    摘要： An organic semiconductor crystalline film and weak oriented epitaxy growth preparation method thereof. The organic semiconductor crystalline film is a n-type semiconductor or a p-type semiconductor, and organic semiconductor crystal molecules in the organic semiconductor crystalline film are oriented in a stand-up manner on the ordered substrate, and have an oriented relationship with the ordered substrate. The organic semiconductor crystalline film prepared by the present invention is useful for organic transistor and organic phototransistor devices. The method of the present invention can control the high carrier mobility direction of organic semiconductor crystals to have ordered orientation in the film, enhance contacts between crystals, improve mechanical strength and micro-machining property of the film, and give a high carrier mobility. The carrier mobility of weak oriented epitaxially grown film of the present invention is 0.32 cm2/Vs, which is 5 times as large as that of a vapor phase deposited film, and is similar to that of single crystal. The present invention is adapted to glass substrates and plastic substrates.

    摘要： The present application relates to a method of performing living cationic polymerization of monomers by supermolecular anion-binding catalysis. It uses various simple Bronsted acids or adducts thereof with a monomer as the cationic initiator, and various hydrogen bond donors as the catalyst for binding and dissociating counter anions dynamically, to living and controlled polymerize one or more cationically polymerizable monomers to form a homopolymer or a copolymer. In the present application, the hydrogen-bond donor can exert non-covalent anion-binding interactions to dynamically and reversibly activate dormant covalent bond under mild conditions, in turn to precisely control the equilibrium between dormant covalent precursors and active cationic species, thereby achieving the precise control of the polymer's molecular weight, distribution and end group structure, and solving the environment-unfriendly relevant problems in traditional metal-based Lewis acid catalysis, which include extreme low polymerization temperature, restrict anhydrous requirement of the reaction, strict purification requirement of the monomer and catalysis-initiating system, metal residue in polymer or the like.

    摘要： The present invention provides a chlorinated poly(propylene carbonate)/biomass composite material, comprising 3 wt % to 57 wt % of a chlorinated poly(propylene carbonate); 40 wt % to 94 wt % of a biomaterial; 2 wt % to 20 wt % of a rosin or a rosin derivative; 0 wt % to 1 wt % of an antioxidant; and 0 wt % to 5 wt % of a filler, wherein a sum of amounts of all components is 100 wt %. The chlorinated poly(propylene carbonate) functions as a binder, and plays an important role in the moisture resistance of the composite material. The rosin or the rosin derivative functions as a viscosifier and a lubricant, and can also improve the moisture resistance and mechanical property of the composite material. Under the synergistic effect of the above components, the composite material obtained in the present invention is excellent in both mechanical property and moisture resistance. Further, because the starting materials comprise a larger amount of biomass materials, the cost thereof is low, and because the starting materials contain no formaldehyde, benzene and the like, the material is environment friendly.
