用热失重法确定水合粘土水分含量及存在形式

文章以蒙脱土为例，采用热失重法定性定量确定了水合粘土中结合水类型、界限及其相对含量，并与等温吸附法结果进行了对比。结果表明，用该方法得到的水合蒙脱土中各种水分的相对含量及总含水量与等温吸附实验结果相一致。热失重（25~250 ℃）分析结果表明，水合蒙脱土中水分子主要存在自由水、松散吸附结合水、紧密吸附水（强吸附结合水）3种状态，分别对应于25~75 ℃、75~120 ℃、120~230 ℃区间里的失水。从热失重（25~250 ℃）规律来看，仍存在两个明显的转折点p/ps=0.9、0.98，它们为粘土-水体系的两个特征湿度，前者为粘土表面强结合水与松散结合水（渗透结合水）之间的界限，后者为松散结合水与自由水之间的界限，这验证了等温吸附法确定的两个特征湿度及对粘土表面结合水界限划分的正确性。     

New nanocomposite materials based on polymerization of [oligo(oxyethylene) methacrylates] in the presence of montmorillonite clay

Intercalation of poly[oligo(oxyethylene) methacrylates] onto sodium montmorillonite (MMT) clay has been investigated. A polymer–clay hybrid has been synthesized through intercalation of the monomer followed by its solution free‐radical polymerization. Eight polymer–clay hybrids were prepared using different weight ratios of clay, different oligo(oxyethylene) lengths and different proportions of crosslinker. Evidence of the development of nanostructures is obtained from scanning electron microscopy, and wide‐angle X‐ray diffraction studies support these results which show disappearance of the peak characteristic to d₀₀₁ spacing. In this hybrid MMT is dispersed homogeneously in the polymer matrix. © 2003 Society of Chemical Industry

Quantification of the layer dispersion degree in polymer layered silicate nanocomposites by transmission electron microscopy

As the performance of polymer layered silicate nanocomposites strongly depends on their interior layer dispersion, quantification of the layer dispersion degree is needed. In this work, a new methodology was developed to determine the dispersion parameter D_0.1, based on the measurement of the free-path spacing distance between the single clay sheets from the transmission electron microscopy (TEM) images. Several examples of exfoliated, intercalated, and immiscible composites were studied. It was found that the exfoliated composites had D_0.1 over 8%, while that of intercalated composites were between 4 and 8%. In the case of intercalation, a high frequency peak appeared at a short spacing distance in the histogram, which was a characteristic of the intercalation, distinct from the exfoliation. The main utility of this TEM methodology is for the quantification of exfoliated or intercalated samples with small number of layers with stacks. The dispersion parameter D_0.1 below 4% was suggested to classify as immiscible. A unique advantage of the TEM measurement is that the dispersion degree of different fillers can be counted individually.
