Cellulose is a strong, readily available biologically sourced polymer with a wide potential for applications in many fields. Its high degree of biodegradability makes it an excellent candidate for environmentally friendly sensors, but it is necessary to devise a method by which to render it conductive. Silver nanowires are highly conductive nanoparticles with many potential applications in sensing, as well as being on a similar order-of-magnitude in size as cellulose derivatives, which makes them a prime candidate for use in this application. Methods of casting cellulose nanofibrils (CNF), cellulose nanocrystals (CNC), and TEMPO-Oxidized CNF (TEMPO CNF) films were explored, and …

The University of Maine is one of the world’s leading producers of cellulose nanofibers (CNF). This material has the power to revitalize the Maine paper industry. This has led to an abundance of labs on campus researching applications for the material. Active research activities at the University of Maine include industrial applications such as filtration, biodegradable packaging, building materials and niche health care applications. Niche health care applications include wicking pads for point of care diagnostics and tunable biomaterials ranging from dressings to implantable bone-like materials. Medical applications require an analysis of the biocompatibility of CNF.CNF is biocompatible in general: …
Use Of Renewable Cellulose Nanofibrils And Water-Barrier Layers In The Production Of Snack Packaging, Thoalfakar Saheb Alsaady

From potato chips to chocolate bars, snack packaging requires materials that have excellent water vapor and oxygen barrier properties, good mechanical behavior, and good grease resistance. The most common material used in snack packaging is polypropylene (PP) layer that has been aluminum coated or metalized on one surface. The problem is not only that non-renewable petroleum is used to produce the plastic, but the production of aluminum requires large energy inputs and generates toxic wastes. In addition, this current packaging does not break down in the environment and cannot be recycled. This research is looking at using layers of cellulose …

Cellulose nanofibrils is one of the future potential giants in the medical implant industry. Its unique properties make it the ideal material for use in both permanent prosthetic devices and non- permanent implants such as screws and plates. To increase the usability of this material, the addition of super paramagnetic iron oxide nanoparticles is needed to gain MRI and X-Ray visibility. The methodology for how to homogeneously integrate these particles into the system using the addition of coating agents is explored. This research demonstrates that the addition of coating agents to the iron oxide nanoparticles can affect both the pH …
