22:T516,ABSTRACT In this article, thermoplastic polyurethane (TPU)/attapulgite (AT) nanocomposites were prepared by solution blending. The interaction between AT and TPU was investigated by Fourier transform infrared (FTIR) and dynamic mechanical analysis (DMA). The carbonyl stretching region (1680–1760 cm −1 ) of infrared spectra was studied to investigate the difference of the hydrogen bonding degree of the samples. The degree of hydrogen‐bonded carbonyl groups of the samples were found to be increased with increasing AT content and decreased with increasing temperature. The equilibrium between free and hydrogen‐bonded carbonyl groups was discussed. The values of dissociation enthalpy of the hydrogen‐bonded carbonyl groups increased with increasing AT content. Quantitative evaluations of the interaction between AT and TPU was conducted by analyzing the physical cross‐links density of the samples. The results indicated that the physical cross‐links density of the samples increased with increasing AT content. The results of tensile tests showed that with increasing AT content, the mechanical properties of the samples increased, which confirmed that strong interaction was formed between AT and TPU matrix. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016 , 133 , 43069.23:T501,The aggregation and the rapid restructuring of the photoinduced electron-hole pairs restructuring in the process of photoelectric response remains a great challenge. In this study, a kind of Multi-walled carbon nanotubes loaded Alpha-Fe₂O₃ (CNTs/α-Fe₂O₃) heterostructure composite is successfully prepared via the one-step method. Due to the synergistic effect in the as-prepared CNTs/α-Fe₂O₃, the defect sites and oxygen-containing functional groups of CNTs can dramatically improve the interface charge separation efficiency and prevent the aggregation of α-Fe₂O₃. The improved photocurrent and enhanced hole-electron separation rate in the CNTs/α-Fe₂O₃ is obtained, and the narrower band gap is measured to be 2.8 ev with intensive visible-light absorption performance. Thus, the CNTs/α-Fe₂O₃ composite serves as an excellent visible light photocatalyst and exhibits an outstanding photocatalytic activity for the cationic dye degradation of rhodamine B (RhB). This research supplies a fresh application area forα-Fe₂O₃ photocatalyst and initiates a new approach for design of high efficiency photocatalytic materials.
