EPT／BIIR橡胶密封材料制备及其性能

为了探索具备低水蒸气透过系数、低透气系数、低压缩永久变形以及良好耐老化性能的新型橡胶密封材料，鉴于影响并用胶性能的主要因素是共混相容性以及硫化速度，从实现并用胶优势互补角度出发，优选综合性能较好的三元乙丙橡胶（EPT）和溴化丁基橡胶（BIIR），开展了EPT／BIIR共混共硫化技术研究，并开展了DBPMH／HVA-2过氧化物硫化体系在EPT／BIIR并用胶中的应用研究。     

泡沫硅橡胶老化后的压缩性能

硅橡胶在贮存和使用过程中，常受到不同应力应变的作用，在其使用和贮存期间会产生一系列物理老化和松弛，导致其内部结构发生变化，从而引起各种性能尤其是力学性能的下降，当性能下降到一定程度时，吉卜赛材料允许使用极限，它就失去了使用价值，因此有必要对硅橡胶的库存和老化进行研究。

Self-assembly of Carboxyl Functionalized Polystyrene Nanospheres into Close-packed Monolayers via Chemical Adsorption

The polyacrylic acid functionalized polystyrene nanospheres were synthesized and self-assembled into irregular, densely packed monolayers in non-aqueous media. The polymer nanoparticles were chemically adhered to substrates. The morphologies of the resulting films were investigated. The impact of the volume fraction of alcohol in the mixed solvents on the particle adsorption and fabrication of nanosphere assembled films was examined.     

Studies on the Adsorption of Asymmetrical Triblock Copolymers by Scheutjens-Fleer Theory and Monte Carlo Simulation

The adsorption of asymmetrical triblock copolymers from a non-selective solvent on solid surface has been studied by using Scheutjens-Fleer mean-field theory and Monte Carlo simulation method on lattice model. The main aim of this paper is to provide detailed computer simulation data, taking A8-kB20Ak as a key example, to study the influence of the structure of copolymer on adsorption behavior and make a comparison between MC and SF results. The simulated results show that the size distribution of various configurations and density-profile are dependent on molecular structure and adsorption energy. The molecular structure will lead to diversity of adsorption behavior. This discrepancy between different structures would be enlarged for the surface coverage and adsorption amount with increasing of the adsorption energy. The surface coverage and the adsorption amount as well as the bound fraction will become larger as symmetry of the molecular structure becomes gradually worse. The adsorption layer becomes thicker with increasing of symmetry of the molecule when adsorption energy is smaller but it becomes thinner when adsorption energy is higher. It is shown that SF theory can reproduce the adsorption behavior of asymmetrical triblock copolymers. However, systematic discrepancy between the theory and simulation still exists.The approximations inherited in the mean-filed theory such as random mixing and the allowance of direct back folding may be responsible for those deviations.
