Abstract

In this study, we investigate the volatile organic compounds release characteristics of microalgae (Chlorella sp. HS2) in relation to temperature in an effort to realize an alternative type of biomass for use in the fabrication of eco-friendly polymer composites. The volatile organic compounds (VOCs) generated during the compounding process of the polymer composite is quantified and the VOC generation pathways are discussed. As the microalgae are heated and their content in the composites increases, the intensity of the VOC release increases. At a high temperature of 180 °C, a typical polymer processing temperature, microalgae release volatile substances. The VOCs are identified as compounds containing ketone functional groups and benzene derivatives through chromatography and spectrometry analyses. VOCs with ketone functional group can originate from small fatty acids by a complex reaction pathway that includes hydrolysis, oxidation, and degradation, while benzene derivatives are from aromatic amino acids, such as Tyrosine, Phenylalanine, and Tryptophan, contained in the microalgae. The findings demonstrate that microalgae biomass particles produce VOCs during polymer processing, which must be considered during the fabrication and eventual commercialization of polymer composites.

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
