Nano (Fe)MIL-101 particles were grafted on the short carbon fibers (SCFs) by in situ growth method to prepare (Fe)MIL-101@SCFs. The flame-retarded composites of epoxy resin (EP) were fabricated with combination of (Fe)MIL-101@SCFs and ammonium polyphosphate (APP). The composites showed good flame retardancy, smoke suppression, and mechanical properties simultaneously. The main heat release rate peak of the flame-retarded composites was reduced and delayed evidently in comparison with pristine EP. The high amount of residual char with coherent and dense structure was formed owing to the catalytic char formation of (Fe)MIL-101 as well as the strengthening action of SCF. The improvement in mechanical properties of the flame-retarded composite was due to the reinforcement effects of (Fe)MIL-101@SCFs and its action of interfacial adjustment. This research solved the contradiction between the flame retardancy and mechanical properties of EP, and proposed a new method to prepare the mechanically reinforced and flame retardant EP. 相似文献
The main objective of this study is to understand the sensing origin of anatase TiO2 and provide an insight into why gas sensitivity of anatase TiO2 is not so excellent.
The transfer mechanism of an amphoteric rhodamine, sulforhodamine 101 (SR101), across the polarized water/1,2-dichloroethane
(DCE) interface was investigated using cyclic voltammetry, differential voltfluorometry and potential-modulated fluorescence
(PMF) spectroscopy. The voltammetric response for the ion transfer of SR101 monoanion from water to DCE was observed as the
diffusion-controlled transfer process. An unusual voltammetric response was found at 0.15 V more negative than the formal
transfer potential of SR101−
in the cyclic voltammogram and voltfluorogram. The frequency dependence of the PMF responses confirmed the presence of the
adsorption processes at negative potentials. In addition, a further transient adsorption step was uncovered at The interfacial mechanism of SR101 is discussed by comparing the results obtained from each technique. 相似文献
