Preparation and Characterization of Furan–Matrix Composites Blended with Modified Hollow Glass Microsphere

Abstract

<jats:p>In this study, a new class of thermal insulation composites was prepared by blending a modified hollow glass microsphere (HGM) with furan resin. The particle dispersion between the microparticles and resin matrix was improved using 3-methacryloxypropyltrimethoxy silane (KH-570). Furthermore, the structure and morphology of the modified HGM were characterised by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). In addition, the effects of the modified HGM on the thermal insulation, flame retardancy, and thermal properties of the composites were investigated. The thermal conductivity of the composites was lower than that of the native furan resin. The minimum thermal conductivity of the composites was 0.0274 W/m·K; the flame retardancy of the composites improved, and the limiting oxygen index become a maximum of 31.6%, reaching the refractory material level. Furthermore, the thermal analysis of the composites demonstrated enhanced thermal stability. This study demonstrates that the composite material exhibited good thermal insulation performance and flame retardancy and that it can be applied in the field of thermal insulation.</jats:p>

Recent advances in the development of green furan ring-containing polymeric materials based on renewable plant biomass

“…The mechanical properties, chemical and thermal stabilities, thermal conductivity and flame retardancy can be tuned by the addition of an organically modified woven glass fiber and talc filler 368 or organically modified glass microspheres. 369 Fully bio-based composites can be prepared by furan resin copolymerization with tung oil and bacterial cellulose fibers 370 or by compression forming with bamboo culms, resulting in construction materials with a remarkable compressive strength and excellent recovery characteristics. 371 The reinforcement of FAlc resin with the melamine foam leads to a composite suitable for use as a highly efficient absorbent for oil–water separation due to its excellent sorption capacities for various oils and organic solvents and high recycling abilities.…”

High Temperature Composites From Renewable Resources: A Perspective on Current Technological Challenges for the Manufacturing of Non-Oil Based High Char Yield Matrices and Carbon Fibers

“…Phenolic resins from biomasses have been indeed developed and studied extensively in recent decades, but the search for biobased alternative to standard phenolic in the specific sector of high charring matrices is still ongoing (Loganathan et al, 2021), even though it is predictable that the properties of resin synthesized from bioresources are lower than the raw material derived from oil (Ipakchi et al, 2020;Ma et al, 2020;Guo et al, 2021;Gruber et al, 2021). One example of nanofiller reinforced phenolic composites for ablative purposes comes from the paper of Ma et al, where the authors found that the addition of graphene oxide or graphitic carbon nitride (Figure 8C) (Ma et al, 2019) increased the char yield graphitization level during ablation, helping heat dissipation and thereby increasing the ablation resistance.…”

Effect of Hollow Glass Microspheres with Different Contents and Types on Properties of Polypropylene Composites

“…Currently, silane coupling agents containing both silicone functional groups and organic functional groups are widely used for such purposes. [12][13][14][15][16][17][18][19] Polypropylene (PP) is one of the most commonly used thermoplastic resins. Although pure PP can be used as thermal insulation and sound insulation materials, the mechanical properties are not sufficiently high for many applications.…”
