Abstract: Disclosed are a doped colloidal metal oxide quantum wire and a preparation method thereof, a gas sensor, a gas sensor array, and use thereof, which relate to the technical field of gas sensors. In the preparation method, a main metal precursor, a doped metal precursor, an alcohol solvent, and a fatty acid surfactant are mixed, and a resulting mixture is subjected to a solvothermal reaction, to obtain the doped colloidal metal oxide quantum wire, wherein a main metal element in the main metal precursor is selected from Sn, Zn, W, In, Mo, Fe, Co, Ni, and Cu; a doped metal element in the doped metal precursor is selected from V, Nb, Ta, Cr, Mo, W, Mn, Fe, Co, Ni and Cu; the doped metal element is different from the main metal element; and the solvothermal reaction is performed at a temperature of 150-300° C.

Abstract: An impact modifier composition (IMC) is disclosed containing a polyolefin plastomer (POP) and a hydrogenated styrenic block copolymer (HSBC) represented by a general configuration selected from: S-S/EB, S-S/EB?, S-S/EB-EB?, S-S/EB?-EB, S-S/EB-S, S-S/EB?-S, S-EP-EB, S-EP-EB?, S-EB-EB?, S-EB?-EB, EB-S/EB-EB, EB?-S/EB-EB?, EB-S/EB?-EB, and mixtures thereof. Prior to hydrogenation, each block S is a polymer block of a vinyl aromatic monomer, each block EB is a polybutadiene block of 1,3-butadiene monomer having a vinyl content of <35 wt. %, each block EB? is a polybutadiene block of 1,3-butadiene monomer having a vinyl content of >35 wt. %, each block EP is a polyisoprene block of isoprene monomer, and each block S/EB and S/EB?, independently, is a copolymer block of a vinyl aromatic monomer and 1,3-butadiene monomer. The IMC can be used in thermoplastic polyolefin (TPO) compositions to improve impact resistance for various applications, including automobile parts.
