Biobased, foam-like polyester composite materials were 3D-printed from a thermoset paste formulation. This formulation was composed of sebacic acid, glycerol, citric and cellulose nanocrystals in water ethanol with potassium chloride as salt porogen. Thin walls lattices geometry selected to facilitate post-printing processes such removal during curing the post-curing The compressive performance...

Suberin is a lipophilic macromolecule found in specialized plant cell walls, wherever insulation or protection toward the surroundings is needed. Suberized cells form the periderm, the tissue that envelops secondary stems as part of the bark, and develop as the sealing tissue after wounding or leaf abscission. Suberin is a complex polyester built from poly-functional long-chain fatty acids (sub...

Polyhydroxyalkanoate (PHA), produced by mixed microbial cultures (MMCs), is a biodegradable biopolyester that alleviates the global plastic crisis in nearest future. Even PHA has become research hotspot, reviews on composition determining thermodynamic and processing properties of products are rare. The primary focus evaluation relies factors affecting monomer MMC-PHA production. Besides, since...

Atomic force microscopy, FT-IR spectroscopy, and solid-state nuclear magnetic resonance have been used to improve our current knowledge on the molecular characteristics of the biopolyester cutin, the main component of the plant cuticle. After comparison of samples of cutin isolated from young and mature tomato fruit cuticles has been possible to establish different degrees of cross-linking in t...
