Aerogels are lightweight solid materials that are prepared from organic or inorganic
materials or as composites and are explored as advanced materials for various applications …

The key issue of extrusion-based 3D printing of polyimide (PI) aerogels is the regulation of
the ink rheology. Herein, a novel freeze casting-assisted extrusion printing method is …

Nowadays, finding new materials with enhanced thermal insulation properties has become
a mandatory task to reduce energy consumption and CO 2 emissions. In recent years …

This article studies the effect of adding different contents of surface-modified multiwalled
carbon nanotubes (CNTs) on the structure and final properties of polyisocyanurate …

Highly transparent polyisocyanurate–polyurethane (PUR–PIR) aerogels were synthesized,
and their optical properties were studied in detail. After determining the density and …

A hydrogel-like product of the bacterial fermentation of coconut water is well-known as nata
de coco which contains low-cost and high-quality bacterial cellulose. In this work, nata de …

A novel synthesis of polyurethane foam/polyurethane aerogel (PUF–PUA) composites is
presented. Three different polyurethane reticulated foams which present the same density …

A family of transparent polyisocyanurate-polyurethane (PUR-PIR) aerogels with an
interesting combination of physical properties were synthesized. First, their textural …

Waterborne polyurethane (WBPUR) aerogels using acetone method and freeze-drying
procedure have been successfully synthesized. The morphology, chemical structure, and …

In this work, polyurethane aerogels are fabricated in re-entrant honeycomb forms to achieve
auxeticity and much higher flexibility than corresponding aerogel monoliths. For this …
