In this work, the novel natural rubber latex (NRL) mixing was approached. The mixing process was carried out by using n-hexane as the dispersed phase of silica aerogel which acted as thermal insulation filler prior to NRL mixing. The silica aerogel/NR composites were prepared with different silica aerogel contents of 20, 40, 60, 80, and 100 parts per hundred rubber (phr). The morphology of the 40 phr composite showed the NR macropore formation with silica aerogel intercalated layers. The optimal content of silica aerogels and n-hexane were the key to obtaining the NR macropore. The thermal insulation performance of silica aerogel/NR composites was investigated because of their porous structures. The thermal conductivity of the composites were lower than that of the neat NR sheet and decreased from 0.081 to 0.055 W m−1·K−1 with increasing silica aerogel content. The lower densities of the composites than that of the NR sheet were revealed noticeably. In addition, the silica aerogel/NR composites exhibited a higher heat retardant ability than that of the NR sheet, and the comparable glass transition temperatures (Tg) of the composites and the neat NR indicated the maintained flexibility at ambient temperature or higher, which can benefit various temperature applications. The overall results demonstrated that the silica aerogel/NR composites from the novel NRL mixing preparation could be a promising technique to develop the porous materials and be utilised as thermal insulation products and building constructions.

“…The thermal conductivity of TWF1c with the least weight and TW04 with the most weight are 0.0491 W/m•K and 0.06164 W/m•K, respectively. This tendency can be explained by the increase in the volume of the aerogel solid phase in the unit space, which leads to a decrease in the volume of internal air, thus increasing the thermal conductivity [29]. In addition, the increase of bers in the TWFs aerogel increases the heat transfer channels, which also causes the increasing of thermal conductivity.…”

In recent years, the treatment of textile waste has been attracted more and more attention around the world. The reuse of textile waste can contribute to the reduction of carbon emissions and the sustainable development of the economy. Herein, we proposed a facile and cost-effective approach to fabricating aerogel by using textile waste fibers as the matrix and polyvinyl alcohol (PVA) and glutaraldehyde (GA) as crosslinking agents. After coated with methyltrimethoxysilane (MTMS) via chemical vapor deposition, both the interior and exterior of the whole textile waste aerogels surface exhibit a super-hydrophobic property with a water contact angle of up to 136.9°. A comprehensive investigation of its structure, thermal performance and oil absorption capacity has been carried out for high-value applications such as building insulation and oil spill cleanup. The textile waste fibers aerogels have ultra-low density and high porosity, good thermal stability and outstanding heat insulation properties (K avg = 0.049–0.061 W/m·K). It has a competitive commercial application value that the maximum oil absorption value reaches 18.6 g/g.

“…Density and porosity value of foams were 0.019-0.046 g/cm 3 and more than 96%, respectively. These foams exhibited good heat insulation with low thermal conductivity (0.039-0.043 W/m K) due to the porous structure inside 49 . The produced cellulose foams have a low density (0.0554 g/cm 3 ), good thermal stability, and a high porosity (89.32%).…”

In this study, foaming-agent free novel polyvinyl acetate (PVAc) foams reinforced with bio polymers were manufactured through freeze-drying technique. The physical, morphological and antibacterial properties of foams which were reinforced with different ratio of zinc borate and water-soluble chitosan were investigated according to relevant standards. The PVAc foams showed low densities (0.12 g/cm 3 -0.21 g/cm 3 ) and high porosity rates (87.50% -79.05%). The results showed that although the foams have no antibacterial character against Escherichia Coli, they have antibacterial character against Staphylococcus Aureus bacteria. This study mainly focusses on physical and morphological properties of the foams. However, researchers also performed accelerated weathering tests to determine its usability in different industries. The effects of accelerated weathering on the surface of foams were investigated by measuring surface color. The highest color difference was determined 8.09. This foam can be used as a low-density packaging material and/or medical box with its promising physical and morphological properties with hazardous-chemical free structure.
