Disclosed is a type of modified polysiloxane having the following structural formula (I), wherein m is an integer between 0 and 10000; n is an integer between 0 and 10000; m and n cannot equal to 0 simultaneously; R 1 -R 7 are the same or different; at least one of R1-R7 comprises a group having a reversible chemical bond system based on a hydrogen bond, a coordinate bond, or a covalent bond. The present invention creatively uses polysiloxane as a main chain to introduce a reversible chemical bond having temperature sensitivity by a chemical method, so as to obtain a polymer material which is highly sensitive to temperature. By utilizing the temperature-sensitive properties of materials, functional materials with specific applications, such as medical external fixation materials, orthopedic materials, and packaging materials, can be obtained by particular processing and preparation methods. |
