Abstract: The present invention discloses a novel toughener selected from the group of polyurea, polyurethane and poly(urea-urethane) using a facile synthesis method. The toughener forms thick-interface particles, and creates an effective toughness improvement for epoxy resin. Different from the conventional epoxy/rubber composite or epoxy/thermoplastic composite, the epoxy/polyurea, epoxy/polyurethane, or epoxy/poly(urea-urethane) composite shows Newtonian rheological behaviour, a convenient property for processing. The unique feature of the toughener according to the present invention is that toughness can be significantly improved at low toughener content without losing other desirable properties.

Abstract: A method for modifying CNT is disclosed. The modified CNT by the above-mentioned method mixed with a resin is provided with an enhanced diffusibility; therefore the electronic property and mechanical property of resin are enhanced obviously with lower quantity of CNT.

Abstract: A modified thermally expandable graphite includes a reaction product of an expandable graphite that contains an intercalation compound intercalated among lattice layers of the expandable graphite, and a silicon-containing organic compound that has at least one alkoxyl group and a reactive group subjected to reaction with the intercalation compound. A sol-gel reaction product of the modified thermally expandable graphite and a modified thermosetting polymeric precursor is also disclosed.

Abstract: A method for preparing a carbon nanotube (CNT)/polyolefin composite by a water-crosslinking reaction and its preparation method are disclosed. Taking an embodiment for example, a carbon nanotube, an organic unsaturated silane and a plastic material are provided, and then the carbon nanotube and the organic unsaturated silane are mixed uniformly by a dispersant. The mixture is bonding with the plastic material by the silicon of organic unsaturated silane. A composite provided with a better combination of carbon nanotube and plastic material is generated by the method of the present invention.

Abstract: The recycled thermosetting flour composites and method for preparing the same are disclosed. The silane coupling agent is used as a coincidental bridge between recycled thermosetting flour and plastic materials, to apparently promote the mechanical properties of composites by linking with each other. As a result, the recycled polyolefin and recycled thermosetting flour are applied through interfacial modification, coupling, modification, mixing and granulating process to generate a composite with better mechanical properties and recycle the resource.

Abstract: A sterilizing air filter has a casing, a base, multiple spray devices, a cover, multiple fans and multiple bent tubes. The casing has an inlet and an outlet. The base is mounted in the casing and has multiple chambers in the base. Disinfectant can be poured into the chambers. The spray devices respectively mounted in the chambers and the cover fitted on the base are both used for spraying disinfectant in the chamber. The multiple fans and the multiple bent tubes are used for spreading the sprayed disinfectant between the different chambers and out to the air. The sterilizing air filter not only sucks the air into the microbial filter for sterilization and filtration but also automatically sprays the disinfectant out to the air to kill microbes in the air.
