“…Fibers coated with single-walled CNTs, which can be used for extracting phenols from aqueous solutions, have also been prepared by electrophoresis of a suspension of CNTs in dimethylformamide at a constant voltage of 40 V for 10 s [88]. Figure 7 shows different outcomes of EPD made CNT/ceramic nanocomposites.…”

EPD is a technique where charged particles in a stable colloidal suspension are moved through the liquid due to electric field and deposited on an oppositely charged conductive substrate, forming the intended material or device. EPD enables fabrication of a wide range of structures from traditional to advanced materials, from nanometric thin films to a fraction of 1 mm thick films, and from porous scaffolds to highly compact coatings. These structures include different compositions with complex shapes and structures which can be formed in a relatively short experimentation time by simple apparatus. This review presents the fundamentals, mechanisms, and characteristics of EPD along with its past and recent applications.

“…For new coating materials, high-porosity materials have attracted much attention recently because of their large specific surface areas and high extraction capacities resulting in significant improvement in sensitivity, such as carbon nanotubes [15], graphene [16,17] and metal-organic framework [7]. Mesoporous materials are considered the high-efficiency sorbents due to high specific surface area, controllable pore size, narrow pore size distribution, thermal and mechanical stability, which have various applications in chemical industry [18,19], environment [10,[18][19][20], medicine [21,22], adsorption and separation [23].…”

h i g h l i g h t sTwo novel mesoporous cellular foams were synthesized and used as SPME coating. Four SPME fibers were prepared by sol-gel technology and immobilized resin method. New coating had excellent extraction ability to seven brominated flame retardants. g r a p h i c a l a b s t r a c t a r t i c l e i n f o a b s t r a c tTwo kinds of mesoporous cellular foams (MCFs), including mesoporous silica materials (MCF-1) and phenyl modified mesoporous materials (Ph-MCF-1), were synthesized and for the first time used as fibercoating materials for solid-phase microextraction (SPME). By using stainless steel wire as the supporting core, four types of fibers were prepared by sol-gel method and immobilized by epoxy-resin method. To evaluate the performance of the home-made fibers for SPME, seven brominated flame retardants (BFRs), including tetrabromobisphenol A (TBBPA), tetrabromobisphenol S (TBBPS) and related compounds were selected as analytes. The main parameters that affect the extraction and desorption efficiencies, such as extraction temperature, extraction time, desorption time, stirring rate and ionic strength of samples were investigated and optimized. The optimized SPME coupled with high performance liquid chromatography (HPLC) was successfully applied to the determination of the seven BFRs in water samples. The linearity range was from 5.0 to 1000 g L −1 for each compound except TBBPS (from 1.0 to 1000 g L −1 ), with the correlation coefficients (r 2 ) ranging from 0.9993 to 0.9999. The limits of detection of the method were 0.4-0.9 g L −1 . The relative standard deviations varied from 1.2 to 5.1% (n = 5). The repeatability of fiber-to-fiber and batch-to-batch was 2.5-6.5% and 3.2-6.7%. The recoveries of the BFRs from aqueous samples were in the range between 86.5 and 103.6%. Compared with three commercial fibers (100 m PDMS, 85 m PA and 65 m PDMS/DVB), the MCFs-coated fiber showed about 3.5-fold higher extraction efficiency.
