Polymer blends and alloys have more complex behavior in the presence of fillers than the binary mixtures of polymer and filler. The same factors, such as filler distribution, filler-matrix interaction, filler-matrix adhesion, particle orientation, nucleation, chemical reactivity, etc. have influence on properties, but this influence is complicated by the fact that there are two or more polymers present which compete for the same filler particles. These complex interactions result in many interesting phenomena discussed below. 

Technical Meeting - The Annual Technical Meeting begins on Sunday, February 26. Over 150 technical presentations. Topics include Structural Adhesives, Soft Adhesives, Particle Adhesion, Contact Mechanics, Mechanics of Failure, Bio-inspired and Green Adhesives, Single Molecule Adhesion, and many more.

Since, from the first law of adhesion, particles always adhere, the natural state of particulate materials is aggregated as in Fig. 10.1 (a), with each particle stuck fast to its neighbors. However, when the particles become contaminated with liquid, the second law of adhesion applies and the adhesion is reduced. In certain circumstances, this reduction in adhesion proceeds so far that the particles remain separate or dispersed in the contaminating medium, as in Fig. 10.1(b). Such bizarre behavior is a challenge to the theorist because it seems to go against the basic laws of adhesion. The purpose of this chapter is to show that several complex mechanisms cause the particles to behave strangely. The most important mechanism is Brownian movement, followed by electric charging, followed by adsorption of polymer molecules at the surface. 

The various ways in which epoxies can be toughened by introduction of a secondary phase are discussed in separate articles Toughened epoxide adhesives particle formation prior to cure, Toughened epoxide adhesives precipitation during cure and Toughened epoxide adhesives blend synergy.

The increase in particle adhesion to an oily surface may be affected by impurities that are present in the liquid medium. After evaporation of the liquid, these impurities tend to increase the adhesive interaction between particles and painted surfaces. In an evaluation of such increases in particle adhesion, particles were deposited on chlorinated PVC enameled surfaces, together with a drop of liquid. The particles in the liquid drop remained on the surface after evaporation of the liquids the particle adhesion, however, was found to be different from the adhesion of the same dust in air. 

Encapsulization n. The enclosure of adhesive particles with a protective film that prevents them from coalescing until such time as proper pressure or solvation is applied. 

A total of four types of recycled fiber plus two types of virgin fiber were used as the reinforcement in concrete. Three recycled fibers were obtained from disposed tires and one from carpet waste. The tire fibers included two types of tire fabrics composed of polymeric tire cords, tire-rubber strips which were the main component of tires, and tire steel fibers which were the radial steel reinforcement of tires. The fibers from carpet waste contained backing fibers (nsually polypropylene), latex adhesive particles, and a small amount of face fibers. In addition, hooked end steel fibers and FiberMesh polypropylene fibers were also used as virgin fibers for comparison. Recycled fiber volume fractions in each composite were fixed at 2% except that the tire steel fiber and the virgin fibers (steel fiber and FiberMesh) were used at a 1 vol%.
