The reason is that the graphene oxide is layer structure,and it’s almost adiabatic in the vertical direction of the lamella.
After scattering graphene oxide into phenolic foam, due to the structure characteristics of graphene oxide, the transfer of heat in the phenolic foam is blocked, thus the thermal conductivity of foam gets reduced.
The influence of graphene oxide on the micro structure of the phenolic foam Fig. 4 The infrared spectrum of graphene oxide modified phenolic foam Fig. 4 is the infrared spectrum of phenolic foam when adding 0.5 g graphene oxide.
According to the graph, the strong absorption peak appears in 1649cm-1, which mainly comes from carbonyl group of the structure of PVP.

Abstract.
The TEM micrographs as well as N2 adsorption–desorption measurements show that the prepared products exhibited wormlike pore structures.
The lacking of distinct crystalline structure can be confirmed by the selected area electron diffraction (SAED) pattern of the sample.
It indicates that the nanoporous structures are achieved.
The prepared sample possessed anatase phases and showed wormhole-like mesoporous structures.

In geopolymer chemistry, every Al atom required one Na atom to reach equilibrium [8].
It can be seen that the amorphous lamellar structure of straw-geopolymer is consistent with pure geopolymer.
No porous structures were observed.
The lamellar structure of straw-geopolymer was still clearly visible.

Like the framework [{Fe(NCS)2}3(TPB)4] we reported[34], three types of cages, M6L4, M12L8 and M12L24, existed in the structure, which allowed for access and exchange of guest species.
The construction of such nanoporous SCOFs provides an opportunity to investigate the influences of guest molecules on SCO behavior and host-guest chemistry.
