Problems solved by technology

Traditional magnetic storage such as mobile hard disks, SSD solid-state storage, and existing optical storage media such as DVDs and Blu-ray discs generally have a limited data storage life, usually in the range of three to fifty years, and it is difficult to meet the long-term requirements spanning centuries and centuries. data storage requirements
[0003] At present, there are many studies on optical storage materials, including inorganic transparent media or organic types. However, some organic storage materials have insufficient chemical, temperature, optical, electrical and mechanical stability, and poor fatigue resistance, which leads to data loss. It cannot be stored for a long time after writing. In addition, the storage threshold of some storage materials is relatively high, which leads to low data writing efficiency and high cost. Super large storage capacity to break through the shortcomings and deficiencies of traditional optical storage media such as low lifespan and low storage density

Embodiment 1

[0052] This embodiment provides, on the one hand, a composite material supporting four-dimensional optical data storage, comprising the following components by weight percentage: 99% of an acrylic monomer, and 1% of a thermosensitive compound, wherein the thermosensitive compound is two Zinc ethyl dithiocarbamate.

[0053] The acrylic monomer is dipentaerythritol pentaacrylate, the brand name is SR-399NS.

[0054] Another aspect of the present embodiment provides a method for preparing a composite material supporting four-dimensional optical data storage, comprising the following steps:

[0055] S1. Mix SR-399NS acrylic monomer and zinc diethyldithiocarbamate, add chloroform, stir ultrasonically for 15 minutes to make it evenly dissolved to obtain a liquid mixture, then place it in a vacuum heating box and evaporate the chloroform to dryness at 60°C The solvent is then placed for 48 hours, and the chloroform solvent is completely volatilized and pumped away by a vacuum pump t...

Embodiment 2

[0058] One aspect of this embodiment provides a composite material supporting four-dimensional optical data storage, which includes the following components in weight percentage: 69.3% of acrylic monomer, 29.7% of reactive diluent, 1% of thermosensitive reactive compound, the thermosensitive The reaction compound is zinc diethyldithiocarbamate.

[0059] The acrylic monomer is dipentaerythritol pentaacrylate, the brand name is SR-399NS.

[0060] The reactive diluent is pentaerythritol triacrylate, the brand name is SR-444NS.
