Bacterial cellulose for increasing barrier properties of paper products, Amanda Fillat et al, Cellulose , Vol.25 (10). Bacterial cellulose was combined with wood cellulose papers in order to obtain biomaterials with increased barrier properties. Results obtained show the contribution of bacterial cellulose to improve the properties of paper and its potential for the design of new added value paper products from biomass. Enhancement of hydrophobicity of nanofibrillated cellulose through grafting of alkyl ketene dimer, Zhaoyang Yuan et al, Cellulose , Vol.25 (12). To expand the application of nanofibrillated cellulose (NFC), the increase of its hydrophobicity is considered to be critical. In the present work, hydrophobic NFC powder was prepared through chemical modification with alkyl ketene dimer (AKD). The hydrophobicity of AKD-modified NFC increased with increasing AKD graft yield. NOVEL PRODUCTS Paper in Electronic and Optoelectronic Devices, Dongheon Ha et al, Advanced Electronic Materials , Vol.4 (5). Paper, one of the oldest materials for storage and exchange of human's information, has been reinvented as a building component of electronic and optoelectronic devices over the past decades with successful demonstration of paper Ǧ based or paper Ǧ using devices. This article provides a review of electronic and optoelectronic devices relying on or making use of the unique properties achievable with paper Ǧ based materials. Basic scientific/technical principles, quantitative comparisons of material, electronic and/or optical properties, and benefits for each paper Ǧ based application are given. Application Ǧ specific research challenges, future design considerations, and development directions are also discussed. Thermoplastic starch foamed composites reinforced with cellulose nanofibers: Thermal and mechanical properties, Abbas Ghanbari et al, Carbohydrate Polymers , Vol.197. The present work reports the effect of cellulose nanofibers (CNFs) on the thermal, dynamic mechanical analysis (DMA), density and water uptake of thermoplastic starch (TPS) foamed composites. Cellulose and nanocellulose-based flexible-hybrid printed electronics and conductive composites – A review, Sachin Agate et al, Carbohydrate Polymers , Vol.198. Flexible-hybrid printed electronics (FHPE) is a rapidly growing discipline that may be described as the precise imprinting of electrically functional traces and components onto a substrate such as paper to create functional electronic devices. The mass production of low-cost devices and components such as environmental sensors, bio- sensors, actuators, lab on chip, radio frequency identification smart tags, light emitting diodes, smart fabrics and labels, wallpaper, solar cells, fuel cells, and batteries are major driving factors for the industry. The aim of these developments is to enable the creation of FHPE devices and components made almost entirely of cellulose materials. Production of Self-Supported Conductive Films based on Cellulose, Polyaniline and Silver Nanoparticles, Roselaine da S. Oliveira et al, Carbohydrate Polymers , Vol.199. Synthetic efforts are being made to produce electrical conductive films based on a combination of cellulose matrix with conducting polymers. Improved mechanical properties and processability of the conducting polymers can be attained by promoting this combination. The high conductivity was promoted by the presence of polyaniline in its most conductive state with the silver nanoparticles affording the electrical contact among these chains creating a conductive network spread throughout the insulating cellulose matrix.
