“…Lignin and tannin, two phenolic biopolymers, have also been used as aerogel precursors . Lignin aerogels have been prepared from wheat straw by cross‐linking lignin with oligo(alkylene glycol)‐α,ω‐diglycidyl ethers . Tannin polymers often substitute resorcinol and copolymerize with formaldehyde to form resins that can be pyrolyzed to carbon aerogels or xerogels (Figure ).…”

Biopolymer aerogels were among the first aerogels produced, but only in the last decade has research on biopolymer and biopolymer-composite aerogels become popular, motivated by sustainability arguments, their unique and tunable properties, and ease of functionalization. Biopolymer aerogels and open-cell foams have great potential for classical aerogel applications such as thermal insulation, as well as emerging applications in filtration, oil-water separation, CO capture, catalysis, and medicine. The biopolymer aerogel field today is driven forward by empirical materials discovery at the laboratory scale, but requires a firmer theoretical basis and pilot studies to close the gap to market. This Review includes a database with over 3800 biopolymer aerogel properties, evaluates the state of the biopolymer aerogel field, and critically discusses the scientific, technological, and commercial barriers to the commercialization of these exciting materials.

Biopolymer‐Aerogele gehören zu den ersten Aerogelen, die hergestellt wurden, aber erst im letzten Jahrzehnt kam es zu einer Belebung der Forschung über Biopolymer‐ und Biopolymer‐Verbundstoff‐Aerogele, die durch Fragen der Nachhaltigkeit, einstellbare spezielle Eigenschaften und einfache Funktionalisierung motiviert wird. Biopolymer‐Aerogele und offenzellige Biopolymer‐Schäume haben Potenzial für klassische Aerogel‐Anwendungen wie Wärmedämmung und neue Anwendungen bei der Filtration, Öl‐Wasser‐Trennung, CO2‐Abscheidung, Katalyse und in der Medizin. Das Gebiet der Biopolymer‐Aerogele wird heute von der empirischen Materialentwicklung auf dem Labormaßstab beherrscht und benötigt eine bessere theoretische Grundlage und Test in Pilotanlagen. Unser Aufsatz umfasst eine Datenbank mit über 3800 Biopolymer‐Aerogel‐Eigenschaften, beurteilt den Forschungsstand auf dem Gebiet und diskutiert wissenschaftliche, technologische und wirtschaftliche Hindernisse bei der Kommerzialisierung dieser faszinierenden Materialien.

“…Recent interest in lignin is focused on the production of aromatic chemicals (Lee et al 2016), platform intermediates (Wang et al 2013), polymer filler (Mousavioun et al 2010), and water-reducing admixture. In addition, lignin is also expected to be used in micro-and nano-structured lignin-based materials (Duval and Lawoko 2014), such as aerogels (Perez-Cantu et al 2014), nanoparticles (Frangville et al 2012;Yang et al 2016), and microcapsules (Norgren and Edlund 2014). Alkaline lignin is the preferred substrate for functionalized lignin-based materials due to its good solubility and formability in organic mediums.…”

The lignin degradation and its structural change as a result of catalytic steam explosion pretreatment can be considered of great importance for both the subsequent fermentation and the further utilization of the lignin fraction. This work investigated the degradation mechanism and change in the characteristics of lignin during dilute sulphuric-acid catalytic steam explosion (SE) pretreatment and ammonia catalytic steam explosion (AE) pretreatment of corn stalk. For this purpose, two types of lignin samples obtained from the two pretreatments of aqueous products and solid residues were fractionated, and they were then characterized by a series of comprehensive analyses that consisted of gas chromatography-mass spectroscopy (GC-MS), ion chromatography (IC), Fourier transform infrared (FT-IR), Carbon-13 nuclear magnetic resonance ( 13 C NMR), Carbon-Hydrogen two-dimensional heteronuclear single quantum coherence ( 13 C-1 H 2D HSQC), pyrolysis-GC-MS (Py-GC-MS), and field emission scanning electron microscopy (FE-SEM). Overall, the characteristic diversity of the lignin provides useful reference for highvalue applications of lignin.
