In-situ constructing uniform polymer network for iron oxide microspheres: A novel approach to improve the cycling stability of the conversion electrodes through chemical interaction

AbstractBased on the unique temperature and oxygen profiles in a burning cigarette, a novel approach is proposed in this paper to use a single oxidant/catalyst in the cigarette filler for simultaneous removal of carbon monoxide (CO) and nitric oxide (NO) in mainstream smoke. A nanoparticle iron oxide is identified as a very active material for this application due to its multiple functions as a CO catalyst, as a CO oxidant, and in its reduced forms as a NO catalyst. The multiple functions of the nanoparticle iron oxide are characterized in a flow tube reactor and the working mechanisms of these multiple functions for CO and NO removal in a burning cigarette are explained. The effect of smoke condensate on the catalyst are examined and discussed. The advantage of in situ generation of the catalyst during the cigarette burning process is illustrated. The test results of nanoparticle iron oxide for CO and NO removal in cigarettes are presented.

AbstractThe novel approach for in situ preparation of polymer/TiO2 composites via low-temperature in-matrix crystallization of sol-gel prepared titania was developed and successfully applied. Rigid aromatic polyimide (PI) and flexible poly(ether-urethane)acrylate (PEUA) were used as polymer matrices and the templates for titania crystallization. Structure and morphology of prepared hybrids have been characterized by WAXD, FTIR and SEM. Chemical interaction between functional groups of the polymers and reactive inorganic component were studied. It was found that the rigid PI is more perspective matrix (instead of flexible PEUA) for carrying out the low-temperature crystallization of TiO2. Developed crystallization technique allowed to decrease the temperature of TiO2 crystallization from 350-500 °C to 250 °C (at atmosphere pressure) and to prepare functional crystalline TiO2-based polymer composites as perspective photoactive materials. Moreover, proposed approach gives also the possibility to obtain the polymer composites with enhanced compatibility between dispersed titania and continuous polymer phases.

Triple Shape Memory

The paper discusses the possibility of using in situ generated hybrid polymer-polymer nanocomposites as polymeric materials with triple shape memory, which, unlike conventional polymer blends with triple shape memory, are characterized by fully separated phase transition temperatures and strongest bonding between the polymer blends phase interfaces which are critical to the shape fixing and recovery. This was demonstrated using the three-component system polylactide/polybutylene adipateterephthalate/cellulose nanofibers (PLA/PBAT/CNFs). The role of in situ generated PBAT nanofibers and CNFs in the formation of efficient physical crosslinks at PLA-PBAT, PLA-CNF and PBAT-CNF interfaces and the effect of CNFs on the PBAT fibrillation and crystallization processes were elucidated. The in situ generated composites showed drastically higher values of strain recovery ratios, strain fixity ratios, faster recovery rate and better mechanical properties compared to the blend.
