Thermographic Assessment of Bio-based Materials for Functional and Sustainable End Product

The low biodegradability of synthetic fibers is becoming an increasing concern for sustainability issues. Lately, bio-based materials have attracted remarkable attention, due to their independence of petroleum, as well as eco-friendliness and recyclability. It is estimated that by the end of 2020, the global market of bio-based materials will reach $250 billion, and ten years later, almost one-third of all materials and chemicals will be sourced from biological ingredients. Recently, scientists have given significant effort to improve the degradability of the synthetic fibers and to develop bio-based materials from different renewable resources. Their research is directed towards three main groups of material defined according to the sources: (i) synthetic polymers from natural monomers, including polylactide acid, (ii) polymers from bacterial fermentation, like polyhydroxybutyrate and (iii) natural polymers such as cellulose, protein and starch. The outcomes of published investigations confirmed great potential of bio-based materials in both conventional durable goods and disposable goods. Still, the scientist point out that the use of bio-based materials is limited, mainly due to unsatisfactory or under-researched functionality of end product (primary referring to thermal and mechanical properties). This presentation gives a comprehensive, multi-scale approach for the evaluation of bio-based material functionality by means of thermography, under different simulated thermal environments. The results of measurements confirmed that investigated bio-based materials exhibit great potential for use regarding optimal thermal characteristics, what gives additional incentive to continue the development of bio-based materials and promote their use.
