An organic material for deposition that is used for dry deposition of an organic layer included in an organic photoelectric conversion element is provided in which the organic material contains an organic composition of the organic layer as a principal component, and a residual solvent content of the organic material for deposition is equal to or less than 3 mol %.

The invention discloses a wound protecting composition with bleeding-stopping and anti-bacterial functions and a preparation method of the wound protecting composition. The wound protecting composition comprises the following steps: (1) preparing an organic high molecular mixed solution; (2) adding one or two of chitosan and chitin into acetic acid, ethanol and water so as to prepare a bleeding-stopping and anti-bacterial material solution; (3) carrying out multi-spray-head electrostatic spinning so as to prepare a composite fiber material; and (4) drying the composite fiber material, removing residual solvents, and carrying out hot-press shaping, so as to prepare the wound protecting composition with the bleeding-stopping and anti-bacterial functions. The wound protecting composition disclosed by the invention has good bleeding-stopping and anti-bacterial effects, can be used for cleaning wounds and is good in biocompatibility; the water absorption rate is obviously increased, the bleeding-stopping time is greatly shortened, and the wounds are further protected.

The invention discloses SBS grafted odor-removing mattress spraying glue and a preparation method thereof. The SBS grafted odor-removing mattress spraying glue comprises, by weight, 10-15 parts of methyl isobutyl ketone, 5-10 parts of isopropyl formate, 10-20 parts of aromatic environment-friendly solvent oil, 15-25 parts of methyl cyclohexane, 10-18 parts of SBS elastomer, 0.1-0.5 part of BPO, 5-15 parts of MMA, 0-8 parts of BA, 0-3 parts of 2-HEMA, 1-3 parts of terminating agent, 10-15 parts of hydrogenated petroleum resin and 12-18 parts of hydrogenated rosin modified resin. The SBS grafted odor-removing mattress spraying glue has the advantages that the glue is colorless, transparent, high in adhesive force, resistant to yellowing, efflorescence, high temperature, oil and plasticizer, nontoxic, odorless and free of residues and is an ideal spraying glue choice for high-end mattress manufacturers, the glue is small in odor during spraying, a glue film is free of residual solvents and resin odor, pure white and transparent, and light-colored mattress fabric cannot polluted after glue spraying.
