Molecular Weight of Step-Growth Polymers

Molecular Weight of Step-Growth Polymers

Step growth polymerization involves bi or multifunctional monomers. Bifunctional monomers react to form linear step growth polymers, whereas multifunctional monomers react to form non-linear or branched polymers.
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
The extent of the...

Background:

For two decades, research has focused on combining shape-memory polymers (SMP) with carbon nanotubes (CNT).
The goal was to enhance mechanical properties and shape fixity of SMPs through CNT reinforcement.
CNT's unique properties also enable novel actuation mechanisms like electro- and photo-thermal responses.

To explore the potential of these composites for soft actuator development.

Main Methods:

Review of existing literature on the synthesis and characterization of SMP/CNT composites.
Analysis of studies focusing on thermoset and thermoplastic matrices.
Investigation of CNT's influence on the response of nanocomposites to external stimuli.

Main Results:

SMP/CNT composites exhibit enhanced mechanical properties and shape fixity.
CNT incorporation enables electro- and photo-thermal actuation in SMPs.
These composites demonstrate advantages such as fast actuation, remote control, and complex shape deformation.

Conclusions:

SMP/CNT composites are promising for developing advanced soft actuators.
Their multifunctionality and performance characteristics are suitable for tissue engineering and soft robotics.
Further research continues to unlock the potential of CNT in polymer nanocomposites for external stimuli response.
