More in-depth research papers PLA / TiO 2 Organic-Inorganic Hybrid Materials and hybrid materials anticoagulant properties . Lactic acid as raw materials , stannous octoate as a catalyst for the preparation of poly lactic acid ( PLA ) ; PLA, titanate, tetra-n- butyl (TBT) as raw material , the use of the sol-gel method PLA / TiO 2 Organic inorganic hybrid materials , and were characterized by FT-IR, XPS , and other means of testing of the relevant product . The results show that the hybridization reaction , the PLA with a titanium sol , of PLA with TiO 2 between the components is based on the Ti-OC bonding . Compared with pure PLA , the TiO 2 < / sub> introduced to improve the anti- clotting properties of polylactic acid , and the as TiO 2 content of change varies TiO 2 Add 4wt% . In the PLA / TiO 2 organic-inorganic hybrid materials preparation process , the introduction of the rare earth elements Sm, Sm doped PLA / TiO 2 organic-inorganic hybrid materials were prepared . PLA Sm doping 2 organic-inorganic hybrid anticoagulant properties of the material is increased with the increase of Sm content , the maximum downward trend has emerged , Sm amount of 0.6wt% / TiO of the best effect .
