3D-PRINTABLE SEBS BASED TERNARY

Heat-activated shape memory polymers (SMPs) have received great
attention in both industry as well as academia throughout the last years.
Traditional dual SMPs canmemorize only one temporary shape, whilemultiple
SMPs can memorize more than one temporary shapes. Unlike the above two
categories of SMPs, tunable SMPs are not limited by the number of temporary
shapes and have capability to adjust deformation temperatures optionally.
Additive manufacturing, also known as three-dimensional (3D) printing, is
a remarkable burgeoning technique which drives major innovations in the
fields of manufacturing, architecture, healthcare and education. To date,
3D printing with SMPs have attracted lots of interest. In comparison with
current 3D-printable dual SMPs or multiple SMPs, 3D-printable tunable SMPs
have possibility to implement more complex and sequential shape change
process vividly in a pre-programmed way, which is of great significance for
applications such as flexible electronics, electrical actuators, intelligent
biomedical scaffolds, etc. In thiswork, we reporteda facilestrategy to fabricate
tunable shape memory polymer blends with the feasibility of 3D printing
simultaneously. A series of tunable SMPs consist of styrene-b-(ethylene-co-
butylene)-b-styrene (SEBS) ternary blends, exhibiting good dual, triple and
quadruple shape memory effect, moreover, such shape memory behaviors
can be tuned in a broad temperature range via the selection of deformation
temperatures alone, demonstrating that this blend have good tunable shape
memory effect. This tunable SMPs are easy to be processed and suitable
for a fused deposition modeling 3D printer. Considering the inexpensive and
environmental sources as well as easy processing, our reported strategy has
great potential in many application fields.
