“…It is generally true that surface properties of filler play a crucial part on the affinity of polymer and inorganic fillers, and there are various activation treatments applied to manipulate surface modification of inorganic materials during the past few decades including coupling agent modification, mechanical activation, thermal activation, surfactant modification, plasma treatment, and microwave activation. [20][21][22][23][24][25][26][27][28][29][30] Among these methods, coupling agents can change the surface wettability of materials without affecting the most properties, and it has been widely used in surface modification of inorganic matters due to easy availability and high efficiency, including silane coupling agents, titanate coupling agents, aluminate coupling agents, and rare-earth coupling agents. [20][21][22][31][32][33][34] With the excellent performance, titanate coupling agents are consumed popularly in surface treatments of numerous materials.…”

In this study, surface modification of coal gangue (CG) was performed with titanate coupling agent 201 (isopropyl tri(dioctylpyrophosphate) titanate), and the effects of surface modifier on mechanical properties and thermal stability of high‐density polyethylene filled with CG (HDPE/CG) and high‐density polyethylene filled with modified CG (HDPE/mCG) composites were investigated. The coupling agent was successfully grafted on CG surface through chemical reaction according to the analyses of Fourier transform infrared spectroscopy (FT‐IR) and X‐ray photoelectron spectroscopy (XPS), and the coupling agent can effectively enhance the hydrophobicity of surface that was verified by water contact angle beyond 90° of modified CG sample. With the introduction of coupling agent, some enhancements of tensile strength, flexural strength, and impact strength were observed in HDPE/mCG compared with HDPE/CG, due to the improved compatibility between mCG fillers and matrix. The increased storage modulus and decreased loss factor of HDPE/mCG composite further confirm the stronger interface adhesion after modification. Moreover, it is found that titanate coupling agent 201 can improve the thermal stability of HDPE/mCG composite to some extent.
