摘要:
A photorefractive (PR) polymer composite (310) is provided that includes a charge transporting polymer (CTP) matrix (311) and a photosensitizer (312) comprising a quantum dot (QD) material (314) with a first band gap (315) coupled to a nanoparticle material (317) with a second band gap (316) greater than the first band gap. The photosensitizer (312) is configured to generate a plurality of free charges (318) and to transfer the free charges to the CTP matrix (311) in response to an incident photon (320) on the PR polymer composite (310). An apparatus (500) is also provided, for writing holograms of 3D perspective views of an object from different directions within the PR polymer composite (310). A method (600) is also provided for forming the PR polymer composite.
摘要:
The invention related to a method of colouring portions of a tyre and to a tyre obtained by said method. The method includes: - forming a highly impermeable protective layer by depositing an aqueous emulsion on a part of the tyre to be coloured; and - depositing a coloured layer on the protective layer. The aqueous emulsion has at least a cross - linkable polymer base, and a surfactant of molecular formula (I) : (R 1 CONR 2 CHR 3 COO - ) n X n+ where R 1 is an aliphatic group C 6 -C 23 , R 2 is H or an aliphatic group C 1 - C 8 , R 3 is H or an aliphatic or aromatic group C 1 - C 8 , X is a metal cation, preferably an alkaline cation, and n is an integer of 1 to 3.

摘要:
Disclosed are catalyst systems, processes for making the catalyst systems, and processes for polymerizing at least one olefin monomer comprising ethylene to form a low-density polyethylene (LDPE). The polymerization process uses a catalyst system that can include: at least one diimine complex having the formula I:, wherein M is Ni, Pd, or Pt; a first activator such as an organoaluminum compound; and a second activator including a solid oxide chemically-treated with an electron withdrawing anion, such as fluoride silica-alumina. It was discovered that such the complexes could be activated in a manner to provide an active catalyst system that polymerized ethylene to form a low-density polyethylene (LDPE).
摘要:
Thermally conductive materials comprising an olefin block composite and a thermally conductive filler, where the thermally conductive filler is present in an amount sufficient to increase the thermal conductivity of the olefin block composite relative to the olefin block composite in its neat state. Such thermally conductive materials can be used in various articles of manufacture, such as a thermal interface material or a molded heat dissipation component.
