“…The former has been the subject of significant study 1 3 4 5 for typically low peeling speeds of O (10) cm/s due to the production of a characteristic sound audible to the human ear, whilst the latter has been less studied. For extremely low peeling speeds ( O (10 −5 ) m/s), a sawtooth pattern was observed at the peeling front 6 .…”

We investigate the generation of the screeching sound commonly heard during tape peeling using synchronised high-speed video and audio acquisition. We determine the peak frequencies in the audio spectrum and, in addition to a peak frequency at the upper end of the audible range (around 20 kHz), we find an unexpected strong sound with a high-frequency far above the audible range, typically around 50 kHz. Using the corresponding video data, the origins of the key frequencies are confirmed as being due to the substructure “fracture” bands, which we herein observe in both high-speed continuous peeling motions and in the slip phases for stick-slip peeling motions.

“…This was stimulated by advanced optical and other methods of investigation of AS and processes taking place at the interface bound aries. Using probe microscopes, the sticking-detach ment processes, deformation of polymeric films, roughness of the substrate surface, microrelief struc ture, dependences of AS on the loading rate, and adhesive thickness were estimated at the atomic level [73][74][75][76]. Scanning microscopes (STM) allow one to reveal the presence of impurities-the smallest parti cles remaining on the substrate [45].…”

“…[1][2][3][4][5][6][7][8][9] Kaelble [1] reported that the stringiness disperses applied stress concentrated at the tip of peeling by indicating generated stress. Urahama [2] identified two types of stringiness shape dependent on the backing materials of the pressure-sensitive adhesive (PSA) tape: sawtooth-shaped and honeycomb-shaped.…”

The formation of sawtooth-shaped stringiness during 90°peeling was investigated using crosslinked poly(n-butyl acrylate-acrylic acid) and poly(2-ethylhexyl acrylateacrylic acid) random copolymers with an acrylic acid content of 5 wt.% and different crosslinking degrees as pressure-sensitive adhesives (PSAs). The gel fraction was measured by toluene extraction of PSA, and it increased with crosslinker content for both systems. The observed stringiness was sawtooth-shaped, but there were three different types; both the typical sawtooth shape and the frame formed at the front tip with interfacial failure, and the sawtooth shape formed with cohesive failure. The change in the stringiness shape was affected strongly by the gel fraction of PSA. The peel rate under constant peel load was measured and revealed that the peel rate was lowest upon formation of the front frame type. A good relation was found between peel rate and peel strength, with a greater peel strength upon formation of the front frame type. The concentrated stress at the peeling tip is released by progress of peeling and deformation of the adhesive layer (stringiness) for no frame type. On the other hand, the sufficient interfacial adhesion delays the progress of peeling, and the applied larger stress causes cavitation in the PSA layer for front frame type. The formed cavity grows and the front frame type formed as a result. That is, internal deformation occurred preferentially over peeling. In order to improve the peel strength, the front frame type is the most useful stringiness shape.
