Preparation and performances of a novel intelligent humidity control composite material

Sepiolite-sulfur as a high-capacity, high-rate performance, and low-cost cathode material for lithium–sulfur batteries

“…The absorption peak at 3560 cm À1 in the IR spectrum is attributed to the crystalline water of sepiolite (based on Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC) data shown in Fig. S1 in the supplementary information, the crystalline water in sepiolite is decomposed between 160 C and 360 C, consistent with literature reports [32,33], and thus during our processing, these crystalline water is stable), bands in the range of 1200e400 cm À1 are characteristic of silicate, the absorption peaks at 1030 cm À1 and 469 cm À1 are ascribed to the SieO stretching and bending of sepiolite, and the peaks at 789 cm À1 and 681 cm À1 correspond to the SieOeSi stretching and vibration of sepiolite [29,34,35]. In addition, the chemical analysis of sepiolite powder was carried out using XRF and the main components are found to be SiO The morphology of sepiolite was further examined by SEM and TEM.…”

Development of mortars containing superabsorbent polymer

“…The indoor moisture variation might be modulated by suitable SAP-containing composite materials, since they are able to quickly respond to humidity changes [16]. For instance, SAP-containing mortars showed interesting moisture buffering values (MBVs), being classified as ''good or excellent'' according to the Nordtest protocol [17].…”

Polyacrylamide-based polyampholytes and their applications

“…As mentioned previously, inorganic additives as well as polymeric compounds can be used for wastewater treatment. The various types of flocculants widely used in the treatment of wastewater were reviewed recently (Yang et al 2011). However, it is nearly impracticable to remove heavy metals very well from wastewater directly by these current flocculants.…”
