Abstract: The present invention provides new impact protection materials and the method of making the same. More specifically, the impact protection materials are polymer-based shear-thickening composite comprising a non-shear-thickening polymer matrix material and one or more shear-thickening materials. Preferably, the non-shear-thickening polymer matrix material is in an amount from approximately 5 weight percent to approximately 90 weight percent with the balance being one or more shear-thickening materials. The first type of the one or more shear-thickening materials is sol-gel based shear-thickening material in which small inorganic particles are connected in a gel network; the second type is polymer-based shear-thickening material in which polymer chains form network. Compared to the existing shear-thickening materials, the present shear-thickening materials have different molecular structure and formulation and possess properties of good impact protection and good stability.

Abstract: The present invention relates to new fullerene derivatives of formulae 1a-d, 2 and 3: method of synthesizing said derivatives, and applications thereof in organic photovoltaics, e.g., organic solar cells. In particular, the fullerene derivatives of the present invention are soluble in non-halogenated solvents such that an environmental-friendly and low-cost fabrication method for industrialization of solar cell based on the new fullerene derivatives is provided. An ink formulation for forming a thin film on a substrate of organic photovoltaics comprising at least one of the fullerene derivatives of the present invention is also provided. Greater than 3% power conversion efficiency of the organic solar cells (area=0.16 cm2) formed based on the fullerene derivatives of the present invention with less pollution and lower cost in fabrication can be achieved in the present invention.
