Thermoresponsive Physically Cross-Linked Hydrogels with Bidirectional Optical Response for Smart Windows Application.

ABSTRACT: Hydrogel-based smart windows have the potential to reduce the energy consumption associated with air conditioning and lighting systems. Most existing hydrogels exhibit a unidirectional response to a specific temperature, limiting their applicability. In this work, a bidirectional temperature-responsive hydrogel was developed by incorporating hydroxypropyl cellulose (HPC) into a physically cross-linked copolymer matrix of N-(2-hydroxyethyl) acrylamide (HEAA) and acrylamide (AM), with cetyltrimethylammonium bromide (CTAB) used to stabilize lauryl methacrylate (LMA) micelles in a deep eutectic solvent (DES)/H₂O binary solvent system. At higher temperatures, the hydrogel becomes opaque through phase separation driven by the lower critical solution temperature (LCST) of HPC. A
