Stress-memory polymeric filaments for advanced compression therapy

Abstract

Revelation of stress-memory behavior in smart polymeric filaments and its implications for compression stockings for advanced compression management.

Three birds, one stone – photo-/piezo-/chemochromism in one conjugated nanoporous ionic organic network

“…Considering that the external mechanical pressure is in a quasi-linear relationship to the detected ESR intensity (Fig. 5c), NION-Cl is expected to serve as a pressure sensor or a “pressure memory” material 18. For example, NION-Cl plastics can be processed by the mould casting technique (Fig.…”

Polyurethane: A Shape Memory Polymer (SMP)

“…They reported that this coated fabric showed satisfactory thermoelectric performance and good processability. In addition to that, medical stockings are also fabricated using SMPU for the treatment of chronic venous disorders [62][63][64]. This SMPUbased stocking allows controlling or managing the pressure exerted in a wrapped position and also produces extra pressure (up to 50%) by simply heating the stocking.…”

Research Progress in the Functional Textiles

“…Professor Narayana of Hong Kong Polytechnic University designed and manufactured a kind of medical compression socks based on shape memory polyurethane fiber, shown in Fig.3 [14] . It was found that the higher the stress and the higher the temperature, the stronger the stress memory property of the material.…”

“…3. Schematic of shape memory socks [14] Professor Bai of Donghua University had successfully grafted N-isopropylacrylamide (NIPAAm) onto reduced wool macromolecules based on thiol olefin click chemistry. Through the characterization, it was found that this kind of method that the group with shape memory effect was inserted into the original fabric structure by click chemical reaction could effectively endow the wool fabric with shape memory characteristics.…”
