Two-photon initiated polymerization

Two-photon-initiated polymerization (TPIP) can easily produce three-dimensional holographic pattern. The scheme of TPIP is shown in Figure 5.22. Areas encountering double beams of 745 nm (near-infrared laser) are polymerized by two photons. Scanning double beams produce a three-dimensional structure. Kondo et al. reported on a two-photon-initiated polymerization system. A composite of the TPIP is shown in Figure 5.23. [Pg.156]

Fig. 39 Micrograph of polymerized uniform submicrostructure with 9 p.m line width and 50 xm line spacing. The structure was written by two-photon initiated electron-transfer free radical polymerization of diacrylate monomer Sartomer SR 349 at 775 nm via direct excitation of dye 5,7-diiodo-3-butoxy-6-fluorone(H-Nu 470) for (A) and dye 3 for (B) in the presence of Ar,Ar-dimethyl-2,6-diisopropylaniline...

Polymerization of styrene and p-isopropylstyrene could be photo-initiated with radiation from the ruby laser in the absence of photosensitizers and oxygen Since ordinarily no unsensitized photoinitiation of styrene is detected for wavelengths longer than 4000 A, the results of this experiments must be due to two-photon processes. [Pg.40]
