In this study, a novel thermomechanical analysis (TMA) method was introduced to measure the exact polymer rebound amounts due to pressures removal after a thermo compression (TC) bonding process. Polymer resin was laminated between two silicon chips (7*7mm2), and then the compressive mode TMA measurement was done on the prepared samples. Constant compressive pressures were applied until the temperature...
Meanwhile the thermo-mechanical conditions during Friction Stir Welding (FSW) of metals have already been subject of extensive analysis and thoroughly discussed in literature, in which concerns the FSW of polymers, the information regarding this subject is still very scarce. In this work, an analysis of the material flow and thermo-mechanical phenomena taking place during FSW of polymers is performed...
In this paper, the morphology characteristic of tensile test fracture of nitrile rubber after aging at different temperatures for 24 hours was observed through scanning electron microscopy. Combined with the performance data of tensile test, the effect of aging temperature on the properties and fracture behavior of nitrile rubber was studied. The results show that the fracture of nitrile rubber includes...
Bulk heterojunction solar cells (BHJs) based on poly[N-9″-hepta-decanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)] (PCDTBT) can have internal quantum efficiencies approaching 100% but require active layers that are too thin to absorb more than ∼70% of the above bandgap light.[1] In this work, we demonstrate that PCDTBT films contain a high density of hole-traps, which correlate...
W obszernym wstępie omówiono zagadnienia związane z napięciem powierzchniowym (...) charakteryzujące tę wielkość od strony zarówno teoretycznej (równania stanu), jak i praktycznej (pośrednie oraz bezpośrednie metody wyznaczania ... w zależności od stanu skupienia badanego materiału). Część doświadczalna pracy dotyczy wpływu trzech istotnych czynników - morfologii (tabela 4), chropowatości (rys. 11-18)...
