3D printable soft and solvent-free thermoplastic elastomer containing dangling bottlebrush chains

Abstract

Polymer networks containing bottlebrush chains are emerging materials with exceptionally soft and highly tunable mechanical properties. However, such materials have not been extensively implemented in functional processing techniques such as...

One-step Synthesis of Fully Biobased Two-Sided Tapered ABA-type Thermoplastic Elastomers

“…The triblock structure also enables functional processing techniques such as 3D printing, making TPEs much broader applicable. 3 Commercially established examples are styrene (S)-, butadiene (B)-, and isoprene (I)-derived SBS and SIS block copolymers, used in a broad range of applications. Their properties can be tuned by various parameters, such as composition, molar mass, additives, and fillers.…”

“…They consist of a center block with a low glass temperature ( T g ) that offers flexibility and two vitrified high- T g outer blocks. , Consequently, processing by extrusion is much simpler as compared to covalently cross-linked elastomers, which must be cured in their final shape. The triblock structure also enables functional processing techniques such as 3D printing, making TPEs much broader applicable …”
