| 4. | The sem micrographs of xerogel thin films show that the surface of the films is homogeneous , no cracks and holes are observed and it has a fiber - like microstructure Sem观察表明v _ 2o _ 5 - moo _ 3干凝胶薄膜是一种纤维状显微结构,且纳米复合薄膜表面均匀,无裂纹和孔洞。 |
| 5. | The major results were listed below : the forming processing of xos xerogel was studied . the results showed that it is useful to apply the oxygen top - blend technique to the fabrication of vaos xerogel by melt quenching 研究了氧气顶吹对v _ 2o _ 5干凝胶形成过程的影响,结果表明:氧气顶吹工艺运用于熔融淬冷法制备v _ 2o _ 5干凝胶是可行的。 |
| 6. | The synthesis of water - soluble pyrrole and poly ( trimethyl - ( 2 - pyrrol - l - yl - ethyl ) - ammonium iodide ) / vios nanocomposite was studied systemically . the vos xerogel was prepared by melt quenching method and the fabrication method was improved 本论文详细评述了聚合物层状无机化合物纳米复合材料的研究进展,介绍了有机-无机纳米复合材料的特点和应用前景。 |
| 7. | Peo can be completely intercalated into the interlayer of v2o5 xerogel in form of amorphous state at x = 0 . 5 , whereas partial peo can not be intercalated into v2os xerogel interlayer and exists outside of v2o5 xerogel interlayer in form of crystalline state at x = l , 2 当x为0 . 5时, peo的嵌入较完全,在层间以非晶态形式存在;当x = 1 、 2时,部分peo未能嵌入氧化物干凝胶层间而存在于其主体之外,以晶态形式存在。 |
| 8. | Peo can be completely intercalated into the interlayer of v2o5 - moo3 xerogel in form of amorphous state at x 1 , whereas partial peo can not be intercalated into v2o5 - moo3 xerogel interlayer and exists outside of v2o5 - moo3 xerogel interlayer in form of crystalline state at x = 2 当x约为1时, peo的嵌入较完全,在层间以非晶态形式存在;当x = 2时,部分peo未能嵌入氧化物干凝胶层间而存在于其主体之外,以晶态形式存在。 |
| 9. | The xps analyses show that there were two different chemical conditions of li + ions when li + ions were inserted into v2o5 - moo3 xerogel , corresponding to the li + ions in the interlayer and interstitial positions ( localized by the layers ) of v2o5 - moo3 lattice , respectively 当peo嵌入后,层间li ~ +离子含量大大增多, li ~ +离子以层间li ~ +离子(非水化)为主要存在形式,并且peo的嵌入削弱了li ~ +离子与周围环境的相互作用。 |
| 10. | During the temperature of 360410 , the weight lose was aboutl . 8 % of both sample a and sample b . the calculating result of n ( water molecular number ) was n = 1 . 59 ( sample a ) , n = 1 . 79 ( sample b ) respectively . li + ion storage properties in xos xerogel films were related to the content of v5 + ion and the situation number that li + ion were capable to hold 干凝胶的离子储存能力受到薄膜中vk离子的含量和理离子可占据的总位置数限制,热处理温度对理离子的储存性有一定的影响:低温时,由于凝胶薄膜中层间水的脱出,有利于注理量的提高;高温时,有v坍离子产生,不利于注理量的提高。 |
