Abstract: The disclosure relates to a method for the surface treatment of a polyester fiber, a modified polyester fiber obtained therefrom, and an engineered cementitious composite containing such modified polyester fibers. The method comprises subjecting the polyester fiber to an alkali hydrolysis to obtain hydrolyzed polyester fiber; applying a solution containing an acid cross-linker and a polyvinyl alcohol to the hydrolyzed polyester fiber, then curing to form a coating having a thickness of sub-micron or micron scale on the polyester fiber, thereby obtaining the modified polyester fiber.

Abstract: A soft magnetic composite (SMC) material is formed from atomized ferromagnetic particles. The particles of a predetermined size range are formed and are coated with at least one layer of electrically insulating nano-sized inorganic fillers to form insulated ferromagnetic powder as the SMC material. The particles are further coated with a lubricating agent to facilitated demoulding.

Abstract: The invention provides a process for preparing an overvoltage protection material comprising: (i) preparing a mixture comprising a polymer binder precursor and a conductive material; and (ii) heating the mixture to cause reaction of the polymer binder precursor and generate a polymer matrix having conductive material dispersed therein, wherein the polymer binder precursor is chosen such that substantially no solvent is generated during the reaction.
