Abstract

The search for increased value products from the commodity paper and cellulose industry found on nanocellulose � a high performance nanoscale biomaterial discovered by Turbak. Snyder and Sandberg in the ITT Rayonier Labs (New Jersey, USA) in 1978 � an opportunity to reach more profitable markets, such as advanced composites for the auto industry, flexible OLED screens, pharma formulations or advanced biomedical therapies. To understand the evolution of this 40-year technology, and the progress towards industry/commercial applications, the analysis of patent and scientific articles becomes a key information to future investments and efforts towards new nanocellulose-based frontier materials. The purpose of the present study is to propose a technological roadmap of nanocellulose to understand in which direction in which this technology is heading. Patent data search used Questel Orbit and Thomson Reuters� Derwent Innovation Index from Web of Science databases. Scientific articles search used Scopus and SciFinder databases. All gathered information was classified with the following hierarchy: 1. Type of nanocellulose (Nanocrystalline, nanofibrillated or bacterial nanocellulose; 2. Subject (Production process or chemical modification/application); and 3. Country of origin. This classification occurred after a detailed analysis of each searched document. A further analysis associated the documents with a target market/application, creating a table relating it with the type of technology used. The proposed technological roadmap was then created quantifying the tendencies with the industry investments, creating a most probable scenario of the future of nanocellulose and its applications for the mid and long term. Although the early use of nanocellulose, as nanofibrillated cellulose, focused on nanocomposites and their use as rheology modifiers, the new chemical modification methods of bacterial nanocellulose shifted the interest of this material on sophisticated biomedical applications, as well as to nanocrystalline cellulose, with high performance use in photonics and advanced electronics.
