Preparation And Characterization Of Poled Polymer Functional Thin Films

Poled polymer material with higher second order and third order nonlinear coefficient, low capacitance, excellent underlay compatibility, excellent processability characteristics,played an important role in the filed of the intergation optcs.In this thesis, the main work is starting from a new organic polymer asymmetric membrane structure, design and synthesis of new chromophore molecules DRCB, preparation of new polymers, with electric field induction methods, can be prepared with a stable second-order nonlinear poled polymer optical film. In the role of polarization plate electric field and exposure to UV light, the second order nonlinear optical film prepared material comprising covalently bonded network structure of the double coach silicone structure.For the classical DR1-PMMA system, the first induction treatment with solvent vapor method DR1-PMMA composite film for effective treatment, the treated film to detect a strong nonlinear optical signal, the method avoids the polymerization in a conventional polarization was prepared during the process of heating and electric fields to improve production efficiency, simplify the preparation process, no pollution, easy to operate, controllable conditions, provide an effective means for preparating thin films with organic nonlinear optical materials.
