“…For example, and HOSi(OSi) 3 (Q 3 , " = -103.96 ppm) can be observed [35]. In addition, the AMS particles display two more resonance peaks at " = -65.65 ppm, assigned to R-Si(OSi) 3 (T 3 ), and at " = -62.29 ppm, attributed to R-Si(OH)(OSi) 2 (T 2 ) [35]. These two peaks arise from the silicon atoms at different environments in the organosilane PAPTMS.…”

“…A Yanagimoto Co., Ltd. gas permeability analyzer (model GTR 10, Japan) was employed to perform oxygen/nitrogen gas permeation experiments. 3 solution were mixed and stirred for 10 min at room temperature. Simultaneously, a mixture of 5.2 g of TEOS and 1 g of PAPTMS was stirred in another container at room temperature.…”

“…Incorporating inorganic nanoparticles into organic polymers will improve the mechanical, thermal, optical and barrier properties. Commonly used inorganic additives include clay [1,2], SiO 2 [3][4][5], carbon nanotubes [6,7], and carbon nanofibers [8], among others. Polyaniline (PANI) is a potential material for commercial applications owing to its facile synthesis, relatively low cost, environmental stability, good processability, and unique optical, electrical and electrochemical properties [9,10].…”

Abstract.In this study, we compare the effects of aniline-modified mesoporous silica (AMS), raw silica (ARS) and nonmodified raw silica (NRS) particles on the physical properties of as-prepared polyaniline (PANI)-silica mesocomposites (PSM) and nanocomposites (PSN) and PANI-raw silica (PRSN) membranes. First, aniline-modified silica particles were synthesized by a conventional base-catalyzed sol-gel reaction of tetraethyl orthosilicate (TEOS) in the presence or absence of N-[3-(Trimethoxysilyl) propyl]aniline (PAPTMS). Subsequently, PSM, PSN and PRSN materials were prepared through in situ oxidation polymerization reaction of aniline monomer in the presence of AMS, ARS and NRS particles. It should be noted that all the properties of PSM membranes improved substantially from those of PSN and PRSN. For example, upon 3 wt% loading of AMS particles, 10, 25, 10, and 85% increases in thermal stability, mechanical strength, surface hydrophilicity and gas permeability were observed for PSM membranes, respectively, as well as more than 45% reduction in the thermal conductivity.

A new class of conductive composite materials, solvent-free ionically grafted nanoparticles, were modeled by coarse-grained molecular dynamics methods. The grafted oligomeric counterions were observed to migrate between different cores, contributing to the unique properties of the materials. We investigated the dynamics by analyzing the dependence on temperature and structural parameters of the transport properties (self-diffusion coefficients, viscosities and conductivities) and counterion migration kinetics. Temperature dependence of all properties follows the Arrhenius equation, but chain length and grafting density have distinct effects on different properties. In particular, structural effects on the diffusion coefficients are described by the Rouse model and the theory of nanoparticles diffusing in polymer solutions, viscosities are strongly influenced by clustering of cores, and conductivities are dominated by the motions of oligomeric counterions. We analyzed the migration kinetics of oligomeric counterions in a manner analogous to unimer exchange between micellar aggregates. The counterion migrations follow the "double-core" mechanism and are kinetically controlled by neighboring-core collisions.

“…To address the problems, ceramic fillers such as SiO 2 [12][13][14], Al 2 O 3 [15,16], TiO 2 [17,18] have been incorporated into polymer matrices to develop a new family of composite polymer electrolytes (CPE). It has been noticeable that the addition of ceramic fillers can offer improved ionic conductivity, safety, and in particular, electrolyte/ electrode compatibility [19][20][21]. In the CPE, it is reported that the ceramic particles can promote electrochemical properties by acting as a source of charge carriers when the particle surface is appropriately modified [22,23].…”

a b s t r a c tComposite polymer electrolytes (CPE) based on triethylene glycol diacetate-2-propenoic acid butyl ester (TEGDA-BA) incorporating Al 2 O 3 nanoparticles have been fabricated via in situ polymerization. The CPE have exhibited highly uniform morphology, excellent mechanical property (maximum stress up to $ 1.3 MPa), high ionic conductivity up to 3.92 Â 10 À 3 S cm À 1 at 25°C, coupled with very high electrochemical stability ( 45.0 V vs. Li/Li þ ). The Li | CPE|Li[Li 1/6 Ni 1/4 Mn 7/12 ]O 7/4 F 1/4 cells have demonstrated remarkably stable charge/discharge performance and great capacity retention in the potential range of 2.0-4.8 V. The unexpected growth of interface resistance has been retarded with the presence of Al 2 O 3 , indicating the enhancement of the interface stability. The results suggest that the CPE have demonstrated tremendous application potential in high-voltage lithium ion batteries.
