“…This problem can be overcome by surface modification (SM) of the inorganic particles. The SM (also called pre-treatment, functionalization or coating of the surface) improves the interaction/bonding between nanoparticles and the host polymeric materials [147][148][149][150] and induces the formation of chemical and physical interactions with the polymer matrix, which could guarantee a durable chemical junction between two incompatible phases [151][152][153]. There are two ways to modify the surface of inorganic particles.…”

“…It was determined that in addition to homogeneous dispersion of fillers, strong interfacial adhesion between polymer matrix and filler is essentially crucial to obtain high-performance polymer/filler composites [15]. Surface modification of inorganic particles has attracted a great deal of attention because it produces excellent integration and improved interface between particles and polymer matrices [16][17][18][19]. For this reason determined limited enhancement in dynamic mechanical properties of PPS need to be a further investigation deal with the surface modification of VA particles.…”

The purpose of this study is to investigate the effect of surface modification of volcanic ash particles on dynamic mechanical properties of volcanic ash filled polyphenylene sulfide (PPS) composites. For this purpose volcanic ash particles were modified with 1, 3, 5 vol.% of 3-aminopropyltriethoxysilane (3-APTS) which has an organic functional group. All volcanic ash/PPS composite samples were prepared by using DSM Xplore 15 ml twin screw microcompounder and DSM Xplore 12 ml injection molding machines. The content of volcanic ash in composite samples was varied as 10 and 15 wt%. Volcanic ash filler dispersion and adhesion between volcanic ash particles and PPS matrix were examined by scanning electron microscopy. Dynamic mechanical properties such as storage modulus (E ) and glass transition temperature (Tg) were investigated by TA Instruments Q800 dynamic mechanical analyzer. During the experiments, the relation between silane coupling and dynamic mechanical properties was evaluated.

“…In addition, the quantum confinement effect leads to an enhancement of the absorption coefficient compared to that of the bulk materials [11]. Furthermore, surface modification of inorganic nanocrystals has attracted attention because it can produce excellent integration and can improve interfaces between nanocrystals and polymer matrix [12]. Thus, the incorporation of nanocrystals in the polymer matrix can induce the formation of hybrid excitons resulting from the mixing of Frenkel-Wannier excitons.…”

The optical properties of nanocomposite layers prepared by incorporation of tributylphosphine oxide (TBPO)-capped CdSe nanocrystals (NCs) in a P3HT polymer matrix are studied using different nanocrystal concentrations. Reflection spectra analyzed through Kim oscillator model lead to the determination of optical constants such as refractive index n, extinction coefficient k, dielectric permittivity e and absorption coefficient a.Using the common Cauchy, Drude-Lorentz, Tauc and single-effective-oscillator theoretical models, we have determined the values of static refractive index n s and permittivity e s , plasma frequency x p , carrier density N, optical band gap E g and oscillator and dispersion energies E 0 and E d , respectively. It is found that TBPO-capped CdSe NCs concentration affects the optoelectronic parameters of the nanocomposite thin films. Moreover, the disorder of this hybrid system is also studied by the determination of Urbach energy, which increases with TBPO-capped CdSe concentration.
