研究目的
To develop a novel fluorescent hydrogel actuator with pH and thermo dual responsiveness.
研究成果
The study successfully developed a novel fluorescent hydrogel actuator with pH and thermo dual responsiveness, demonstrating potential for applications in smart materials. The hydrogel's ability to change fluorescence and shape under external stimuli offers new insights into the design of stimuli-responsive materials.
研究不足
The study focuses on the dual responsiveness of the hydrogel to pH and temperature, but the practical applications and long-term stability under varying environmental conditions are not extensively explored.
1：Experimental Design and Method Selection:
The study involves the incorporation of pH-responsive perylene tetracarboxylic acid (PTCA) into an anisotropic poly(N-isopropylacrylamide)–polyacrylamide (PNIPAm-PAAm) structure to create a hydrogel with dual responsiveness.
2：Sample Selection and Data Sources:
PTCA was grafted onto gelatin, and the hydrogel was prepared through stepwise polymerization.
3：List of Experimental Equipment and Materials:
PTCA, gelatin, N-isopropylacrylamide (NIPAm), acrylamide (AAm), UV light for polymerization.
4：Experimental Procedures and Operational Workflow:
The hydrogel's fluorescence and shape deformation properties were tested under varying pH and temperature conditions.
5：Data Analysis Methods:
Fluorescence intensity and shape deformation were measured to assess the hydrogel's responsiveness.
