We'd strongly advise getting specialist advice from an expert or two in this area and proceeding with caution.Spray foam insulation is versatile and can be used to insulate the roof, loft, walls and floor, helping to retain warmth and reduce energy costs. However, the potential risks are likely to outweigh the rewards. Create the personalised portable working station you always dreamt to work more efficiently with the exact tool selection your business need. Marcano, D. C. Correction to improved synthesis of graphene oxide. ACS Nano 12(2), 2078–2078 (2018). Boukhvalov, D. W. Modeling of epitaxial grapheme functionalization. Nanotechnology 22, 20–25 (2011). We employ a host of reduction protocols to obtain rGO samples with different degrees of reduction 24, 60, 61. Specifically, thermal reduction was carried out at 300 °C for 10 minutes and the microwave reduction was carried out using a conventional microwave oven operated at 800 W for 2 s. The chemical reduction protocol employed the green reduction of GO using L-ascorbic acid as proposed by Abdolhosseinzadeh et al. 60. In Fig. 7(d), we show the I-V characteristics of drop-casted films for these rGO samples. For a comparison, the I-V characteristics of a drop-casted film (using identical dilution and drop volume) of commercially available graphene nanoplatelets (CAS 7782–42–5 from TCI) is shown in Fig. 7(d). The comparative Raman spectra for these different rGO samples is summarized in Fig. 7(e) along with the Raman spectra of graphene nanoplatelets. One can clearly observe that rGO samples with tunable conductance can be very conveniently made using high quality GO samples made using our method opening up possibility for a host of end applications. It is worth mentioning here that Abdolhosseinzadeh et al. 60 did not perform the electrical characterization of reduced films and the starting GO used by them was made using an extensively time consuming process to avoid any explosions. Furthermore, the GO samples reported by Abdolhosseinzadeh et al. 60 contained prominent amounts of Mn-based impurities. As can be observed from the inset in Fig. 6(a), we did not observe any signatures corresponding to Mn 2p 1/2 and 2p 3/2 peaks in the window 635–660 eV in the XPS measurements. For a comparison, one can look at the existence of distinct Mn 2p 1/2 and 2p 3/2 peaks in the range 635–660 eV of binding energies in Mn-containing samples (see Fig. 2(b) of Zhang et al. 80). An optical image of a piece of dried GO foam obtained after vacuum desiccation of the as grown GO sample can be seen as part of the schematic (see Fig. 7(a)). Such GO foam has tremendous potential for bio-medical 1, 2, 3, 4, 6, 7, 8, 10 and energy storage applications 21, 22, 28. Akin to the feasibility of scalability, the GO made using our method also has tremendous potential for environmental remediation applications 13, 14, 15.

Every home is different and, since it's hard to remove spray foam once it has been installed, we'd advise getting specialist advice from an expert before proceeding.

According to the Royal Institution of Chartered Surveyors, if a surveyor encounters spray foam insulation during their inspection, they may reduce the value of the property or request an independent specialist report. In some cases, spray foam insulation may even render a property un-mortgageable in the eyes of a lender.
