Phase change material microcapsules are obtained using a PMMA prepolymer and an organic-solvent free synthesis process. A polymer monomer and an initiator are subject to pre-polymerization in a water bath to form Polymethyl methacrylate (PMMA) prepolymer which is then prepared to be a stabilizer aqueous solution. A phase change material is added to the stabilizer aqueous solution and liquefied in advance, and stirred to form an emulsion by a homogenizing mixer. A starting agent, a cross-linking agent and a Polymethyl methacrylate methyl ester prepolymer are added to the emulsion containing the phase-change material. The emulsion is further stirred by the homogenizing mixer for micro-emulsification which then aggregates in water bath. In this way, the process may use organic-solvent free process to pre-polymerize the polymer monomer into a Polymethyl methacrylate prepolymer and carries out encapsulation and polymerization at an oil-water interface to achieve the preparation of phase change material microcapsules.

A method for manufacturing a conductive adhesive containing a one-dimensional (1D) conductive nanomaterial is revealed. The method produces a conductive adhesive by mixing the 1D conductive nanomaterial with water-based or solvent-based resin solution. The conductive adhesive has good industrial applications, not influenced by industrial adaptability and environmental adaptability. The conductive adhesive obtained also has better conductivity. Moreover, the amount of the 1D conductive nanomaterial used in the present invention is less than the amount of conductive nanoparticles used and the cost is reduced effectively.
