RM82

RM82 Reactive Mesogen — CAS 125248-71-7

RM82 molecular structure

Molecular Structure

A known precursor for liquid crystal elastomer (LCEs) inks that can be direct-write printed into 3D structures capable of reversible changes in shape, i.e., four-dimensional-printed (4DP) structures. LCE actuators (LCEAs) using RM82 showed both thermal, photo and chemical responsiveness, which may enable new generations of soft robotics, implantable medical devices and dynamic functional arquitecture, such as photoswitches. RM82 has also been used to create the mesogenic order in liquid crystalline vitrimers, allowing postpolymerization processing, while also minimizing unwanted creep during actuation.
This product can be used in Material Jetting or Vat polymerization 3D printing techniques.

Excellent Source to Support Your Research

Samples are available for evaluation before a first order. Tell us the quantity, the intended formulation and the documents you need — a specification sheet, a safety data sheet, a recent certificate of analysis — and we confirm against the current lot what can be supplied and on what lead time.

RM82 and RM257 are the C6 and C3 homologues of the same mesogenic core — a hexyloxy spacer here, a propoxy spacer on RM257 — and the spacer length is what separates them in transition temperature and in the stiffness of the cured network. They are not interchangeable: the choice follows the phase behaviour and the actuation the network has to deliver. See RM257 reactive mesogen, CAS 174063-87-7.
