“…The group of Gungor reports the same conclusion using close systems [4,22]. Another example, reported by Wouters et al [24], concerns a system based on acrylate, polyurethane resin, MEMO and TEOS. First, the authors studied the silica content effect.…”

“…These precursors, which have to be thermally or photo-chemically cured leads to an organic network, tangled up to the inorganic one. Close to this approach, it is also reported that the addition of pure organic monomers to the network former performs a double reticulation and creates a convolution of both O/I networks [4,10,[22][23][24][25]. In any case, sol-gel process mastery is primordial to prepare a stable sol, able to be deposited and reticulated in a three dimensions O/I hybrid network.…”

Organic/inorganic hybrid coatings prepared via the sol-gel process have received lot of interests during the early twenty-first century. Devices obtained thanks to this low-temperature route display a large panel of bulk and surface properties that can be modulated according to the target. Moreover, this versatility enables to offer solutions in various domains and industrial applications such as microelectronics, optic, aeronautic, automotive, health. When the aimed application required polymer as substrate, the use of sol-gel process takes its full interest as soft chemistry. This review is dedicated to mechanical properties improvement of a common polymer substrate, e.g., polycarbonate, when a transparent sol-gel coating recovered it. Graphical Abstract

“…However, because silicon dioxide is difficult to react because of its stable chemical properties, the silica precursor TEOS was used as the raw material in the modification of PLFM by the products of hydrolysis in an acidic environment (Corradini et al 1999). Using sol-gel technology (Brinker et al 1984;Schmidt et al 1984;Wu et al 2006), a PLCFM was prepared by means of combining organic materials with inorganic material through a simple process (Wouters et al 2004;de Oliveira et al 2008). The PLCFM with the excellent performance of organic materials and inorganic materials, such as wear resistance, heat resistance, and so on.…”

This study investigates methods for improving the heat resistance of polyvinyl alcohol/alkali lignin foam material (PLFM). Tetraethoxysilane (TEOS) was used as a precursor to prepare PLCFM by a sol-gel method. The PLCFM, prepared with different levels of TEOS, was characterized by Fourier Transform Infrared spectrometry (FTIR), Differential Scanning Calorimetry (DSC), and Thermogravimetric Analysis (TGA). The results indicated that the addition of silica notably improved the heat resistance properties and the initial decomposition temperature of the foam and exhibited good biocompatibility with the polyvinyl alcohol (PVOH) and alkali lignin. The melting temperature of the PLCFM also increased significantly. It reached 268 °C when the silica content was 10%, which was 110 °C higher than that of PLFM. The mechanical properties were also improved to 27.42 MPa.

“…Usually, most organic-inorganic hybrid materials are thermally cured [3][4][5], but some of them are cured by UV light yet [6][7][8][9][10][11][12]. This class of materials are very promising in the UV cured coating field because it combines the advantages of traditional hybrid materials and UV-curing technique, mainly including highspeed process, lower energy consumption as well as the curing process occurs at ambient temperature, lower process costs, high chemical stability of materials and lower VOCs (volatile organic compounds) of UV-curing technique [13,14], and the improvement of thermal and mechanical properties etc., due to micro-scale homogeneous network of the organic-inorganic hybrid material [1,15].…”

A series of silica sols modified by c-methacryloxypropyltrimethoxysilane (MPS) were synthesized by the acid-catalyzed sol-gel method, and then the solvent in these sols were extracted under several vacuum distillation conditions. The stability of the sol after the distillation can be improved by means of increasing the dosage of MPS and incorporating reactive diluent TPGDA into the sol as new dispersion medium. Optimized samples have maintained stable for over 180 days. The sol dispersions and UV-curable organic compounds were mixed to form the hybrid coatings for fire protection. Effects of the distillation treatment and the cosolvent anhydrous ethanol added into the reaction solution on thermal and combustion performances and physical properties of the hybrid coatings were studied by thermogravimetric analysis, microscale combustion calorimeter, limit oxygen index test and UL-94 horizontal test, etc. The results showed that the distillation treatment for the sol was necessary to improve thermal performance and physical properties of the hybrid coatings. In addition, in the flammability experiment, hybrid coatings showed a quick and efficient protection of the substrate.
