“…However, for economical propose, a facile, effective, low-cost technique without complex equipment to synthesise the hybrid composite is necessary. In this regard, microwave-assisted technique using microwave irradiation as an energy source has been extensively used for the synthesis of wide range of desired materials including nanoparticles, [15] porous materials [16] and nanocomposites. [17] Moreover, microwave can provide significant advantages over conventional heating such as non-contact, instantaneous and rapid heating rate resulting in the reduction of reaction time and uniform heat transfer.…”

Zinc oxide and multi-walled carbon nanotube (ZnO/MWCNT) hybrid nanocomposites were synthesised by microwave-assisted method using the mixed solution of zinc acetate dehydrate (Zn(CH 3 COO) 2 Á2H 2 O) and treated MWCNTs. The syntheses were carried out at various microwave irradiation powers. The characterisation of the as-synthesised nanocomposites was conducted by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results revealed that the composites were composed of two phases of MWCNTs and hexagonal wurzite ZnO. The SEM results showed that the ZnO nanoparticles were well decorated on the surface of MWCNTs. The amount of ZnO nanoparticles and their size increased with increasing irradiation power. Thick-film sensors were fabricated onto interdigitated conducting electrodes using as-synthesised hybrid composites as sensing materials. The alcohol-sensing behaviour of the hybrid composite films was investigated. The results indicated that the irradiation power had significant influence on the sensing response of the sensors toward alcohol. The sensor fabricated from the composite synthesised at higher irradiation power exhibited an enhanced alcohol-sensing performance.

“…Special interest today is focused on composite gel polymer electrolyte systems having high ionic conductivity at ambient temperatures, since they may find unique applications, for example in rechargeable lithium batteries, separators, and fuel cells. Polyacrylonitrile (PAN) [1], poly(vinylidene fluoride) (PVDF) [2][3][4], poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) [5,6] and poly(methyl methacrylate) (PMMA) [7][8][9] are the most common host polymers used for preparing gel electrolytes. Ceramic fillers such as SiO 2 [10], Al 2 O 3 [11], TiO 2 [12] and BaTiO 3 [13] have been incorporated along with the host polymer in order to obtain composite polymer electrolytes with improved electrical and mechanical properties.…”

In this paper, the single ionic conductor SiO 2 (Li ? ) was first synthesized from Tetraethylorthosilicate and c-(2,3-epoxypropoxy) propyltrimethoxysilane (KH560) by sol-gel hydrolysis and then neutralized by lithium hydroxide in methanol. The poly(vinylidene fluoride) based composite microporous gel polymer electrolytes (CMGPEs) doped with SiO 2 (Li ? ) was prepared by phase inversion method and the desirable CMGPEs was obtained after being activated in liquid electrolyte. The physicochemical properties of the CMGPEs were characterized by FT-IR, DSC, XRD, TG, stress-strain response and electrochemical measurements. It was found that with the addition of SiO 2 (Li ? ), the degree of crystallization of microporous polymer membrane was decreased while its porosity increased, which could promote the absorption and gelation of liquid electrolyte. In addition, due to vast amount of Li ? ions in the SiO 2 (Li ? ), it would promote ionic conductivity at room temperature for the CMGPEs. When the content of SiO 2 (Li ? ) reached 5 %wt, the ionic conductivity of the CMGPEs could reach 10 -2 S/cm order of magnitude at room temperature and the reciprocal temperature dependence of ionic conductivity of as-prepared CMGPEs follow arrhenius equation, in addition, its electrochemical stability window could reach 5.2 V.

“…The porous membrane prepared at 140 • C cannot be used due to very bad shrinkage. The reason can be ascribed to that the temperature of 140 • C is very close to the crystal fusion temperature of P(VDF-HFP) [31]. The mechanical strength was spoiled or destroyed during the microwave assisted effervescent disintegrable reaction.…”

“…In our previous work, this reaction has been firstly introduced to prepare porous polymer membrane and the membrane was used as the matrix of the gelled polymer electrolyte for lithium ion batteries, which shows high ionic conductivity at room temperature [31]. It is well known that the microstructure of the porous polymer membranes is the most important factor which directly affects the performance for the practical applications.…”
