Polyurea is an isocyanate derivative, and comprises the basis for a well-established class of
polymeric aerogels. Polyurea aerogels are prepared either via reaction of multifunctional …

An overview of the synthesis conditions and mechanisms for the fabrication of different types
of carbon aerogels, as well as the structural and functional properties of these materials, is …

Kistler, in his original definition, stated that aerogels are obtained from gels in which the pore
liquid is replaced by air with moderate shrinkage of the matrix. However, aerogels have …

We report the heat-transfer characteristics of polystyrene (PS)/multi-walled carbon nanotube
(MWCNT) nanocomposite foams with a large expansion ratio (18-fold) and a microcellular …

A large array of easily available small-molecule (as opposed to industrial oligomeric)
triisocyanates and aromatic polyols render polyurethanes a suitable model system for a …

Vacuum insulation panel (VIP) is a new type of thermal insulation material with ultra-low
thermal conductivity. Most of the VIP core materials are petroleum based, which helps …

Polyurethane aerogels were prepared via sol–gel synthesis and dried with supercritical
carbon dioxide (CO 2) according to catalyst concentration. The influence of this parameter …

We describe a new room-temperature HCl-catalyzed method for the synthesis of
polybenzoxazine (PBO) aerogels from bisphenol A, formaldehyde, and aniline that cuts the …

We report the carbothermal synthesis of sturdy, highly porous (> 85%) SiC and Si3N4
monolithic aerogels from compressed polyurea-cross-linked silica xerogel powders. The …

Polyurea (PUA) develops H-bonding with water and is inherently hydrophilic. The water
contact angle on smooth dense PUA derived from an aliphatic triisocyanate and water was …
