Model representation of filled polymers
Measurement Techniques, 1998We have investigated the mechanical properties and dielectric relaxation in polyamide-6 composites with fiber glass and mica. We propose a new model for filled polymers, assuming that the material consists of two interpenetrating continuous phases. The first phase is the polymer sorbed on the surface of the filler particles, mechanically stronger and ...

Porous polymers fill in the hole
Chemical & Engineering News Archive, 1999Using neatly arranged silica spheres as templates, researchers at Pennsylvania State University, University Park, have prepared organic polymers with ordered arrays of nanometer-sized holes [ Science , 283 , 963 (1999)]. The porous substances may be used to study cooperative materials properties like ferromagnetism, as separation media for large chiral

Ferrosilicochromium-Filled Polymer-Derived Ceramics
International Journal of Applied Ceramic Technology, 2011Rectangular green bodies fabricated from a granulated mixture of polymethylsilsesquioxane (PMS), ferrosilicochromium (FeSiCr), and SiC were cross-linked in a warm press at 240°C under a pressure of 9 MPa. The samples were then pyrolyzed at 950°C and subsequently heat treated at 1275°C in N2 atmosphere at pressures up to 5 MPa.

Thermal Ageing of Filled Polymers
British Polymer Journal, 1986AbstractThe rate of thermal ageing has been found to decrease when a polymer is adsorbed onto a filler. The retardation of this glassy state relaxation has been found to be dependent on the type and amount of filler present. Comparison with values for the glass transition temperature and melt rheology parameters shows that the same factors are ...

Experimental investigation and modeling of the dissolution of polymers and filled polymers
Polymer Engineering & Science, 1998AbstractDissolution of Polymers is important in various areas, including microlithography, controlled drug and herbicide/fertilizer delivery, and recycling. The dissolution rates of an oxetane polymer in ethyl acetate were obtained and well correlated with a quasi‐stationary dissolution model.

Preparation of filled polymer systems
1999In context with the preparation of filled polymer systems, there are three terms, namely, compounding, blending and mixing, which are often synonymously or interchangeably used and though various researchers have defined these terms, one is at times faced with the dilemma of terminology [1].

Rheology of Short Fibers Filled Polymers
1990In the present paper an account is given of the effects of matrix rheology, fiber length and concentration on the viscous properties of suspensions. The flow properties of concentrated fiber suspensions of different silicone oils and glass fibers were investigated by capillary viscometer.

Tensile strength of filled polymers
Journal of Polymer Science: Polymer Physics Edition, 1982AbstractA model is developed to predict the ultimate tensile strength of a particulate‐filled polymer which depends not only on the volume fraction of the filler and the elastic moduli of the two material phases, but also on the shape, size, and interfacial adhesion between the filler particle and the matrix.
