Sustainable Carbon Materials and their Composites
Multifunctional nanostructured materials are finding application in a range of sectors such as energy production and storage, catalysis, sensing and biomedicine. Advanced carbon materials possess unique properties such as: high electrical conductivity, high chemical and thermal stability, low toxicity, and ease of chemical functionalisation. However, the vast majority of their synthetic routes involve petroleum based materials. This is a major problem of growing concern as these raw materials are obtained from non-renewable sources involving high energy consumption with ever increasing CO2 emissions and environmental pollution. It is of utmost importance to find alternative sustainable sources for synthetizing these materials. Here, we consider biomass, in particular lignocellulose feedstocks which are advantageous compared to the other biomass sources, in that they are derived from non-edible parts of plants. Coupled to this, forestry, agricultural and agroindustrial lignocellulosic wastes are accumulated every year in large quantities without any valuable application. However, the aromatic structure of lignin enables great potential for valorization through the production of carbon materials via condensation of phenolic rings during pyrolysis. The focus of this work is to produce new carbon materials at both the micron and nano scale. These materials can processed using a UL patented microwave heating process with associated dramatic reductions in carbon emissions. The materials are used to produce composites and nanocomposites for various engineering applications.
