Embodiment 1
[0029] Example 1. Preparation of sheet-like light-to-heat conversion black material and its response to light
[0030] (1) Preparation of sheet-like light-to-heat conversion black material
[0031] Polyisoprene particles (0-100) with a certain Mooney viscosity are melted and hot-pressed into thin sheets at a certain temperature (60-300°C) and a certain pressure (0-100N), and cooled to room temperature (cooling speed is 10-200℃ / s);
[0032] Place the flakes in an airtight container (container size 1-10°C) saturated iodine vapor (temperature 0-200°C) 10 cm 3 ) at different times (placement time ranges from 1 second to 3 months) to complete the transition from non-conjugated polymers to light-to-heat conversion materials;
[0033] Treat the freshly prepared TPI flakes with ethanol (concentration can be 50% to 99.99%) until the ethanol is colorless, and dry in an oven (vacuum degree can be 0-10%) 5 pa, the oven temperature can be 0-200°C).

Embodiment 2
[0040] Example 2. Preparation and application of three-dimensional printing customizable light-to-heat conversion materials
[0041] (1) Preparation of printable trans 1,4-polyisoprene blending splines
[0042] Trans 1,4-polyisoprene strips were processed using a twin-screw extruder (Haake PolyLab, advance speed can be 1-1000 rpm). The mouth of the machine is equipped with a die to obtain a uniform spline with a diameter of about 0.1-100mm. In addition, polymers that can be blended in the trans 1,4-polyisoprene blending spline include polyethylene, polypropylene, polylactic acid, polyvinylidene fluoride, polyvinyl chloride, polystyrene, acrylonitrile - Butadiene - styrene, polyoxymethylene, polycarbonate, polyamide, acrylic plastic, polysulfone, polyphenylene ether and other thermoplastic polymers.

Abstract
The invention discloses a method for preparing a photothermal conversion material on the basis of iodine doping. The equipment provided by the invention is based on doping preparation of black materials so as to realize the scaled processing of photothermal conversion materials and to further realize the three-dimensional stereoscopic modeling processing precise customized physical therapy, wherein used materials comprise industrial rubber (trans-polyisoprene), elemental iodine and various high molecular materials capable of realizing blending. Compared with a conventional photothermal conversion material, the photothermal conversion material obtained by the method of the invention has the advantages that simplicity is realized; the acquisition is easy; the large-scale production and processing can be realized; the modeling forming and processing can be realized; the operation is convenient; through the fine structure printing, the firm foundation is laid for the subsequent wide application; wide application prospects can be realized in the high-end customized personnel nursing market. Through the characteristic of easy blending with various materials, the application in aspects ofphotothermal conversion, further pyroelectricity and the like can be realized with the help of other thermal response materials; a novel idea is provided for solving the environment problems of hazeremoval and the like.
Description
technical field [0001] The invention relates to the preparation and prospective application of a light-to-heat conversion material capable of mass customization, and belongs to the field of light-to-heat conversion materials. Background technique [0002] Near-infrared photothermal conversion, because it can improve the utilization efficiency of near-infrared light and enrich the utilization forms of near-infrared light, has played a pivotal role in the fields of cancer diagnosis and treatment, seawater desalination, etc., and has attracted extensive attention of many researchers. The development of light-to-heat conversion materials is a key challenge in this research field. [0003] Inorganic photothermal conversion materials have been widely studied, which can be divided into metal-based photothermal conversion materials, carbon-based photothermal conversion materials and semiconductor-based photothermal conversion materials. Metal-based photothermal conversion materials...
