“…The organic pendent groups can be designed to achieve the desired affinity with the host polymeric matrix [1,2]. Using POSS in polymer based nanocomposites is a promising issue for the design 561 Structure-properties relationships of polyhedral oligomeric silsesquioxane (POSS) filled PS nanocomposites of materials with high-performance in several applications [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] such as low-dielectric applications [6], biomaterials for cardiovascular [14] and dental implants [16], organic solar cells [17], flame resistant nanocomposites [18,19], optical limiting [20], etc. An important feature of the POSS formulation is their one-pot preparation, i.e.…”

Abstract. The polyhedral oligomeric silsesquioxane (POSS) additivated polystyrene (PS) based nanocomposites were prepared by melt processing and the structure-properties relationships of the POSS-PS systems were compared to those of the neat PS. In order to investigate the effect of these structural parameters on the final properties of the polymer nanocomposites, five different kinds of POSS samples were used, in particular, POSS with different inorganic cage and with different organic pendent groups. The rheological investigation suggests clearly that the POSS acts as a plasticizer and that the processability of the PS was positively modified. The affinity between the POSS samples and the PS matrix was estimated by the calculated theoretical solubility parameters, considering the Hoy's method and by morphology analysis. Minor difference between the solubility parameter of POSS and the matrix means better compatibility and no aggregation tendency. Furthermore, the POSS loading leads to a decrease of the rigidity, of the glass transition temperature and of the damping factor of the nanocomposite systems. The loading of different POSS molecules with open cage leads to a more pronounced effect on all the investigated properties that the loading of the POSS molecules with closed cage. Moreover, the melt properties are significantly influenced by the type of inorganic framework, by the type of the pendent organic groups and by the interaction between the POSS organic groups and the host matrix, while, the solid state properties appears to be influenced more by the kind of cage.

Abstract. POSS with cage-like hybrid molecules composed of silicon and oxygen has raised great interests of materials researchers owing to its excellent mechanical and thermal properties, such as tensile strength, tensile modulus and glass transition temperature Tg. And it has been widely used in electronics, automotives and multiple applications. The four basic manufacturing advances on POSS reinforced resin matrix composites were revealed in this paper and the corresponding conclusions were given. The advances concluded that POSS as reinforced phase could to some extent improve the mechanical and thermal properties of nanocomposites.

“…This recognition emerges from the fact that these resins have several desirable properties, such as outstanding mechanical strength, heat resistance, dimensional stability, flame resistance and low generation of smoke, as well as, high resistance against various solvents, acids and water. [3][4][5][6] Their composites occupy a major market in thermostructural application in the aerospace industry due to their excellent properties and relative low cost. 7,8 a-Al 2 O 3 is the hardest form of alumina, which is usually used as a filler to improve the mechanical and thermal properties of polymers.…”

An environmentally friendly phenolic resin/Al 2 O 3 hybrid composite was prepared. Al 2 O 3 particles were pretreated with a silcane coupling agent, then the mixture of paraformaldehyde and treated Al 2 O 3 was grinded with ball crusher for several hours, and added during the phenolic resin polymerization process, finally got the hybrid composite. The kinetic parameters of thermal degradation were calculated by the methods of Kissinger, Flynn-Wall-Ozawa and Crane. The thermal degradation activation energy of environmentally friendly phenolic resin/Al 2 O 3 hybrid composite is approximate three times of pure phenolic resin. The results show that the heat resistance is obviously improved.
