The surface of photo-sensitive porous honeycomb-patterned film was prepared by polycaprolactone(PCL) composites containing photochromic azobenzene (Azo) molecule. The surface morphology and hydrophobic interaction of the porous honeycomb-patterned PCL polymer composites film were significantly changed by the UV illumination. We compared photo-sensitive properties between porous honeycomb-patterned film and non-porous flat film. The PCL polymer composites changing properties by UV and visible light illumination were fabricated through ring opening polymerization of ɛ-caprolactone in the presence of different Azo amounts in part 1. Porous honeycomb-patterned polymer films were fabricated by casting the polymer solution under humid conditions; and non-porous flat films were also prepared by drying the polymer solution at ambient condition. Water contact angle was compared between porous patterned and non-porous flat films and was reversely changed by UV and visible light illuminations. The contact angle of PCL-Azo composite film was decreased by UV illumination and was recovered with visible light illumination. Reversals in contact angles by UV and visible light can be interpreted by photo-switched isomerization of the Azo component in the polymer composite films due to isomeric structural changes between trans- and cis- isomers inducing the dipole moment of the films by switching from trans- to cis-isomer. Futhermore, the porous honeycomb-patterned film had more sensitive properties than non-porous flat film by UV and visible light irradiation. In Part 2, PCL-reduced graphend oxide (rGO)-Azo polymer composties were fabricated through ring opening polymerization of ɛ-caprolactone in the presence of rGO-Azo composites. The rGO-Azo was synthesized through chemical bonding between rGO and Azo. The porous honeycomb-patterned films were fabricated using PCL-rGO-Azo composites by casting the polymer composite solution under humid conditions. The effect of UV and visible light irradiation for the conductivities and wettability was studied on the porous honeycomb-patterned and non-porous flat polymer composite films. Conductivity was reversibly changed by the UV and visible light irradiation, in which it was increased by UV irradiation while recovered by visible light irradiation. The increase of conductivity by UV illumination can be interpreted by the effect of isomerization of azobenzene component in the composite from trans- to cis- isomer inducing change of length of azobenzene molecules. The conductivities of the porous honeycomb- patterned film was more photo-sensitive than non-porous flat film by UV and visible light irradiation. Water contact angle was also compared between porous patterned and non-porous flat films, and was reversely changed by UV and visible light illuminations. The reversible swithcing can be interpreted by photo-switched isomerization of the Azo component in the polymer composite films due to isomeric structural changes between trans- and cis- isomers inducing the dipole moment of the films by switching from trans- to cis-isomer. The porous honeycomb-patterned film had also more sensitive properties than non-porous flat film by UV and visible light irradiation.
