“…Silane coupling agents (SCAs) constitute a special group of compounds that have the ability to form stable bonds between both organic and inorganic materials due to the presence of an alkoxysilyl group, which is prone to hydrolysis and linkage to mineral filler and organic function with an affinity to a polymer matrix [1] .

Synthesis of Bio‐Based Silane Coupling Agents by the Modification of Eugenol

et al. 2021

A simple method for the synthesis of new bio-based silane coupling agents (SCAs) with a terpene aromatic core by the functionalization of cheap, natural eugenol and its sulfur derivatives using the hydrosilylation of the C=C bonds with HSi(OEt) 3 , followed by nucleophilic substitution reactions of OH/SH groups is presented. The obtained alkoxysilanes possess different polymerreactive functionalities (alkenyl, epoxide, thiirane, thiocarbamoyl, thioester, thioether moieties). This new group of biogenic SCAs was fully characterized using 1 H, 13 C, 29 Si NMR, FT-IR, GC-MS, and HRMS or elemental analysis. Examples of their application as additives to tire rubbers and their influence on several factors are also discussed.

This account narrates polyolefin catalyst research at the Research Institute Interdisciplinary Research Center for Refining & Advanced Chemicals (IRCRAC). We particularly address catalyst performance and kinetic evaluation, novelty in supported metallocene catalysts, the apparently absurd residual catalyst structure and solid‐state electronic environment, illustration of supported metallocene catalyst active site distribution thru model and experiment, preparation of spheroidal MgCl2 support, and catalytic synthesis of energy‐saving drag reducing UHMW polymers using local petrochemical feedstock. Each area has been assessed from the product development perspective. Our PO catalyst research aligns with Saudi Arab's Vision 2030 National Strategic Plan (NSP). We also present a circular research concept which shows how product‐driven research with a commercial driving force can significantly advance fundamental PO catalyst chemistry to valuable applications for Saudi Arabia. Finally, we focus on establishing spinoffs using local raw materials. We highlight the role, to be played by researchers, R&D management, and potential investors, to develop the appropriate innovation diffusion culture. The critical need is to understand why an innovation will fail to be marketed. We particularly stress the importance of conducive sociology (environment), psychology (mental state), and mindset (preparedness to make and accept changes) that precede innovation and technology.

“…However, QP of small particle size tends to aggregate because of the high surface energy, and it has bad compatibility with a nonpolar polymer matrix because of its polarized surface, which results in an uneven distribution and weak interfacial adhesion [10,11]. Hence, surface treatment plays a vital role in improving the dispersion and compatibility of QP in a polymer matrix, as well as strengthening the mechanical properties of the polymer composites [12][13][14][15][16].…”

Application of Dual Silane Coupling Agent-Assisted Surface-Modified Quartz Powder in Epoxy Matrix for Performance Enhancement

Quartz powder (QP) is an inorganic filler that is expected to significantly enhance the dielectric and mechanical properties of epoxy (EP)-based composites applied in copper clad laminates and epoxy molding compounds for 5G applications. As is well-known, the performance of the QP–EP composites is directly correlated with the dispersion effect and the compatibility of QP with an EP matrix. Herein, we propose the surface modification method of QP by mixing SCAs of different alkyl chain lengths that contain amino and carbonyl groups. Different characterization methods (FTIR, TGA, XPS, SEM, contact angle measurement, viscosity, and mechanical properties) and molecular dynamics simulation were adopted to study its effect and mechanism. Through dual SCA modification, the viscosity of QP–EP composites was reduced by 11.70%, and the flexural and tensile strengths increased by 16.89% and 30.01%, respectively. In addition, it was revealed that the superiority of dual SCAs originated from the synergistic effect between APTES and SPIS, it was the electrostatic repulsion force between the amino groups of the two SCAs that caused a steric hindrance that activated the steric stabilization effect of SPIS, thus resulting in better dispersion and excellent compatibility. Meanwhile, the amino and carbonyl groups of the SCA interacted with the EP matrix via chemical bonds and hydrogen bonds, thus strengthening the interfacial adhesion between the QP and EP matrix and improving the mechanical performance of QP–EP composites. These results are evidence of the potential of the proposed approach, which is based on the synergistic compounding of SCA with different molecular structures, in powder industrial applications.
