“…As seen, the apparent density of MBPFs first decreased and then rose with the increase of MMT addition rate, showing a minimum at 4 wt % MMT addition rate. Similar results of the reduction of foam density at lower loadings of MMT were also reported in other literature [49,50,51], and this trend can be explained by the opposing effect of MMT addition on nucleation and cell growth, which was also reported in Madaleno’s research [47]. A similar trend is shown between pulverization rate and apparent density.…”

Introducing bio-oil into phenolic foam (PF) can effectively improve the toughness of PF, but its flame retardant performance will be adversely affected and show a decrease. To offset the decrease in flame retardant performance, montmorillonite (MMT) can be added as a promising alternative to enhance the flame resistance of foams. The present work reported the effects of MMT on the chemical structure, morphological property, mechanical performance, flame resistance, and thermal stability of bio-oil phenolic foam (BPF). The Fourier transform infrared spectroscopy (FT-IR) result showed that the –OH group peaks shifted to a lower frequency after adding MMT, indicating strong hydrogen bonding between MMT and bio-oil phenolic resin (BPR) molecular chains. Additionally, when a small content of MMT (2–4 wt %) was added in the foamed composites, the microcellular structures of bio-oil phenolic foam modified by MMT (MBPFs) were more uniform and compact than that of BPF. As a result, the best performance of MBPF was obtained with the addition of 4 wt % MMT, where compressive strength and limited oxygen index (LOI) increased by 31.0% and 33.2%, respectively, and the pulverization ratio decreased by 40.6% in comparison to BPF. These tests proved that MMT can blend well with bio-oil to effectively improve the flame resistance of PF while enhancing toughness.

“…But when preparing thermal insulation materials by filling polymer matrix with hollow structured microspheres, it is necessary to continuously increase the content of hollow structured microspheres in the matrix to achieve low thermal conductivity of the composite material, which will lead to increasing viscosity of the composite system and eventually loss of processability. Some literature research [2,3] shows that foamed thermal insulation materials have excellent thermal insulation performance and thermal conductivity comparable to high quality inorganic aerogel materials due to the presence of a large amount of thermal insulating gas inside and the inorganic shell structure without hollow microspheres, but the structural strength of purely foamed thermal insulation materials is low. In summary, it is very important to carry out research on hollow microsphere filling and chemical foaming synergistic preparation of efficient thermal insulation and protective materials.…”

In this paper, three different functional phases of thermal insulation, hollow ceramic microspheres (HCM), hollow silica microspheres (HSM) and hydroxy silicone oil blowing agent (OH-3#)were selected, and a flexible and efficient thermal insulation composite with low thermal conductivity and high thermal structural strength was designed and prepared using the synergistic effect between the three. The results show that the thermal stability and mechanical performance of composites were significantly enforced.

“…We previously investigated the effects of two kinds of modified montmorillonite on the thermal stability and thermal insulation performance of SIF. 22 We also explored the effects of hollow microspheres on the thermal insulation of SIF. 23 The inorganic particles acted as the nuclear agent and offered a large number of nucleation sites, which was favorable in the formation of a uniform cell morphology.…”
