“…Amongst which, PET is a widely used thermoplastic material because it has good creep properties, fatigue resistance, and dimensional stability 10) . However, our preliminary study revealed that the mechanical properties of PET were inferior to two commercial thermoplastic products, Erkodur and Biolon.…”

“…Poly(ethylene terephthalate)-glycol (PETG), a noncrystallizing amorphous copolymer of polyethylene terephthalate (PET), has good mechanical properties, formability, optical qualities, fatigue resistance, and dimensional stability. For these excellent properties, PET and PETG play an important role within the rapidly growing family of thermoplastic elastomers (TPE) and their applications can be found in almost all industrial branches [10][11][12] . Polycarbonate (PC) is a very durable material and can be laminated to make bullet-proof glass.…”

“…To obtain a useful product with a satisfactory level of cohesion, various structural considerations of the blend partners should be considered so as to obtain a blend that may be classified as miscible or mechanically compatible 20) . To date, a considerable amount of literature on polyester blends has been published: PETG/PET, PETG/LCP, PC/ABS, PC/PP, TPU/PVDF, TPU/PP, and TPU/PMMA 10,17,[21][22][23][24][25] . These studies showed that polymer blending was indeed an effective way to improve the mechanical properties of polymers, eventually culminating in a high-performance engineering material.…”

PETG/PC/TPU polymer blend was prepared by mechanical blending. The mechanical properties of modified PETG/PC/TPU blend were characterized using a universal testing machine, and results were compared against two commercial thermoplastic products -Erkodur and Biolon. Blending modification improved the properties of PETG/PC/TPU. When blending ratio (wt%) was 70/10/20, PETG/PC/TPU exhibited optimal mechanical properties which exceeded those of Erkodur and Biolon. Tear strength was 50.23 MPa and elongation at break was 155.99%. Stress relaxation rate was 0.0136 N/s after 1 hour, which was significantly slower than Erkodur and Biolon (p<0.05). Water absorption rate was 0.57% after 2 weeks, which was significantly lower than Erkodur and Biolon (p<0.05).

Despite successful fabrication of gecko-inspired fibrillar surfaces with strong adhesion forces, how to achieve an easy-removal property becomes a major concern that may restrict the wide applications of these bio-inspired surfaces. Research on how geckos detach rapidly has inspired the design of novel adhesive surfaces with strong and reversible adhesion capabilities, which relies on further fundamental understanding of the peeling mechanisms. Recent studies showed that the peel-zone plays an important role in the peeling off of adhesive tapes or fibrillar surfaces. In this study, a numerical method was developed to evaluate peel-zone deformation and the resulting mechanical behaviour due to the deformations of fibrillar surfaces detaching from a smooth rigid substrate. The effect of the geometrical parameters of pillars and the stiffness of backing layer on the peel-zone and peel strength, and the strong attachment and easyremoval properties have been analysed to establish a design map for bio-inspired fibrillar surfaces, which shows that the optimized strong attachment and easy-removal properties can vary by over three orders of magnitude. The adhesion and peeling design map established provides new insights into the design and development of novel gecko-inspired fibrillar surfaces.

“…The wide application and consequently higher production of flexible chain fiber forming polymers, in particular poly (ethylene terephthalate) (PET) is due to the possibility of the heat mechanical modification to obtain highly modular and high strength materials from them (Llana & Boyce, 1999;Bai et al, 2000;Dupaix & Boyce, 2005;Guzzato et al, 2009). PET is an essential engineering polymer with properties strongly depending of the degree of crystallinity and the perfection of crystal phase, too.…”
