Free-Standing and Self-Crosslinkable Hybrid Films by Core–Shell Particle Design and Processing
The utilization and preparation of functional hybrid films for optical sensing applications and membranes is of utmost importance. In this work, we report the convenient and scalable preparation of self-crosslinking particle-based films derived by directed self-assembly of alkoxysilane-based cross-linkers as part of a core-shell particle architecture. The synthesis of well-designed monodisperse...
متن کاملAn Evaporative Co-assembly Method for Highly-Ordered Inverse Opal Films
Colloidal self-assembly holds promise for photonic applications as a solution-based, low-cost alternative to top-down photolithography, if significant control of uniformity and defects can be achieved. Herein we demonstrate a new evaporative co-assembly method for highly-uniform inverse opal thin films that involves the self-assembly of polymer colloids in a solution containing a silicate precu...
متن کاملPhotonic Crystal-Based Sensors for Detecting Alcohol Concentration
Polystyrene (PS) opal and titania (TiO2) inverse opal films were fabricated by the self-assembly colloidal crystal template technique. Based on Bragg’s law, these sensors were used to detect the different concentrations of ethanol solution. The results indicated that TiO2 inverse opal films were advantageous over PS opal film for detecting the ethanol concentration. TiO2 inverse opal films sint...
متن کاملPhotonic bandgap of inverse opals prepared from core-shell spheres
In this study, we synthesized monodispersed polystyrene (PS)-silica core-shell spheres with various shell thicknesses for the fabrication of photonic crystals. The shell thickness of the spheres was controlled by various additions of tetraethyl orthosilicate during the shell growth process. The shrinkage ratio of the inverse opal photonic crystals prepared from the core-shell spheres was signif...
متن کاملPhoto-responsive photonic crystals for broad wavelength shifts.
A facile method to realize photo-responsive inverse opal photonic crystal polymer (IOPP) films with an adjustable broad-wavelength-range photonic band gap (PBG) was demonstrated in this communication. When immersing the IOPP film in malachite green carbinol base (MGCB) solution, under light irradiation, the MGCB released hydroxide ions. In this way, optical signals were converted to chemical si...
