A hydrogenation catalyst is provided. The hydrogenation catalyst has a nanonickel carrier, and noble metal nanoparticles selected from Pd, Pt, Ru, Rh, or a mixture thereof, which are mounted onto the nanonickel carrier. Moreover, a method of manufacturing a hydrogenation catalyst is provided, and has steps of (1) preparing an aqueous solution containing nickel ions; (2) adding a first reducing agent in the aqueous solution containing nickel ions to form a reactant solution; (3) applying a magnetic field to the reactant solution for a first duration to obtain a nanonickel carrier; (4) preparing a noble metal solution; and (5) placing the nanonickel carrier in the noble metal solution for a second duration so that noble metal nanoparticles are mounted onto the nanonickel carrier.

An extended film and a manufacturing method thereof are provided. The extended film includes a poly(lactic acid) and a block copolymer, wherein the block polymer includes a first block, a second block and a third block that connected with each other by chemical bonds. The extended film is formed by steps of mixing poly(lactic acid) and the block copolymer to form a mixture, compressing the mixture to form a board body and extending the board body to form an extended film, thereby forming an extended film having properties of high thermal-resistance and high transparency, the film thus obtained is applicable for packaging use.

Extended film and the manufacturing method thereof

A random amorphous copolyester is synthesized by using diacid monomers and diol monomers. The random amorphous copolyester has a structure of the formula (I): wherein R, Ris an aromatic or aliphatic monomer, A is 0-0.8, B is 0-0.8, C is 0-1, D is 0-1, E is 0-0.8, F is 0-0.8, C+D&#x3c;0.2 and A+B+E+F&#x3c;0.8. The diacid monomer comprises TPA and an aromatic or aliphatic diacid monomer, the diol monomer comprises EG, 1,3 and 1,4-CHDM, and an aromatic or aliphatic diol monomer.
