Abstract

The invention relates to the technical field of optical part processing, and provides a solvent composition for disassembling a flexible optical device; thesolvent composition comprises the following components, by weight, based on 100% of the total mass of the solvent composition: 35-45% of C1-C7 chain alkane, 20-30% of a ketone solvent, and 35%-45% of an ester solvent; the solvent composition is used for effectively dissolving the optical cement, so that the optical cement is weakened to disappear, the device is separated, the optical device is not corroded, the surface roughness is not changed, the solvent composition can be used for effectively removing an optical cement layer of the ultrathin flexible optical device, the corrosion is avoided, scratches cannot be generated on the attaching surface of the optical device, the obtained flexible optical device cannot deform or warp after being disassembled, and the optical device with the ultrathin OCA optical adhesive layer can be disassembled and repeatedly used.

Description

technical field [0001] The application belongs to the technical field of optical parts processing, and in particular relates to a solvent composition for disassembling flexible optical devices and its application. Background technique [0002] Flexible photonic devices are not limited by the rigid physical state of traditional optoelectronic devices. The bendable, foldable, and stretchable forms enable the unique optoelectronic properties of the device to be realized and regulated, which greatly expands the development model and application space of traditional optoelectronic devices. Combining New functional optical materials, device integration technology, and the advantages of photonic devices over electronic devices in material-specific sensing, channel capacity, and anti-electromagnetic interference capabilities. Flexible optical devices can be applied to wearable sensing, high-speed optical interconnects, and optical fields. Regulation, bio-optogenetics, etc., are wide...
