A thin melt film forms locally at temperatures above the crystallite melting temperature (semicrystalline thermoplastics) or above the softening temperature (amorphous thermoplastics) (Fig.
The consensus of opinion is that modern day players are not necessarily better than their predecessors, but that the introduction of crystallite balls and better cloths has seen more consistent scoring.
We will employ specifically tailored molecules designed to leverage both thermodynamic and kinetic aspects of molecular organic semiconductor systems to direct and control crystalline packing, promote crystallite nucleation, compatibilize disparate phases, and plasticize inelastic materials.
s] is the crystallite size in nanometer, e is the wave length of x-ray beam, a is the broadening of diffraction line at half of its maximum intensity in radians, and [theta] is the Bragg's diffraction angle ([degrees]).
The material is Celanese's new Fortron ICE (Improved Crystallization Evolution) PPS, which is designed to crystallize at higher temperature than standard PPS, resulting in faster and more complete crystallization at lower temperatures and a finer, more uniform crystallite structure.
As the dimension of the Si crystallite shrinks to nm size, the band gap increases.
However, in most application fields, high-molecular-weight PLA with good thermal resistance is required [17, 19], Numerous efforts have been made on the synthesis of stereoblock poly (lactic acid) (sb-PLA), which will form more stable stereocomplex crystallite of high-molecular-weight PLA [14, 20-22],
