Tannin-based rigid foams: a survey of chemical and physical properties.
TL;DR: It is shown that tannin-based rigid foams, prepared from 95% natural material, can compete with synthetic ones for most of traditional applications and are fully comparable with those of their phenolic counterparts.
Journal ArticleDOI
Effect of composition and processing parameters on the characteristics of tannin-based rigid foams. Part I: Cell structure
TL;DR: In this paper, the pore structure of Tannin-based rigid foams and derived glass-like carbon foams is investigated. But the results show that pore structures are mainly controlled by the amount of blowing agent, leading to a linear cell density that typically ranges from 50 to 250 pores per inch.
Journal ArticleDOI
Mechanical properties of tannin-based rigid foams undergoing compression
TL;DR: In this article, the mechanical properties of a new class of extremely lightweight tannin-based materials, namely organic foams and their carbonaceous counterparts are detailed, and scaling laws are shown to describe correctly the observed behaviour.
Journal ArticleDOI
Effect of composition and processing parameters on the characteristics of tannin-based rigid foams. Part II: Physical properties
TL;DR: In this paper, the effects of changing a few experimental parameters that have been varied in the synthesis of the foam: amounts of blowing agent, strengthener and nanofillers, shape of the moulds and restricted foaming are discussed in relation with the pore structure observed in the companion paper.

TL;DR: In this paper, the effects of two experimental parameters: KOH/anthracite weight ratio (W) and activation temperature (T) on the hydrogen storage capacity were studied by application of central composite design and response surface methodology.
