Compared to conventional single-phase fluids, the latent functionally thermal fluid (LFTF), with phase change particles of μm magnitude in size dispersed in it, shows much greater apparent specific heat and heat transfer rate between the fluid and the duct wall. Therefore, for given heat transportation quantity, the mass flow rate and the pump consumption can be reduced greatly. Due to these, LFTF is a promising material in the fields of heat exchanging. In this paper, phase change material (n-tetradecane) was encapsulated by polymethyl mathacrylate (PMMA), polystyrene (PS) and blend of them by internal phase separation method to form microcapsule of 1~2μm in size. The chemical structures were demonstrated by using Fourier transform infrared spectroscopy (FTIR). The core-shell structure was observed using phase contrast microscope. Differential scanning calometry (DSC) results indicated that the phase change enthalpy of the containing 75wt% n-tetradecane as core material reaches 150.7 J/g.

Polymerization Induced Phase Separation

Porous polymers have been synthesized by an aza-Michael addition reaction of a multi-functional acrylamide, N,N′,N″,N‴-tetraacryloyltriethylenetetramine (AM4), and hexamethylene diamine (HDA) in H2O without catalyst. Reaction conditions, such as monomer concentration and reaction temperature, affected the morphology of the resulting porous structures. Connected spheres, co-continuous monolithic structures and/or isolated holes were observed on the surface of the porous polymers. These structures were formed by polymerization-induced phase separation via spinodal decomposition or highly internal phase separation. The obtained porous polymers were soft and flexible and not breakable by compression. The porous polymers adsorbed various solvents. An AM4-HDA porous polymer could be plated by Ni using an electroless plating process via catalyzation by palladium (II) acetylacetonate following reduction of Ni ions in a plating solution. The intermediate Pd-catalyzed porous polymer promoted the Suzuki-Miyaura cross coupling reaction of 4-bromoanisole and phenylboronic acid.
