However, traditional polyimide alignment films require high-temperature hard baking for at least 1 h to complete the cyclization polymerization.
In this study, the surface of polyimide alignment films was modified by ion beams to promote the transition.
Here we review ion-beam assisted deposition (IBAD) methods for inducing biaxial crystal alignment during film deposition.
The sequential alignment of film-sequences and script was structured in XML and the video player was realized in Adobe Flash.
The alignment of CNT film on the foils favors the formation of uniformly distributed layer of the protonated PANI on each CNT, which is possibly a result of controlled diffusion in the pseudo 1D channel and a confinement in the space between CNTs in the aligned CNT films.
Therefore, we also take (2D) GIWAXD image to investigate the P3HT chain alignment within nanograting film, as shown in Fig. 4.
Furthermore, the GIWAXD signals do not change for the P3HT nanograting films parallel or perpendicular to the direction of incident X-rays, as shown in Fig. 4b, c, indicating that chains alignment within nanograting film is also edge-on and displays a random distribution in the in-plane direction.
Photo-induced alignment of azopolymer films doped with SNPs was performed under irradiation of linearly polarized light at 442 nm.
This enhancement is due to the vertical alignment of graphene films with high in-plane thermal conductivity, which form a rapid and effective heat-transfer path.
MaSp1 and MaSp2 films processed using 80/20 MeOH/water stretch bath, and stretched to 2.5×, were also characterized using XRD, the images show an increase in β-sheet content and alignment from the films that were not stretched.
The present research aims to numerically investigate the effects of the slot injection configuration and the endwall alignment mode on the film cooling performance of the endwall.
