Apart from the tuning of the host-guest interactions, the elaboration of efficient optical devices also relies on the optimization of the matrix mechanical properties and thermal stability. This is clearly demonstrated in the development of hybrid materials for NLO, and especially second harmonic generation (SHG). These properties rely on their noncentrosymetric organization of organic chromophores in the condensed phase. Becanse incorporation in a silica... 

Phase Separation The process can directly fabricate a nanofiber matrix. Mechanical properties ofthe matrix can be arranged by polymer concentration. For specific polymers... 

In a natural fiber polymer composite, natural fiber is incorporated in a definite volume in the polymer matrix. Mechanical properties can be enhanced by increasing the fiber volume in a composite, but after a certain level, it may start decreasing due to the poor bonding between fiber and matrix. Oksman et al. [9] studied the effect of fiber loading with epoxy polymer. As shown in the Table 22.5, sisal fiber... 

Particle reinforced composite systems can be either large particle or dispersion strengthened. If a composite is reinforced by large particles (larger than 0.1 [xm and equiaxed, which are harder and stiffer than the matrix), mechanical properties are dependent on volume fractions of both components and are enhanced by increase of particulate content. Concrete is a common large particle strengthened composite where both matrix and particulate phases are ceramic materials.

As is known, composite materials are two- or multi-phase with well-defined interphase border. Such materials contain the reinforcing elements immersed into a polymeric, ceramic or metal matrix. Mechanical properties of composites depend on structure and properties of the interphase border. Phases of usual composite materials have micron and submicron sizes.

Water absorbs into the hydrophilic domains by attractive forces of water solvating the polar sulfonate salt. The hydrophilic domains swell doing work on the surrounding hydrophobic matrix (like blowing up a balloon). Water sorption is limited by the balance between the energy of solvation and the work to swell the matrix. Mechanical properties associated with swelling are very important in determining the water content of Nafion and hence the transport properties.
