Study on Photothermal Effect and Light-responsive Shape Memory Behavior of PDA/EA Photopolymer Resin
By introducing polydopamine (PDA) to enhance cross-linking and interfacial interactions, a series of polydopamine/epoxy acrylate (PDA/EA) cured products with various ratios were prepared and analyzed using methods such as dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA). The results show that the incorporation of PDA effectively increased the storage modulus, cross-linking density, peak temperature of loss modulus, and thermal stability of the materials. Additionally, PDA/EA materials exhibited good photothermal effects under NIR light, with desirable light absorption, photostability, and light controllability. Especially under 808 nm NIR light with an intensity of 1 W/cm², the cured material of PDA-EA-0.1 could complete photo-responsive shape recovery within 60 s. PDA/EA cured products have excellent photothermal conversion efficiency and shape memory properties, and they hold broad prospects for application in fields such as photothermal therapy and micro/nanostructure control.
