Abstract: A recyclable vitrimer polymer composition includes: a first monomer containing at least one amine group at the terminal thereof; and a second monomer containing at least one acrylate group at the terminal thereof. The N—H group of the first monomer and the acrylate group of the second monomer react with each other in a ratio of 1:0.5 to 1.5.

Abstract: A polymer having a UV-responsive self-healing function at room temperature and its manufacturing method are disclosed herein. More specifically, the solid dynamic crosslinked polymer with a UV-responsive self-healing function is capable of being repaired and reprocessed through a dynamic exchange reaction of disulfide induced under exposure to UV radiation at ambient temperature when damaged after curing. The novel polymer with a UV-responsive self-healing function is capable of self-healing simply through UV exposure at ambient temperature. Therefore, it can be utilized in the recycling of thermosetting resins that are environmentally challenging to recycle in the plastic industry, and furthermore, serve as an alternative to address various environmental issues.

Abstract: A mobile terminal including an output unit configured to output information; a receiving device configured to receive information from an external device; a controller configured to receive body condition information about a physical condition of a user while specific information is being received by the receiving device or output by the output unit, analyze the body condition information and estimate an emotional state of the user based on the body condition information, generate tag information indicating the estimated emotional state of the user, store the generated tag information with data corresponding the specific information, and output the generated tag information and the data corresponding to the specific information.

Abstract: A mobile terminal including a wireless communication unit configured to perform wireless communication; a display unit configured to display information; and a controller that executes an agent to extract and record information about a usage pattern of a user, and displays an icon corresponding to the executed agent differently based on a number of times information related to the executed agent is extracted.
