Trifluoromethyl and benzyl ether side groups containing novel sulfonated co-poly(ether imide)s: Application in microbial fuel cell

Kumar, Anaparthi Ganesh; Saha, Sayantani; Komber, Hartmut; Tiwari, Bikash Ranjan; Ghangrekar, Makarand M.; Voit, Brigitte; Banerjee, Susanta

A new diamine monomer namely 4,4′-((2′,5′-bis(benzyloxy)-3,3′'-bis(trifluoromethyl)--4,4′'-diyl)bis(oxy))dianiline (TADBE) was prepared. A series of sulfonated co-poly(ether imide)s was synthesized using this diamine as one of the co-monomers along with 4,4′-diaminostilbene-2,2′-disulfonic acid (DSDSA) on reaction with a six-membered dianhydride, 1,4,5,8-naphthalene…

Restricting Effect of Solvent Aggregates on Distribution and Mobility of CuCl2 in Homogenous Catalysis

Wang, Yongtao; Wang, Guanqi; Yao, Jia; Li, Haoran

Extensive experimental and theoretical studies have proven the existence of solvent aggregates in alcohols, and some attempts have been made to explore the uneven distribution of solutes. Here, we studied the distribution and mobility of CuCl2 in 3-hexanol and ethanol and investigated the aerobic oxidation of 2,3,6-trimethylphenol under these systems.…

Broadening the optical absorption of organic photovoltaic (OPV) materials by enhancing the intramolecular push-pull effect is a general and effective method to improve the power conversion efficiencies of OPV cells. However, in terms of the electron acceptors, the most common molecular design strategy of halogenation usually results in down-shifted molecular…

Chalard, Anaïs; Joseph, Pierre; Souleille, Sandrine; Lonetti, Barbara; Saffon-Merceron, Nathalie; Loubinoux, Isabelle; Vaysse, Laurence; Malaquin, Laurent; Fitremann, Juliette

In this work, we describe how a simple single low molecular weight gelator (LMWG) molecule – N-heptyl-D-galactonamide, which is easy to produce at the gram scale – is spun into gel filaments by a wet spinning process based on solvent exchange. A solution of the gelator in DMSO is injected…

Sustainable network polymer via dynamic metal ionic crosslinks

Wang, Yanjun; Lei, Yuan; Zhou, Changlin; Wu, Bo; Jiang, Yuanyuan; Lei, Jingxin

Incorporating reversible dynamic linkages into the polymer networks endows traditional thermosets with recyclability and reprocessability. However, the facile preparation of recyclable polymer networks with suitable stability and acceptable cost is still a challenge. Among various dynamic linkages, ionic bonds promise a rational dynamic linkage in virtue of suitable stability and…

Organic acids interacting with block copolymers have broadened the window that retains isoporous structures

Zhu, Guo-Dong; Yin, Yu-Rong; Li, Zhen-Nan; Qiu, Ya-Yu; Yi, Zhuan; Gao, Cong-Jie

Evaporation is significantly important for the preparation of isoporous membranes from self-assembly and non-solvent induced phase separation (SNIPS). Unfortunately, the time of solvent evaporation that retains isoporous structures is usually rather short, which causes many challenges to fabricate membranes with repeatable and controllable isoporous structures. In the current work, we…

Effect of side methyl from mixed diamine chain extenders on microphase separation and morphology of polyurethane fiber

You, Gexin; Wang, Jiaqi; Wang, Chunyan; Zhou, Xulin; Zhou, Xiuwen; Liu, Lina

Polyurethane fiber (PUF) can be used as self-adaptive material in the field of nuclear physics and its properties depended on the molecular structure. To explore the effect of side methyl on its degree of microphase separation (DPS) and morphology for PUF, ethanediamine and 1,2-propylene diamine with different molar ratio were…

Osta, Oriana; Bombled, Marianne; Partouche, David; Gallier, Florian; Lubin-Germain, Nadège; Brodie-Linder, Nancy; Alba-Simionesco, Christiane

We propose a method to enhance lysozyme trapping and supported-Copper catalysis when confined in organosilica materials. The direct synthesis presented here allows the control of the silica surface hydrophobicity by uniform introduction of methyl or phenyl groups. As a result, the lysozyme trapping is observed to be 3.2 times more…

Precise Self-Assembly of Nanoparticles into Ordered Nanoarchitectures Directed by Tobacco Mosaic Virus Coat Protein

Zhang, Jianting; Zhou, Kun; Zhang, Yejun; Du, Mingming; Wang, Qiangbin

Self-assembly guided by biological molecules is a promising approach for fabricating predesigned nanostructures. Protein is one such biomolecule possessing deterministic 3D crystal structure and peptide information, which acts as a good candidate for templating functional nanoparticles (fNPs). However, inadequate coordination efficacy during the establishment of interfacial interactions with fNPs…

Simultaneously enhancing of wear-resistant and mechanical properties of the thermoplastic polyurethane (TPU) is important for its wider application. Herein, fluorinated graphene (FG) was proposed and respectively functionalized by two amine-terminated molecules: aliphatic poly (oxypropylene) diamine (D230) (compatible with soft segment (SS) of TPU), and aromatic phenylamine (PA) (compatible with…
