Three types of nanocomposites, depending on how many dimensions of the dispersed particles are in the nanometer range can be distinguished [1]. Particles with three dimensions in the order of nanometers are typically isodimensional, such as spherical silica nanoparticles obtained by in situ sol-gel methods [2,3] or by polymerization promoted directly from their surface [3,4]. They also include semiconductor nanoclusters [5] and others [3]. Nanotubes or whiskers (with dimensions in the nanometer scale and the third forming a larger elongated structure), for example, carbon nanotubes [6] or cellulose whiskers [7,8], are extensively studied as reinforcing phases yielding materials with exceptional properties. The third type of nanocomposites is characterized by only one dimension in the nanometer range. In this case the material is present in the form of sheets of one to a few nanometers thick and hundreds to thousands nanometers long. This family of composites is referred to as polymer-layered crystal nanocomposites.Depending on the nature of the components used (layered structure, organic ions/polymer matrix) and the method of preparation, three main types of composites may be obtained when a layered structure is associated with a polymer [1].If the polymer is unable to intercalate between the layered sheets, a phase-separated composite is obtained, whose properties stay in the same range as traditional microcomposites. Beyond this classical family of composites, two types of nanocomposites can be dis...

“…iii) Region III (over 550 °C): this temperature region is characteristic for structural water and CaCO 3 decomposition [69][70][71][72][73][74][75][76]. Since the amount of structural water and CaCO 3 (which may formed during the synthesis of C-S-H and C-S-HPN materials) is very low, DTG peaks corresponding to the release of H 2 O, and CO 2 from CaCO 3 are very weak or insignificant.…”

“…• RT-250°C: this is the region of C-S-H decomposition [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53] due to loss of molecular water with DTA peaks at 71-134°C. In the case of C-S-HPN material, the decomposition temperature (T d )inthis region is variable depending on the synthesis and material compositions.…”

“…The shift of DTA peak to the higher temperature in C-S-HPN material compared to pure PVA and C-S-H is due to the improved thermal stability of C-S-HPN material. • Over 550°C: this temperature region is characteristic for structural water and CaCO 3 decomposition [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53].
