Pore structure characterization and gas transport property of the penetrating layer in composite membranes
Polymeric composite membranes have emerged as the leading technology in industrial gas separation fields for decades, but there are still several unsolved fundamental problems on the interface between layers in composite membranes, which hinders the development of membranes with better performance. The penetrating layer locating between the selective layer and…
New Approach to Optimize Mechanical Properties of the Immiscible Polypropylene/Poly (Ethylene Terephthalate) Blend: Effect of Shish-Kebab and Core-Shell Structure
Wang, Yingxiong; Mi, Dashan; Delva, Laurens; Cardon, Ludwig; Zhang, Jie; Ragaert, Kim
Improving the mechanical properties of immiscible PP/PET blend is of practical significance especially in the recycling process of multi-layered plastic solid waste. In this work, a multi-flow vibration injection molding technology (MFVIM) was hired to convert the crystalline morphology of the PP matrix from spherulite into shish-kebab. POE–g–MA was added…
Biodegradable PHB-Rubber Copolymer Toughened PLA Green Composites with Ultrahigh Extensibility
Yeo, Jayven Chee Chuan; Muiruri, Joseph K.; Tan, Beng Hoon; Thitsartarn, Warintorn; Kong, Junhua; Zhang, Xikui; Li, Zibiao; He, Chaobin
The sustainable biopolymer, poly(lactide) (PLA), has been intensely researched over the past decades because of its excellent biodegradability, renewability, and sustainability. The boundless potential of this sustainable biopolymer could resolve the adverse negative impact caused by the petroleum-based polymers. However, the inherent drawback of PLA such as brittleness, low heat…

Kizhisseri, Devi Renuka; Venugopal, Geethu; Lekshmi, C. Lalitha; Joseph, Kuruvilla; Mahesh, Sankarapillai
The process of utilizing organic molecules for tuning carbon nanomaterials has paved the way to a tremendous revolution in organic electronics, especially in developing field effect transistors, memory devices etc. Here we report the influence of insulating photochromic molecules on the conductance behaviour of carbon nanomaterials. Azobenzene derived from cardanol…
Disruptive effect of tocopherol oxalate on DPPC liposome structure: DSC, SAXS, and fluorescence anisotropy studies
Neunert, Grażyna; Tomaszewska-Gras, Jolanta; Siejak, Przemyslaw; Pietralik, Zuzanna; Kozak, Maciej; Polewski, Krzysztof
α-Tocopherol oxalate (TO), a tocopherol ester derivative, was investigated for its effect on the structural changes of fully hydrated 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) liposomes, as a function of concentration and temperature, by applying differential scanning calorimetry (DSC), small angle X-ray scattering (SAXS), and DPH fluorescence anisotropy methods. The DSC and DPH…
Deformation Mechanism of Poly(3-alkylthiophene) Studied by in Situ X-ray Scattering and Texture Analysis
Chen, Haiming; Su, Cui; Shi, Guangyu; Li, Xiaolu; Zhang, Xiuqin; Liu, Guoming; Wang, Dujin
Understanding the deformation mechanism of conjugated polymers is essential for developing flexible or stretchable electronic devices. In this work, the mechanical properties of poly(3-dodecylthiophene) (P3DDT) and poly(3-hexylthiophene) (P3HT) are measured at different temperatures, and the underlying deformation mechanism is explored by using in situ X-ray scattering and pole figure. It…
Programmable Multicomponent Self-Assembly Based on Aromatic Amino Acids
Xing, Pengyao; Phua, Soo Zeng Fiona; Wei, Xuan; Zhao, Yanli
Construction of integrated self-assembly with ordered structures from two or more organic building blocks is currently a challenge, since it suffers from intrinsic systematic complexity and diverse competitive pathways. Here, it is reported that aromatic amino acid building units can be incorporated into two- or three-component coassembly driven primarily by…

Wang, Jinfang; Wang, Peng; Wang, Qian; Mou, Hongyu; Cao, Bobo; Yu, Dongkun; Wang, Debao; Zhang, Suojiang; Mu, Tiancheng
In this study, a series of novel quasi-deep eutectic solvents (QDESs) based on organic base and thiourea (TU) and its derivatives were formed. Among them, DBU/TU or methylthiourea (MTU) could be used for the formation of the stable γ-Al2O3 colloid at quite a high concentration (0.6 mol %), which was…
Synthesis and characterization of nanoparticulate silica with organized multimodal porous structure impregnated with 12-phosphotungstic acid for its use in heterogeneous catalysis
Morales, Dolores M.; Frenzel, Romina A.; Romanelli, Gustavo P.; Pizzio, Luis R.
Mesoporous silica (MESSI) nanoparticles with ordered mesoporous frameworks were successfully obtained using the triblock copolymer P123 as the mesoporous template and agar as micropore former. The agar/TEOS ratio influences the specific surface area (SBET) and the micropore area (SMIC). The SBET values increase with the increment of the agar/TEOS ratio…
Intrinsic Tuning of Poly(styrene–butadiene–styrene)-Based Self-Healing Dielectric Elastomer Actuators with Enhanced Electromechanical Properties
Ellingford, Christopher; Zhang, Runan; Wemyss, Alan M.; Bowen, Christopher; McNally, Tony; Figiel, Łukasz; Wan, Chaoying
The electromechanical properties of a thermoplastic styrene–butadiene–styrene (SBS) dielectric elastomer was intrinsically tuned by chemical grafting with polar organic groups. Methyl thioglycolate (MG) reacted with the butadiene block via a one-step thiol–ene “click” reaction under UV at 25 °C. The MG grafting ratio reached 98.5 mol % (with respect to…
