This property has drawn great attention in various fields, such as drug delivery, tissue engineering, and water treatment. However, PNIPAM alone does not possess sufficient mechanical strength, which limits its applications in biomedical and environmental fields. Copolymerization with other monomers is a promising strategy to enhance the mechanical properties of PNIPAM.In this project, we aim to synthesize a copolymer of acrylamide (AM), NIPAM, and N-phenylmaleimide (NPA), denoted as P(AM-NIPAM-NPA), and study its solution properties.Objectives:1. Synthesize the P(AM-NIPAM-NPA) copolymer using free radical polymerization.2. Characterize the copolymer structure using Fourier-transform infrared (FT-IR) spectroscopy.3. Investigate the temperature-sensitive behavior of P(AM-NIPAM-NPA) in aqueous solution.4. Evaluate the mechanical properties of the copolymer film.Methodology:1. P(AM-NIPAM-NPA) copolymer will be synthesized via free radical polymerization using AM, NIPAM, and NPA monomers.2. The copolymer structure will be characterized using FT-IR spectroscopy.3. The temperature-sensitive behavior of P(AM-NIPAM-NPA) in aqueous solution will be evaluated by measuring the transmittance of the solution at different temperatures using a UV-Vis spectrophotometer.4. The mechanical properties of the copolymer film will be determined by tensile testing.Expected outcomes:1. Successful synthesis of the P(AM-NIPAM-NPA) copolymer with desired properties.2. Confirmation of the copolymer structure using FT-IR spectroscopy.精品文档---下载后可任意编辑3. Temperature-dependent sol/gel transition behavior of P(AM-NIPAM-NPA) in solution.4. Improved mechanical properties of the copolymer film compared to PNIPAM alone.Significance:The P(AM-NIPAM-NPA) copolymer has the potential to be used in biomedical and environmental applications due to its temperature-sensitive behavior and improved mechanical properties. The findings of this study will contribute to the development of new materials with enhanced properties for practical use in various fields.
