Facile Fabrication of a Functional Filter Tip for Highly Efficient Reduction of Nicotine Content in Mainstream Smoke

Abstract

The nicotine addiction problem is of great concern, particularly in adolescents. Notably, nicotine addiction drives humans to continue smoking. Notably, several diseases and disorders are caused by smoking. To date, various adsorbents have been proposed to develop a functionalization filter tip for reducing nicotine content in mainstream smoke. However, the nicotine adsorption efficiencies of most of the reported functionalization filter tips were not satisfactory, and their preparation process was complex and time-consuming. Herein, we demonstrate a highly active and adsorbing filter tip for cigarettes, fabricated by decorating polydopamine (PDA) on the surface of a commercial filter tip in situ. The PDA coating on the filter tip was obtained by the self-polymerization of dopamine (DA) within 16 h, which was quicker and easier than the preparation processes of other reported functionalized filter tips. Significantly, the PDA-decorated filter tip had a nicotine adsorption efficiency as high as ∼95%, which was much higher than most of the commercial filter tips.

A colorimetric sensor with dual-ratio and dual-mode for detection of nicotine in tobacco samples

“…Nicotine (NIC) is a volatile alkaloid containing pyridine and pyrrolidine rings. It is highly concentrated in tobacco leaves (Nicotiana genus, Solanaceae family) and cigarette smoke, 1 and widely used as a drug, pesticide and chemical. 2 Basic information on NIC can be found in Table S1 †.…”

Insight into the effects of different oxygen heteroatoms on nicotine adsorption from cigarette mainstream smoke

“…However, the yield of nicotine removal is still lower than the removal of other harmful compounds in mainstream smoke. Although there have been research works reporting the high nicotine removal capacity by using molecularly imprinted polymer 15 , oxidized mesoporous spherical carbon 16 , multiwalled carbon nanotubes (MWCNTs) based thin flexible membrane 17 , sepiolite granules 21 , polydopamine-decorated filter tip 22 , and nanocellulose-SiO 2 hybrid aerogels 23 , the key factors affecting effective nicotine adsorption are still unclear. The adsorption capacity depends not only on physical adsorption but also on chemical adsorption.…”
