The effect of selected components of electronic nicotine inhalers on the process of aerosol formation and its properties

Abstract

The widespread awareness of harmfulness of smoking has contributed to the search for an alternative solution for delivering nicotine to the body. The revolution on the market was the appearance of electronic nicotine inhalers, i.e. e-cigarettes. Despite the controversy, devices of this types are gaining more and more popularity. It became a stimulus to begin the search for possible dependencies between the construction of devices, the way they are used, and the composition of inhalation fluids on the properties of the released aerosol. The scope of this thesis includes a review of literature and internet sources on general construction and principle of operation of electronic cigarettes, their detailed constructional solutions and the most important information on inhalation fluids, so-called e-liquids. Moreover, the analysis of factors with the potential impact on the properties of released aerosols was carried out, as well as a detailed description of the research methodology. As part of the experimental part, tests were carried out aimed at measuring the size distribution of aerosol droplets released from popular models of e-cigarettes under conditions defined by selected values of air flow drawn through the devices, as well as various settings of the heater's power. In addition, the influence of heating systems construction and their resistance to the properties of the released aerosol was examined. Based on the obtained results, it was found clearly visible impact of the air flow rate acquired by the e-cigarette, as well as the power of the heating system on the properties of the released aerosol, i.e. in conditions of high heater power and low air flow rate e-cigarettes release the aerosol with largest droplets.. In addition, the effect of the composition and properties of inhalation fluids as well as the resistance of the heaters used on the median volume distribution of droplets was noted. As the viscosity increases, the size of generated particles decreases, and the use of lower resistance heaters leads to an aerosol characterized by a higher median. The presented research may be a starting point for considerations aimed at assessing the harmfulness of using e-cigarettes, which in the face of their enormous popularity has an extremely important social dimension.
