Thermal analysis of FeCl3-doped poly(3-butylthiophene) and poly(3-dodecylthiophene)

Optical properties and photo-oxidative degradation of regioregular poly(3-butylthiophene) films by spectroscopic ellipsometry

“…It was obtained from Sigma-Aldrich Chemical Co. Substrates were 1-mm-thick soda-lime glass plates obtained from Corning. The glass transition temperature, T g of P3BT is 75.4°C taken from the literature [22], so the annealing temperature for the P3BT films must be well above 75.4°C.…”

Stability of polarization in organic ferroelectric metal-insulator-semiconductor structures

“…Thermally activated relaxation processes of poly(3-alkylthiophene)s (P3-AT) such as P3HT have been well studied [12][13][14]42,139,147 throughout the last…”

“…From dynamic mechanical analysis (DMA) and DSC Chen et al [12][13][14] have identified three main relaxations in P3HT, referred to as α, β and γ. The α-relaxation (or glass transition) from −12 ○ C to 70 ○ C, centered at 26 ○ C, is attributed to twists in the main chains, formed by a chain of thiophene rings.…”
