Abstract

The invention discloses a photo-thermal patterned self-reinforced polymer material and a preparation method thereof, and belongs to the technical field of self-reinforced polymer materials. The photo-thermal patterned self-reinforced polymer material comprises the following raw materials: a monomer with a polymerized side chain containing an ester bond, an initiator, a photo-thermal conversion filler, an ester exchange reaction catalyst and a cross-linking agent. According to the present invention, the self-crosslinking polymerization reaction and the ester exchange reaction under the thermalor illumination condition are performed to obtain the polymer material capable of locally achieving the patterning self-enhancement, such that the same material has two different properties so as to meet the intelligent requirement on the material; and the preparation method of the polymer material is simple and easy to operate, the intelligent polymer material with different hardness degrees andspecific patterns can be obtained at the same time, practicability is high, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of self-reinforced polymer materials, in particular to a photothermal patterned self-reinforced polymer material and a preparation method thereof. Background technique [0002] Organisms in nature can change the strength of local tissues in the body structure in real time to meet various functional needs in survival, such as support, protection, and attack. At present, all artificial synthetic materials do not have such adaptive self-enhancement function. When a device requires both soft parts and hard parts, materials with different mechanical properties can only be combined and used by bonding and assembling. This leads to further bonding and assembly process issues, as well as material loss and waste. In addition, hard materials are often difficult to process and shape, and cannot be deformed and bent as needed when making devices. Although soft materials can easily make complex shapes, their shapes are...
