The microstructure, crystal phase and molecular structure were characterized by SEM, XRD and IR. Meanwhile, the thermal properties, energy properties and mechanical sensitivity of the composites were also studied. The ETN particle size is about 500nm, and few partial gel skeleton collapsed and contracted. No phase transformation of the ETN occurred before or after fabrication, and the molecular structures of the ETN, NC and GAP did not change. There is only one exothermic peak in the DSC traces and the peak temperature of nanocomposites are approximately 62°C, 24°C and 41°C earlier than raw ETN. The Isp, C*, Tc, Mc, and Qp increase with the weight percentage of ETN increasing, and the oxygen balance of three samples is still negative. The mechanical sensitivity are all lower than raw ETN. The energy performance and safety performance of samples are improved.","PeriodicalId":177601,"journal":{"name":"Journal of Advances in Nanomaterials","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127931864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and Energy-dispersive X-ray spectroscopy (EDX) techniques were used to determine the morphological and chemical properties, chemical structure and the elemental analysis of both layered double hydroxide nanosheets LDH-NS and alkali treated layered double hydroxide nanosheets (A-LDH). Moreover, the both samples LDHNS and A-LDH show a significantly catalytic behavior towards the degradation of crystal violet (CV) dye in the presence of H2O2 as assisting agent. However, the catalytic efficiency for both samples LDH-NS and A-LDH is highly reduced in the absence of the oxidizing agent (H2O2). The apparent rate constant of the catalytic degradation reaction was preformed from the first order kinetic model.

The substitute material is a thermoresponsive hydrogel, and the photocatalyst are uniformly dispersed tungsten trioxide nanoparticles. These nanocomposites confining poly(ethylene oxide)poly(propylene oxide)-poly(ethylene oxide) tri-block copolymer (EPE) molecules have packaged visible light driven isopolytungstate nano-buildings within the pores of copolymer fiber nets. The networks are provided (formed) by N-Isopropyl acrylamide (Nipam) and Acrylamide (AM). In wastewater solution, the Nipam-co-AM hydrogel is utilized to be a switchable and efficient filter for larger sized residue when subjected to temperature variation. By adding isopolytungstate nanoparticles as photocatalyst monomer, the small sized toxic organic materials can be effectively degraded. Such a hydrogel with distinct thermal and sunlight responsive properties can be produced as a functional material for wastewater dye degradation and large sized residue treatment of great significance in environmental friendly applications.","PeriodicalId":177601,"journal":{"name":"Journal of Advances in Nanomaterials","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128212592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
