/JRM.2016.634106

    Abstract Organic rodlike cellulose nanocrystals extracted from sisal fibers and inorganic montmorillonite based on silicate layers were employed to develop bionanocomposites based on gelatin matrix. Bionanocomposites with cellulose nanocrystal, montmorillonite and both nanoreinforcements combined were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis and differential scanning calorimetry. Tensile properties and oxygen and water vapor gas permeability values were determined to study the influence of the addition of nanoreinforcements, different in nature, to gelatin matrix. Bionanocomposites with montmorillonite improved tensile strength but systems reinforced with nanocellulose showed lower tensile strength than neat gelatin ones. Oxygen gas permeability More >
