“…The addition of ceramic particles, such as alumina [114], silica [126,137] and CuO [129], leads to an increase in conductivity. These ceramic particles can lead to decreased crystallization, but may also enhance conduction at the polymer-ceramic interface.…”

“…According to their report, double bond containing modifier was firstly attached on silica aerogel surface (surface modification) and the grafting through technique was applied to attach polystyrene on the surface of silica aerogel. Chen-Yang et al [40] have investigated the effect of silica aerogel on the properties of polyethylene oxidebased nanocomposites. Boday et al [41] have also prepared strong polycyanoacrylate/silica aerogel nanocomposites via chemical vapor deposition of cyanoacrylate monomers on amine-modified silica aerogels.…”

Hydrophilic silica aerogel nanoparticles' surface was functionalized with 3-(trimethoxysilyl)propyl methacrylate (MPS). Then, the resultant functionalized nanoparticles were used in grafting through copolymerization of styrene and butyl acrylate by simultaneous reverse and normal initiation technique for atom transfer radical copolymerization (SR&NI ATRP) to synthesize tailor-made random poly (styrene-co-butyl acrylate) nanocomposites with twofold chains. Successful surface modification of hydrophilic silica aerogel nanoparticles with MPS is demonstrated by Fourier transform infrared spectroscopy and thermogravimetric analysis (TG). Nitrogen adsorption/desorption isotherm is applied to examine surface area and structural characteristics of the synthesized silica aerogel nanoparticles. Evaluation of size distribution and morphological studies were also performed by scanning and transmission electron microscopy. Conversion and molecular weight determinations were carried out using gas and size exclusion chromatography, respectively. Addition of MPS-functionalized nanoparticles by 3 mass% results in a decrease in conversion from 71 to 46 %. Molecular weight (M n ) of the free poly (styrene-cobutyl acrylate) chains decreases by adding 3 mass% MPSfunctionalized silica aerogel nanoparticles; however, polydispersity index (PDI) value increases from 1.17 to 1.48. Although PDI values of the attached poly (styrene-cobutyl acrylate) chains are increased from 1.54 to 1.76, M n values reveal an increment by adding silica aerogel nanoparticles. 1 H NMR spectroscopy results indicate that the molar ration of each monomer in the copolymer chains is approximately similar to the initial selected mole ratio of the monomers. Increasing thermal stability of the nanocomposites is demonstrated by TG. Differential scanning calorimetry also shows a decrease in glass transition temperature by increasing modified silica aerogel nanoparticles.

“…[12][13] Many kinds of silica nanoparticles have been used to synthesize polymer nanocomposites via different polymerization systems. [14] Although some research works have been done on the properties of aerogel/polymer nanocomposites, [15][16][17] there is no study on the effect of aerogel particles on the kinetics of polymerization and physical properties of nanocomposites. In this work, free radical and RAFT polymerizations of styrene, including different amounts of nanoporous particles (silica aerogel), were investigated.…”

Nanoporous silica aerogel particles were synthesized via sol-gel process and modified with a hydrophobic surfactant. Batch polymerizations of styrene in presence of silica aerogel particles were studied via free radical and reversible addition-fragmentation chain transfer (RAFT) polymerizations. Monomer conversion, molecular weight, and polydispersity index of each system were monitored during polymerization to investigate the reaction kinetics. According to results, in both systems, the presence of silica aerogel particles has a sensible influence on polymerization kinetic and adding aerogels results in decreased polymerization rate, conversion, and molecular weight. Moreover, the prepared samples were characterized by Fourier transform infrared spectroscopy. Also, thermal gravimetric analysis (TGA) and differential scanning calorimetric techniques was used to observe the effect of aerogel particles on thermal properties of synthesized nanocomposites. According to TGA depiction, in free radical samples, one-stage degradation, related to random chain scission, is observed while degradation of RAFT-prepared nanocomposites occurred in two steps due to the decomposition of RAFT moieties and random chain scission.
