WebSep 13, 2013 · The braid bias angle and muscle chirality can be selected so that pores either open or close during heating. Using novel textile weaves, comfort-adjusting clothing might be created by combining polymer muscles having large thermal contractions (up to 1.2%/°C, Fig. 4C) with those that thermally expand, to thereby amplify textile porosity changes.

WebArtificial Muscle. 55 An interest in artificial muscle materials brought together the ROMP of a norbornenyl liquid crystal monomer and the ATRP of n-butyl acrylate off the initiator endcapped polynorbornene derivative to yield a liquid crystal/isotactic diblock adopting a lamellar structure. From: Polymer Science: A Comprehensive Reference, 2012 WebArtificial muscle has been a topic of intensive research for years [133–136]. The most exciting recent development is probably the discovery of polymer artificial muscle, which could contract fast and deliver large strokes (suggesting high ductility) from inexpensive high-strength polymer fibers, such as commercial fishing lines [136].
