Vapochromic led

A sandwich device was prepared by electrodeposition of an insoluble layer of oligomerized tris(4-(2-thienyl)phenyl)amine onto conducting indium-tin oxide coated glass, spin coating the stacked platinum compound, tetrakis(p-decylphenylisocyano)platinum tetranitroplatinate, from toluene onto the oligomer layer, and then coating the platinum complex with aluminum by vapor deposition. This device showed rectification of current and gave electroluminescence. The electroluminescence spectrum ( lambda max=545 nm) corresponded to the photoluminescence spectrum of the platinum complex. Exposure of the device to acetone vapor caused the electroemission to shift to 575 nm. Exposure to toluene vapor caused a return to the original spectrum. These results demonstrate a new type of sensor that reports the arrival of organic vapors with an electroluminescent signal. The sensor comprises (a) a first electrode; (b) a hole transport layer formed on the first electrode; (c) a sensing / emitting layer formed on the hole transport layer, the sensing / emitting layer comprising a material that changes color upon exposure to the analyte vapors; (d) an electron conductor layer formed on the sensing layer; and (e) a second electrode formed on the electron conductor layer. The hole transport layer emits light at a shorter wavelength than the sensing / emitting layer and at least the first electrode comprises an optically transparent material.

Flame-retardant ceramic composite material and preparation method thereof

The invention discloses a flame-retardant ceramic composite material which comprises the following components in parts by weight: 100 parts of polyolefin, 0-100 parts of silicone rubber, 1-100 parts of silica, 0-30 parts of silicone oil, 0.00001-10 parts of platinum complex or platinum compound calculated based on platinum, 0-10 parts of coupling agent, 0-100 parts of flame retardant, 1-250 parts of porcelain powder, 0-10 parts of antioxidant, and 0.01-10 parts of vulcanizing agent. The materials are mixed in a kneading machine, the materials are added into the kneading machine through vacuumizing and then uniformly mixed so as to obtain bulk ceramic rubber, and after being cooled, the cooled rubber is subjected to open milling by adding the vulcanizing agent so as to obtain the flame-retardant ceramic composite material. The flame-retardant ceramic composite material disclosed by the invention is easy to process and low in production cost, and can be ablated into a ceramic shell so as to protect a burnt object from being damaged. Because a platinum complex or a platinum compound is added in the flame-retardant ceramic composite material disclosed by the invention, the sintering temperature of the flame-retardant ceramic composite material can be reduced, the reaction speed of preparation can be increased, the production efficiency is improved, and the production cost is lowered.

The invention discloses flame-retardant ceramic silicone rubber. The flame-retardant ceramic silicone rubber contains the following materials in parts by weight: 100 parts of silicon rubber, 1-100 parts of silica, 0-30 parts of silicone oil, 0.00001-10 parts of platinum in platinum complex or platinum compound, 0-10 parts of coupling agent, 1-100 parts of flame retardant, 1-150 parts of ceramic powder and 0.01-10 parts of vulcanizing agent. A preparation method of the flame-retardant ceramic silicone rubber comprises the steps of milling the materials in a kneader, vacuumizing, adding into the kneader, milling uniformly to form lumpish ceramic rubber, cooling, adding the vulcanizing agent, and carrying out open milling, thereby obtaining the flame-retardant ceramic silicone rubber. The flame-retardant ceramic silicone rubber is easy to process and low in production cost and can be ablated into a ceramic-like shell, so as to protect an ablated object from being damaged. According to the flame-retardant ceramic silicone rubber disclosed by the invention, due to the addition of the platinum complex or platinum compound, the sintering temperature for the flame-retardant ceramic silicone rubber can be lowered, and the reaction rate of preparation can be increased, so that the production efficiency is increased, and the production cost is reduced.
