Synthesis and rheological investigation of self‐healable deferoxamine grafted alginate hydrogel 下载免费PDF全文

Deferoxamine grafted alginate (SA‐DFA) was successfully synthesized via amidation of sodium alginate with deferoxamine mesylate as determined by H‐NMR and elemental analysis. SA‐DFA with different graft yield was obtained by adjusting the ratio of sodium alginate and deferoxamine mesylate. It was found that aqueous solution of SA‐DFA could form hydrogel spontaneously due to hydrogen bonding interactions, which also endowed the SA‐DFA hydrogel with self‐healing capability. The healing efficiency of SA‐DFA hydrogels ranged from 53.64 to 90.16%. In addition, surface morphologies of SA‐DFA hydrogels before/after self‐healing process were demonstrated by SEM images. We anticipated that such self‐healable alginate hydrogel would be applied in the field of wound healing. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym. Phys. 2017 , 55, 856–865 相似文献

Abstract. A novel germanate compound, |[Ni(dien)2]3(H2O)3|[Ge7O13F5]2(designated JU‐85, dien = diethylenetriamine), was solvothermally synthesized. The structure of JU‐85 was determined by single‐crystal X‐ray diffraction and further characterized by powder X‐ray diffraction, inductively coupled plasma, infrared spectroscopy, elemental analysis, and thermogravimetric analysis. JU‐85 has dissymmetric chains constructed from diagonally linked Ge7 building units and various Ni(dien)22+ complexes formed in situ during the synthesis. Compared with its structural analogue, FJ‐6, JU‐85 contains less complex cations and different host‐guest assembly. Besides the diagonal linkage in JU‐85, other dissymmetric linkages of Ge7 building units were enumerated, which could be used as the stereogenic centers for the design of novel chiral germanate compounds. 相似文献

The syntheses and the structural characterization of the compounds [(mes)2Te–Te(I)mes], (PyH)[mesTeI3(I3)] (mes = mesityl = 2,4,6-trimethylphenyl; Py = pyridine), (PyH)3[dmephTeI2(I2)]2(I3) (dmeph = 2,6-dimethylphenyl), (PyH)2[RTeI4]2·(CH3)CO(CH3)·C6H5CH3 (R = p-tert-butylphenyl) and (PyH)2[PhTeI4]2 (Ph = phenyl) are presented. Some earlier analog preparations are compared and the influence of ortho substituents in the aryl group on the oxidation state of tellurium is discussed, as well as the observed conditions for the formation of poly-iodides chains. 相似文献
