    摘要： The purpose of the present invention is to provide: a masterbatch in which cellulose fibers are well dispersed in a rubber and the adhesion strength at the interface between the fibers and the rubber can be increased; and a simple method for producing the masterbatch.
    The present invention provides a masterbatch containing a polyolefin resin, cellulose fibers, and a silane coupling agent. The mass ratio of the polyolefin resin to the cellulose fibers to the silane coupling agent is preferably in a range of 25-74 : 20-55 : 2-55. The silane coupling agent preferably has a polysulfide structure.

    摘要： The present invention relates to a method for preparing a polymer solid electrolyte, and the polymer solid electrolyte prepared by freezing and thawing includes a cross-linked structure formed by a cross-linkable functional group, and the cross-linked structure includes (a) a cross-linkage between the cross-linkable functional groups, (b) a cross-linkage between the cross-linkable functional group and a solvent, and (c) a bond between the cross-linkable functional group and a lithium salt. Accordingly, even without using a separate plasticizer, crystallinity of the polymer solid electrolyte is reduced, and ionic conductivity can be improved. In addition, continuous process and mass production are possible.

    摘要： The present invention relates to the technical field of photoelectric materials, and in particular, to an alcohol dispersion of a conductive polyethylenedioxythiophene, and a method for preparing same and use of same. The present invention comprises a conductive polyethylenedioxythiophene and an alcohol, and the conductive polyethylenedioxythiophene comprises a polyethylenedioxythiophene cation and a fluorinated sulfonic acid ionomer counter anion. The present invention prepares a PEDOT alcohol dispersion by using an alcohol-dispersible highly fluorinated sulfonic acid ionomer as a counter anion to replace PSS, solving the hygroscopicity problem in conventional aqueous dispersions, and solving the problem that a conventional conductive aqueous dispersion of polyethylenedioxythiophene cannot be evenly applied on a hydrophobic surface due to high surface tension. The present invention has a simple synthesis process and is applicable to different substrates and different types of optoelectronic devices, thermoelectric devices, electrochromic thin films, and antistatic coatings, thus having broad prospects.
