“…Cellulose and its derivatives are one of the promising natural materials due to their abundant, biorenewable, biodegradable and environmentally friendly characteristics . Importantly, these cellulose and derivatives have some similar moieties with PEIE and MSAPBS, which can emerge as potential materials for the interface layer of OSC devices.…”

The research on organic solar cells (OSCs) has made an immense progress over the last one decade because OSCs possess multiple advantages, such as light-weight, efficient, economical and large-area fabrication. [1][2][3] To date, the power conversion efficiency (PCE) at the laboratory scale has reached up to ≈16% by employing novel interfacial and photoactive materials. [4] Prior to the importance of photoactive layer, interfacial layer also plays a vital role to fabricate high-performance OSC by reducing the energy barrier at the interface and improving charge transfer. [5,6] However, it is usually impossible for the conventional single interlayer materials to satisfy all the requirements. In this regard, it is highly desirable to develop novel interfacial materials with suitable modification for highly efficient OSCs.To develop effective cathode interfacial materials, interface barrier should be minimized with improved electron mobility. Generally, interface barrier originates directly from the mismatch of the energy levels between the active layer and electrodes. Therefore, the key is to design suitable interfacial materials which can significantly reduce the interface barrier between the electrodes and active layer. In the past decades, numerous attempts have been made and significant progresses have been achieved for the cathode interface modification of OSCs. For example, few metallic salts, including LiF, CsF, and Cs 2 CO 3 , [7][8][9] have been integrated into OSCs to modify the interface and the devices exhibited enhanced efficiencies. However, the electron transfer ability of these metallic salts is low and these layers are thickness sensitive (<1 nm), which restrict their application on large scale. In this regard, some organic materials are also introduced for the interface modification of OSCs. Generally, organic materials are synthesized easily with high electron mobility and tunable bandgap energy. Some of them (poly [(9,9-bis(3′-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctyfluorene)], polyethylenimine, and polyethylenimine ethoxylated (PEIE)) were found to be effective interface modifiers with matched performance of these devices, compared to the devices using conventional interlayer materials (Ca/Mg). [10,11] However, OSC devices. However, the limited resources, high-cost, and non-ecofriendly nature of petrochemical-based interface materials restrict their commercial applications. Here, a facile and effective approach to prepare cellulose and its derivatives as a cathode interface layer for OSCs with enhanced performance from rice straw of agroforestry residues is demonstrated. By employing this carboxymethyl cellulose sodium (CMC) into OSCs, a highly efficient inverted OSC is constructed, and a power conversion efficiency (PCE) of 12.01% is realized using poly[(2,6-(4,8-bis(5-(2-ethylhexyl)-thiophen-2-yl)-benzo[1,2-b:4,5-b′] dithiophene))-alt-(5,5-(1′,3′-di-2thienyl-5′,7-bis(2-ethylhexyl)benzo[1′,2′-c: 4′,5′-c′]dithiophene-4,8-dione): 3,9-bis(2-methylene -((3-(1, 1-dicyanomethylen...

“…251 The PTh graft, in this fabrication strategy, caused a small decrease in the mechanical strength, while a great increase in electrical conductivity was observed. 255 A polymer derived from the family of PTh was used in fabrication of hybrid scaffolds. Planellas et al reported electrospun fibers made from poly(3-thiophene methyl acetate) (P3TMA) and an L-leucine-derived polymer containing ester, urea and amide groups as the supporting material.…”

“…Even though epoxy and PA6 matrices have comparable compressive strength and modulus, [58,[156][157][158] the remarkable differences in these properties between their composites is ascribed to the fact that CF is much stronger and stiffer than CelF. [159][160][161][162][163] The most important difference between epoxy and PA6 is that the former is brittle, whereas the latter is ductile. The compressive strength of E/CF is even greater than that of PP/WSF (Wheat Straw Fiber) (Figure 15), despite the fact that the fiber weight concentration in the latter composite is 20%.…”

Reinforcing polymers with particles and fibers has been a common strategy for decades, in order to make them suitable for high-demanding industrial applications. As composites often undergo dynamic loads, it is important to understand their behavior under such conditions. This review first classifies the types of polymer composites and then explains their failure behavior under tension and compression loading, followed by an overview of some of the experimental procedures used to characterize the polymer composites' dynamic mechanical performance. Afterward, the most significant findings in terms of the highstrain-rate compressive and tensile strength and modulus of polymer composites are thoroughly discussed. The results, available in the literature, on the mechanical properties of polymer composites under quasi-static conditions are also presented and compared with the high-strain-rate data. The differences are explained by discussing the changes in the structural configurations of polymer matrices under quasi-static and dynamic loads. Lastly, conclusions and future perspectives are given, with the intent of highlighting the most promising polymer composites that can be used for a wide variety of applications.
