Lau, Mei-Tung;Li, Zikang;Sun, Zelin;Wong, Wai-Yeung research published 《 Synthesis, characterization and thermoelectric properties of new non-conjugated nitroxide radical-containing metallopolymers》, the research content is summarized as follows. In the last decade, there is an intense interest in the study of conjugated organic polymers for thermoelec. (TE) application. Non-conjugated polymers are usually considered as the insulators with no or extremely low elec. conductivity Nevertheless, non-conjugated radical polymers (NCRPs) are different from those polymers in which they can be widely applied in electronic technol., for example, as battery electrode materials, conductors in solid-state and memory devices, but they have not been used for the TE application. Here, three metal-containing NCRPs P1-P3 with different nitroxide radical moieties were synthesized and coated with single-walled carbon nanotubes (SWCNTs) to form various polymer composites. P2 exhibited the highest elec. conductivity of 1310.0 ± 3.92 S m-1 when the SWCNT content reached 60%. P3 had the highest Seebeck coefficient of 62.5 ± 0.40μV K-1 when the SWCNT ratio reached 90%. The highest power factor of 130.1 ± 1.61μW m-1 K-2 was achieved from the P3/SWCNT composite at the mass ratio of 90%. The results showed that the NCRPs could be one of the potential TE materials of further study.
2403-88-5, 2,2,6,6-Tetramethyl-4-piperidinol(TEMPO) is a useful research compound. Its molecular formula is C9H19NO and its molecular weight is 157.25 g/mol. The purity is usually 95%.
TEMPO is an intermediate used in the preparation of Piperidinyloxy free radical derivatives.
TEMPO is an organic compound that acts as a radical scavenger. It is stable in the presence of water and air and can be used for the inhibition of bacterial growth. TEMPO reacts with reactive intermediates to form non-reactive substances and terminate chain reactions. This process is optimal at temperatures between 0°C and 40°C and pH values between 3.5 and 7.5. TEMPO has been shown to inhibit the growth of bacteria by reacting with reactive molecules such as amines, chlorides, or low energy radicals in aqueous solution. TEMPO also has genotoxic activity that inhibits DNA synthesis in bacterial cells through oxidation of guanine residues on DNA molecules., Recommanded Product: 2,2,6,6-Tetramethyl-4-piperidinol
