“…Many reports on the preparation of metal oxide nanostructures by using this rapid method have been published. [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] It is widely known that zinc oxide (ZnO) is an important wide-bandgap II-VI semiconducting material and is widely used in the optoelectronics field. The application of the microwave-assisted ionic-liquid method in the synthesis of ZnO nanostructures was first carried out in our previous study.…”

“…It was found that the ionic liquids acted as both the microwave absorber and assistant stabilizer in the reaction, and could be recovered and reused in successive reactions many times. More recently, the microwave-assisted synthesis of silica nanoparticles with imidazolium groups was reported by Okada et al [34] A series of modified nanoparticles with various kinds of counter anions was prepared, and their abilities of being heated under microwave irradiation were compared. Experimental results indicated that the heating effect was not observed in hexane and chloroform, only in water, which implies that silica nanoparticles with imidazolium groups can directly absorb the microwave and work as a heat source.…”

In recent years, the microwave-assisted ionic-liquid method has been accepted as a promising methodology for the preparation of nanomaterials and cellulose-based nanocomposites. Applications of this method in the preparation of cellulose-based nanocomposites comply with the major principles of green chemistry, that is, they use an environmentally friendly method in environmentally preferable solvents to make use of renewable materials. This minireview focuses on the recent development of the synthesis of nanomaterials and cellulose-based nanocomposites by means of the microwave-assisted ionic-liquid method. We first discuss the preparation of nanomaterials including noble metals, metal oxides, complex metal oxides, metal sulfides, and other nanomaterials by means of this method. Then we provide an overview of the synthesis of cellulose-based nanocomposites by using this method. The emphasis is on the synthesis, microstructure, and properties of nanostructured materials obtained through this methodology. Our recent research on nanomaterials and cellulose-based nanocomposites by this rapid method is summarized. In addition, the formation mechanisms involved in the microwave-assisted ionic-liquid synthesis of nanostructured materials are discussed briefly. Finally, the future perspectives of this methodology in the synthesis of nanostructured materials are proposed.

In this study we developed hydrogel-based hybrid materials with gold nanoparticles that have tunable optical properties under light irradiation. Attaining the stimuli-responsive dynamic changes in the solid material from the optical properties of the gold nanoparticles depended on the interparticle distance, and we designed hydrogel-based organic-inorganic hybrids with gold nanoparticles. Homogeneously dispersed states of the modified gold nanoparticles were achieved in the hydrogel with the interaction of the imidazolium units tethered to both the nanoparticle surfaces and the side chains of the networks. Initially, we found that the absorption properties could be changed by swelling and shrinking the hydrogels. Next, by using the photoresponsive mono-carboxylate linker, we induced the photo-triggered modulation of the absorption properties of the hydrogels. These results can be explained by a change in the interparticle distance within the hydrogel matrix.

“…36,37 The microwaveassisted local heating leads to researches on media in organic reaction and nanoparticle coated ILs. [38][39][40] Herein, we focused on the microwave-assisted heating of ILs and microwave-responsive "ondemand-peeling" adhesives. When the size of adhered specimen is large, heating the whole specimen is difficult, whereas the selective local heating in microwave oven can limit the heated region of the adhesives.…”

We prepared microwave-responsive "on-demand-peeling" adhesives by only mixing secondgeneration acrylic adhesives with ionic liquids. Rapid responsibility (<30 s for adhesives failure) toward microwave irradiation was achieved using microwave oven. This "on-demand-peeling" was attributed to local heating of the ionic liquid in the adhesive by microwave irradiation. In addition, the adhesive strength was not influenced by ionic liquid additives without microwave irradiation. We revealed that the local heating and the plasticizing effect of ionic liquid resulted in the "on-demand-peeling". Our preparation method of the microwave-responsive adhesives were simple, conventional and attractive in the fundamental and industrial fields.
