A method to evaluate mechanical performance of thin transparent films for flexible displays

Electroplating to visualize defects in Al2O3 thin films grown using atomic layer deposition

“…Defect contrast enhancement techniques have been used in the past for defect visualization. Sobrinho et al [11] and Sonia et al [15] used oxygen plasma etching to undercut the barrier films on polymer substrates deposited by physical vapor deposition or chemical vapor deposition. The etching renders the defects visible in transparent silicon-oxides and silicon-nitrides thin films.…”

Evaluation of toughness by finite fracture mechanics from crack onset strain of brittle coatings on polymers

“…Reactive ion etching appears promising as a possible means for accomplishing it in the case of polymer substrates [20,23,27,28]. Alternatively, the coating has to be pre-cracked (see e.g.…”

“…Experimental evidence is appearing that coating crack propagation may be more complicated than suggested by the mentioned models; it can involve a quasi-stable growth of cracks within a narrow strain range [17][18][19][20]. Such behavior is likely to result from a local, small-scale heterogeneity in the resistance to crack propagation [21] and/or residual stress field [19].…”

Preparation and characterization of NIR cutoff antimony doped tin oxide/hybrid silica coatings

“…Antimony doped tin oxide (ATO) is a kind of well-known optically transparent, infrared light insulating and electrically conducting oxide, which is commonly used in heatinsulating films [4][5][6][7][8][9]. What is more, to the best of our knowledge, when conventional coatings are added to flexible, relatively soft plastic substrates, it is easy resulted in poor adhesion or mechanical failures [10]. Therefore, to overcome these shortcomings, organic/inorganic hybrid composite coatings may be the appropriate solution [11].…”
