Tiivistelmä
Biobased materials are leading a new trend in the development of potential applications nowadays. In this connection, sustainable green chemistry is promoted in public awareness. One of the best candidates in this concept is tannin derivatives which should not be neglected. With excellent properties related to biological, mechanical, physical, and chemical characteristics, tannin-based materials have been designed to gradually replace toxic fossil-based raw materials in certain applications. To fulfill and develop such a new formulation of tannin characteristics, condensed tannins are paid more attention due to their market and applicability.
Apparently, the diversity of tannin derivatives is spread over a vast number of its application from pharmaceutical and nutraceutical applications to the leather manufacturing and beverage sectors. However, in the realm of tannin chemistry, there are a few promising applications which are not yet commercialized. As an example, tannin-based wood adhesives can be used to replace hazardous synthetic compounds, thereby eliminating the emissions of volatile organic substances and formaldehyde compounds. Furthermore, tannin derivatives can also be synthesized with other compounds to enhance the bio-durability properties of wood in the preservative industry. Additionally, tannin-based foaming materials can be used in the construction industry, especially insulating materials, to improve fire resistance and water repellence. Moreover, certain drawbacks in applying tannins to new promising applications are highlighted, from which further research can be conducted in the future.
The thesis topic was taken from the Green Bioraff Solutions (GBS) project from Research and Development of Centria University of Applied Sciences. The object of this study is to stand a chance of gaining a deeper insight into tannins in the field of tannin chemistry. Furthermore, the focus of this study will be to exploit the potential applications of tannin derivatives based on the literature review, and thus no laboratory work is required in this report.
