Аннотация
Plates of poly-MDP-2 porous material with a characteristic size of inhomogeneities of 0.3, 0.7, 2.5, 10, and 20 µm were synthesized by the photopolymerization technique. The conditions for the photolytic modification of the hydrophilic/hydrophobic properties of poly-MDP-2 by the graft copolymerization method under visible light irradiation were selected using 9,10-phenanthrenequinone as a photoinitiator and isodecyl methacrylate as a modifying monomer. It is shown on the samples with an inhomogeneity size of 10 µm that the stable hydrophobization effect (contact angle of water droplet θ = 135°) is achieved at a photoinitiator concentration of 2.4 · 10−3 mol L−1 and an irradiation time of the sample in the modifying solution of 1 h. The effect of photolytic hydrophobization increases with an increase in the size of inhomogeneities in the porous polymer material and reaches θ = 140° for inhomogeneities ∼20 µm in size.
