Abstract: Disclosed is a method for making an antimicrobial material from 1D nanometer silver that does not accumulate in a human body. At first, 1D nanometer silver is mixed in hydrophilic solution to produce 1D nanometer silver solution. Then, adhesive is blended in the 1D nanometer silver solution to produce the antimicrobial material. The antimicrobial material may be used in antimicrobial liquid, antimicrobial dressing or antimicrobial composite. Human skin can easily block the 1D nanometer silver. Therefore, the 1D nanometer silver does not enter or accumulate in the human body. Yet, the antimicrobial material exhibits a high bactericidal rate.

Abstract: A thermo-interface material composite uses a thermo-interface material containing silver nanowires. The silver nanowires have high aspect ratios, high thermo-conductivity coefficients and good anti-oxidation capabilities. Hence, an amount of silver nanowires can be added fewer than that of a traditional metal or ceramic powder. In this way, defects on device surface can be speckled during a dispersal process for improving adhesion between devices. Thus, a thermo-interface material is fabricated to obtain a high thermo-conductivity coefficient for further forming a thermo-channel.

Abstract: A composite bipolar plate for a polymer electrolyte membrane fuel cell (PEMFC) is prepared as follows: a) compounding vinyl ester and graphite powder to form bulk molding compound (BMC) material, the graphite powder content ranging from 60 wt % to 95 wt % based on the total weight of the graphite powder and vinyl ester, wherein 0.5-10 wt % modified organo clay by intercalating with a polyether amine, based on the weight of the vinyl ester resin, is added during the compounding; b) molding the BMC material from step a) to form a bipolar plates having a desired shaped at 80-200° C. and 500-4000 psi.

Abstract: A phenolic resin that increases its toughness by polydimethylsiloxane and a process of preparing the same is provided. Polydimethylsiloxane is added as a coupling agent in a ?-glycidoxypropyltrimethoxysilane-modified phenolic resin to improve the compatibility between polydimethylsiloxane and the phenolic resin. Then, tetraethoxysilane is added to conduct hydrolysis condensation and obtain tougher and thermally stable phenolic resin.

Abstract: The method of the present invention includes grafting a glycidyl alkylene trialkoxy silane to a novolac phenolic resin in an organic solvent to form a modified novolac phenolic resin; mixing a tetralkoxy silane, an acid and water with the resulting organic solution containing the modified novolac phenolic resin, wherein hydrolysis and condensation reactions are carried out to form a —Si—O—Si— bonding; adding a curing agent for novolac phenolic resin to the resulting reaction mixture; evaporating the organic solvent and acid from the resulting mixture and heating the resulting mixture to form a novolac phenolic resin/silica hybrid organic-inorganic nanocomposite.
