Summary
This study enhances holographic gratings using modified polymethylmethacrylate (PMMA) with acrylic acid (AA) and phenanthrenequinone. The resulting gratings exhibit improved thermal stability up to 200°C and better adhesion to glass.
Area of Science:
- Materials Science
- Polymer Chemistry
- Optics
Background:
- Polymethylmethacrylate (PMMA) is a common polymer for holographic gratings.
- Improving thermal stability and substrate adhesion are key challenges for photopolymer applications.
- Existing materials often lack the required performance for demanding environments.
Purpose of the Study:
- To enhance the thermal properties of holographic gratings.
- To improve the adhesion of photopolymers to soda-lime glass.
- To investigate a modified PMMA system for holographic applications.
Main Methods:
- Radical copolymerization of methylmethacrylate (MMA) with acrylic acid (AA) to create modified PMMA.
- Incorporation of 9,10-phenanthrenequinone additives into the copolymer.
- Fabrication and thermal analysis (thermogravimetry, differential thermal analysis, thermal mechanic analysis) of holographic gratings.
Main Results:
- Modified PMMA films demonstrated improved adhesion to soda-lime glass.
- Holographic gratings recorded on the modified PMMA showed thermal stability up to 200°C.
- The thermal stability was found to depend on the copolymer composition and macromolecular structure.
Conclusions:
- Copolymerization of MMA with AA and addition of phenanthrenequinone effectively enhances PMMA's thermal properties.
- The modified PMMA is a promising photosensitive material for thermally stable holographic gratings.
- Further research can explore optimizing composition for even higher thermal performance and broader applications.
