Abstract

w przypadku optyki zintegrowanej. Najwiêcej miejsca pooewiêcono obszernemu omówieniu materia³ów NLO opartych na ¿ywicach epoksydowych (EP) wyró¿niaj¹cych siê ³atwooeci¹ przetwórstwa oraz orientacji aktywnych optycznie cz¹steczek a tak¿e ma³ymi stratami optycznymi w porównaniu z innymi materia³ami polimerowymi. Scharakteryzowano metody otrzymywania i w³aoeciwooeci u¿ytkowe opartych na EP materia³ach NLO usieciowanych ró¿nymi metodami (aminami, pod wp³ywem oewiat³a, w uk³adzie zol/¿el), w tym epoksydowych materia³ów NLO typu IPN. S³owa kluczowe: ¿ywice epoksydowe, nieliniowe w³aoeciwooeci optyczne, synteza, stabilnooeae termiczna. APPLICATIONS OF EPOXY RESINS IN ELECTRONICS AND OPTOELECTRONICS. PART III. EPO-XY RESINS WITH NONLINEAR OPTICAL PROPERTIESSummary -In the review the basic problems concerning nonlinear optical properties (NLO) of the materials (classical inorganic materials, organic crystals and polymeric materials showing many advantages) were discussed. Applications of polymers make possible the preparation of thin layers (a few to a few dozen of µm) of NLO materials which are necessary in case of integrated optics. The most attention has been paid to wide discussion of epoxy resin (EP) based NLO materials distinguishing themselves with ease of processing and orientation of optically active molecules as well as low optical losses in comparison with another polymeric materials. The methods of preparation and functional properties of EP based NLO materials, various ways cured (with amines, by light, in sol-gel system), including IPN type EP based NLO materials (Scheme B-H, Table 1) were characterized.
