    Long period of irradiated polyethylene strectched and thermally treated under different conditions has been studied by small-angle X-ray scattering.It is shown that long period reduces when the samples are stretched at room temperature. However it increases after thermal treatment. These results can be explained by the breakdown of crystalline structure at first and recrystallization afterwards.

    The change of glass structure in the manufacturing process of carbon impregnatedglass is studied by means of small-angle X-ray scattering (SAXS),with electron micro-scopy (EM) and large-angle X-ray scattering(LAXS) as supplementary tools in the paper. Carbon impregnated glass is used for making low temperature resistance thermome-ter. It is prepared by dipping porous high SiO_2 glass with acetophenone and then heat-treated in vacuum to decompose acetophenone to carbon,thus consolidating the glass.Theporous high SiO_2 glass is prepared by acid leaching of a heat-treated borosilicate glass. Experimental results indicate that owing to the presence of latent two-phase separationin the original borosilicate glass, the two-phase(the continuous rich Na_2O-B_2O_3 phase andthe rich SiO_2 phase) separation becomes more obvious after heat treatment.The avera-ge size of each phase as well as the pore size are estimated.From X-ray diffraction andEM observation,there exist amorphous continuous filaments of carbon and a trace of Sicrystallites in carbon impregnated glass.The average size of amorphous carbon is appro-ximately 100 A,as determined by SAXS.

    The bulk morphology and surface composition of biomedical devices of segmented polyether urethanes(SPEU) made hy the methods of solution molding are affected by the properties of solvents used. By using X-ray photoelectron spectroscopy(XPS or ESCA), small-angle X-ray scattering (SAXS), dynamic mechanical testing, and observations on surface contact angle, intrinsic viscosity and in vitro blood compatibility, the effects of solvents on the morphology of polymer chains, and the relationship between the microphase separation in the bulk and the surface composition of SPEU have been studied.Experimental results showed that(1) the solubilities of SPEU in solvents mainly depended on the solubilities of hard segments of SPEU; (2) the morphology of polymer chains of SPEU in solution and the microphase structures in the bulk were affected signifi cantly by the properties of solvents; (3)there were different periodic structures in the bulk of SPEU; the mean square radius of gyration and the distance between domains increased with the increase of hydrodynamic volume of SPEU in solution; (4) as the size of domain in the bulk increased, the amount of soft segments on the surface of SPEU also increased and the surface free energy decreased; (5)there was no linear relationship between the amount of soft segments and the blood compatibility on the surface of SPEU; (6) by regulating the properties of solvents, the bulk morphology and surface characteristics of SPEU could be controlled to a certain extent to improve the blood compatibility of SPEU

    由多嵌段聚醚型聚氨酯(SPEU)溶液成型加工所得制品的本体形态和表面化学结构受到配制溶液所用溶剂的显著影响。本文通过X射线光电子能谱(XPS或ESCA)、小角X—射线散射、(SAXS)、动态力学谱、表面接触角、特性粘度和离体血液相容性等实验,研究了多嵌段聚氨酯分子链在溶液中的形态与试样的微相分离和表面化学组成的关系。实验结果表明:(1)溶剂对SPEU的溶解性主要取决于它对SPEU分子链上硬段的溶解能力;(2)溶剂性质对溶液中SPEU分子链的形态和SPEU本体的微区结构有明显影响;(3)SPEU本体中具有不同层次的周期性结构;硬段微区均方回旋半径和微区间距随成膜时SPEU溶液中分子链的流体力学体积的增大而增大;(4)随着SPEU本体中硬段微区尺寸的增大,SPEU表面的软段含量增加,表面自由能减小;(5)SPEU本体的相分离程度、表面的软段含量和表面自由能与SPEU的血液相容性之间不存在简单的线性关系;(6)通过改变溶剂的性质,可以在一定范围内达到调节和控制SPEU的本体形态和表面特性的目的,以改善和提高其血液相容性。
