Lignin-Based Triple Shape Memory Polymers
No full textLignin-based triple shape memory
polymers comprised of both permanent
covalent cross-links and physical cross-links have been synthesized.
A mixing phase with poly(ester-amine) and poly(ester-amide) network
having two distinct glass transitions was hot mixed with more structurally
homogenized methanol soluble lignin fraction by one-pot, two-step
method. Triple shape properties arise from the combined effect of
the glass transition of polyester copolymers and lignin and the dissociation
of self-complementary hydrogen bonding and cross-link density. The
percentage of recovery in each stage was investigated and it was proved
that the first recovery is related with lignin-poly(ester-amine) rich
network and the second recovery stage is related with lignin-poly(ester-amide)
rich network. The thermal and mechanical properties of the lignin-copolymer
networks were also investigated using differential scanning calorimetry
and dynamic mechanical analysis
