“…The OH group of the whiskers can interact with the silanol groups of the hydrolyzed γ‐MPS and CC will be introduced onto the surface of whiskers, which can induce free radical polymerization of MMA monomer. Consequently, PMMA is grafted and anchored on the surface of whiskers, and PMMA grafted on the whisker can prevent agglomeration and sedimentation of whiskers . In addition, PMMA is soluble in DCE solvent, thus the whiskers grafted by PMMA can homogeneously disperse in DCE solvent and form a stable colloidal dispersion.…”

In this study, calcium carbonate (CaCO3) whiskers were grafted with poly(methyl methacrylate) (PMMA) by in situ emulsion polymerization using γ‐methacryloxy propyl trimethoxyl silane (γ‐MPS) as a coupling agent, and the properties of resultant whisker were determined using Fourier transform infrared (FTIR) spectroscopy, energy dispersive spectroscopy (EDS), X‐ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). The results show that PMMA has been successfully grafted onto the surface of CaCO3 whiskers and the maximum grafting degree (Gd) is 3.75%. The scanning electron microscopy (SEM) micrographs of the tensile‐fractured surfaces show that modified CaCO3 whiskers have strong interfacial adhesion to the poly(vinyl chloride) (PVC) matrix. The tensile strength increases from 44.0 MPa for PVC composite with unmodified whisker to 49.5 MPa for that with grafted whisker. The dynamic mechanical analysis (DMA) and TGA results indicate that the composites reinforced by modified CaCO3 whiskers have much higher modulus, glass transition temperature, and better thermal stability than their counterparts reinforced by unmodified CaCO3 whiskers.

“…In fact, zêta potential determined the static electricity force among nano-SiO 2 particles and influenced greatly the character either agglomeration or dispersion among the nanoparticles [23][24][25]. When the nanoparticles of SiO 2 became close to the cathode, the repulsion force among the double-charge layers of nanoparticles and increased the possibility of conglobation among nanoparticles.…”

“…Compared with NHSG-TiN, the spectrum of M-NHSG-TiN has two weak absorption peaks at 2946 cm −1 and 2842 cm −1 , corresponding to the vibration absorption of -CH 3 and -CH 2 respectively [23]. Further, the absorption peaks at 1720 cm −1 and 1637 cm −1 correspond to C=O vibration adsorption and C=C vibration adsorption [24], respectively. And the -Si-O-C vibration absorption peak is located in the region of 1000-1200 cm −1 [25].…”

With the fast development of modern intelligent buildings, the demand for a comfortable environment and 'low carbon' technologies, for example, energy-saving buildings, becomes more intense. Thermal insulation coatings as one of the most promising routes to alleviate the energy consumption of buildings attract extensive attention in recent years. In this work, titanium nitridebased organic-inorganic composite films (TiN O/I films) were introduced as the thermal insulation coatings to window glass via blade coating method. Additionally, two different synthesis methods were adopted to prepare the inorganic TiN nanoparticle and its effect on the optical property of the coatings was studied detailedly via the ultraviolet-visible-near-infrared (UV-vis-IR) spectrophotometer and Fourier transform infrared spectrometer characterizations. In addition, the thermal insulation properties of the films were characterized by a system that simulates the natural environment. Various characterizations show that the synthesized TiN O/I films can not only pass through the visible light but also has high reflectance at the mid-infrared range, that is with the functions of solar control and low emission, well satisfying the requirements of the energy-saving coatings for window glass. These results demonstrated the good feasibility of TiN O/I films in thermal insulation coatings, and also provide a direction for the development of more novel thermal insulation materials with large-scale.
