“…Thus, the template method has been employed to fabricate various carbon foams using various carbon precursors for several potential applications [36][37][38][39][40]. The carbon foam based composites derived from the PU template method have been already demonstrated as a promising potential material for insulation, sorption, catalysis, purification and separation of oil and water [41,42]. To the best of our knowledge, the conventional methods fail to produce carbon foams with well-developed porosity and high thermal conductivity via template method using a simple preparation approach.…”

“…There is great interest in the development of new inexpensive precursor materials from renewable resources that produce [9]. Besides, template method [1], emulsion method [16], and ultrasound-assisted air bubbling strategy [17] have also been suggested. Chen et al [18] have prepared elastic carbon foam via direct carbonization of melamine foam for flexible electrodes and organic chemical absorption.…”

“…Carbon foams are new solid foams with many novel features, such as low cost, exceptionally high void volume, low specific weight, very high resistance to temperatures in non-oxidizing environments, good energy absorption, and high thermal conductivity or insulation as desired [1]. They have attracted much attention as their wide potential applications in the areas of aerospace, military, offshore, power production, and other commercial industries [2].…”

Carbon foams have attracted much attention since they were first developed in 1960s. Most of the reported carbon foams are of thick cell walls, which do not make effective use of the carbon skeleton in application. Herein, we present a biomass-derived carbon foam with nano-thickness carbonaceous walls. Different from the conventional oven heating process, the carbon foam was prepared with the assistance of microwave irradiation within only a few minutes. The prepared carbon foam has reticular morphology. The meshes of the network are in the dimensions ranging from about 10-50 lm and connected by thin carbonaceous walls with thickness of about 25 nm. The carbon foam has narrowly distributed slit mesopores around 2-4 nm. Active groups like hydroxyl, carbonyl, and epoxy groups are detected in its structure. It has potential to be applied as electrochemical material or catalyst support.

“…[3] In the first method graphene foams (GFs) are formed using either freeze-drying of graphene oxide (GO), employing a self-assembly chemical process to construct the reduced graphene oxide (rGO) structures in 3D or dip-coating a template. [14][15][16][17] While the latter method produces high quality porous graphene structures, the former is more facile and scalable. [8][9][10][11][12][13] These two methods produce GF with entirely different electrical, thermal, morphological, and mechanical properties with different levels of scalability.…”

We are reporting the formation of free-standing graphene foam (GF) via a novel two-step process, in which a polyurethane (PU) foam is first dip-coated with graphene oxide (GO) and subsequently the dried GO-coated-PU is heated in nitrogen atmosphere at 1000 C. During the pyrolysis of the GO-coated-PU, GO is reduced to GF whereas PU is simultaneously decomposed and released completely as volatiles in a step wise mass-loss mechanism. Morphology of the formed GF conforms to that of the pure PU foam as indicated by the scanning electronic micrographs. Polydimethylsiloxane (PDMS) was successfully infiltrated inside the GF to form flexible and stretch-able conductors. The GF-PDMS composite was tested for it's pressure and strain sensing capabilities. It is shown that a 30% compressive strain changes resistance of the GF-PDMS composite to about 800% of it's original value. Since density of the formed GF is tunable, therefore, the pressure/strain sensivity of the GF-PDMS composite is also tunable.
