The new worldview of nonlinear polymer theology: its phenomenological foundation and significance for polymer processing
we will review the discoveries in the field of nonlinear theology of entangled polymers since 2006 when it was first reported that synthetic polymers could undergo inhomogeneous shear beyond the stress overshoot during startup shear and show non-quiescent relaxation after a large step strain [1-2] In the past decade, we have attempted to develop a realistic understanding to address the follo...

On the elasticity of polymer fluids
关键字：fluid elasticity polymer fluids die swell inlet pressure drop References
It was showed in literatures that polymer fluids (as melts or solutions) which have similar viscosity but different elasticity, their theological and processing behaviors were widely divergent.The measure method and norm for fluid elasticity are not a circumstance to fluid viscosity. The physical quantities to describe of fluid elasticity in literatures were various [1-2] There are distinguishe...

Highly Efficient 2D-Conjugated Benzodithiophene-Based Photovoltaic Polymer with Linear Alkylthio Side Chain
关键字：BDT, Polymer solar cells, 9.5
Starting from two e?cient photovoltaic polymers, a novel two-dimensional conjugated BDT-based polymer, PBDT-TS1 was designed, synthesized by introducing linear side chain and a high PCE of 9.48% was achieved by PBDT-TS1:PC71BM-based PSC evaluating with the simple conventional device. More importantly, due to the high starting point acquired in simple conventional...

How the linkage positions affect the performance of bulk-heterojunction polymer solar cells
关键字：bulk-heterojunction polymer solar cells, linkage positions
Two new alternating copolymers. PCT-10,13-BPz (P1) and PCT-2,7-BPz (P2), which were constructed from the same monomers and only different in the connecting points, were synthesized via Suzuki coupling reaction. The UV-vis absorptions, thermal stability, energy levels, field-effect carrier mobility and photovoltaic characteristics of the two copolymers were systematically evaluated to understand th...
