Interconnected porous material of poly (glycidyl methacrylate) for selectively reducing phenol in cigarette smoke
Interconnected porous material of poly (glycidyl methacrylate) (PolyGMA) was synthesized for selectively reducing phenol in cigarette smoke. PolyGMA was characterized via Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM) and BET specific surface area analyzer. The material was applied in dual filter or spread on cigarette paper for testing its selectivity. The results showed that: 1) the material exhibited epoxy groups and interconnected porous in structure with the specific surface area of 119.5 m2/g and the average pore size of 17.3 nm. 2) Adding into dual filter showed better effect than did cigarette paper coating, phenol reduced by 28.3 % and the selective reduction rate of phenol reached 23.0 % comparing with the control. Meanwhile, the sensory quality of cigarette had no significant difference. This material provided an option for selectively reducing the phenol in cigarette smoke.
