摘要:
Polymers are huge compounds made up of numerous monomers(repeated subunits).They have similar macro and micro properties,as well as electrical transport qualities,semiconductive capabilities,and optical features.With the advent of conductive polyacetylene,conductive polymers have gotten a lot of interest.These conductors have a wide range of electrical conductivity,which may be produced by doping,while being mechanically flexible and having a high thermal stability.Polymers may be created using a variety of methods,including chemical and electrochemical polymerization.With advancement in material stability and greater property control,an increasing variety of new applications are now being investigated.

摘要:
Interfacial solar-driven evaporation technique is an environmental friendly and cost-effective advanced approach for water purification using solar energy.Free energy sources are effectively utilized using the structural design of evaporators and functional materials.In this work,we have fabricated a solar-driven interfacial evaporation device with Banana Pseudo Stem(BPS)and a photothermal layer made up of PVA PDMS Carbon(PPC)is attached to it.High evaporation rate of 2.03 kg m^(−2) h^(−1) is achieved by the system under 1 sun illumination.Heat localization on interfacial surface,reflectance of photothermal layer,presence of micro-fluidic channels in BPS were studied using IR imaging,UV-DRS and SEM characterization techniques,respectively.Effective localization of interfacial temperature around 53°C and very low reflectance of photothermal layer substantiates high photothermal conversion efficiency of the device.The complete purification of water containing high concentration of Rhodamine-B dye using BPS is a novel and simple approach for water purification.This is an eco-friendly,cost-efficient novel approach in fabrication of interfacial solar-driven evaporation system with high evaporation rate for purification of water containing high concentration of organic dye.

摘要:
3D printing is nowadays used for many applications far beyond pure rapid prototyping.As tools to prepare custom-made objects which may be highly complex,different 3D printing techniques have emerged into areas of application where the mechanical,thermal,optical and other properties have to meet high requirements.Amongst them,applications for space,e.g.for microsatellites,make extreme demands regarding the stability under high temperatures.Nevertheless,polymeric 3D printed materials have several advantages for space application in comparison with metal objects.Here we thus investigate the impact of temperatures up to 85◦C and 185◦C,respectively,on typical 3D printing materials for fused deposition modeling or stereolithography(SLA)with inexpensive 3D printers.The materials are found to differ strongly in terms of mechanical properties and dimensional stability after the treatment at a higher temperature,with SLA resins and co-polyester showing the best dimensional stability,while acrylonitrile–butadiene–styrene and SLA resin after long UV post-treatment has the best mechanical properties.

摘要:
A well understanding about protein adsorption into charged polymer brushes is of importance in the elucidation of mechanism and important phenomena(such as “chain delivery”effect) in protein adsorption on polymer-grafted ion exchange adsorbents. In this work, quartz crystal microbalance with dissipation(QCM-D) was introduced to in situ investigate lysozyme adsorption on QCM sensors grafted with poly(3-sulfopropyl methacrylate)(pSPM) via atom transfer radical polymerization. It was achieved by analyzing frequency(f) and energy dissipation(D) shift simultaneously on pSPM-grafted sensors. The result showed that an initial decrease in ΔD was typical of lysozyme adsorption on pSPM-grafted sensor and more significant with an increase of chain length and grafting density. It was attributed to significant water release in the hydration layer of protein and polymer chains in lysozyme adsorption into pSPM brushes.On pSPM-grafted sensors with long and dense chains, furthermore, lysozyme transitioned from monolayer to multilayer adsorption and the maximum adsorbed amount was obtained to be 374.0 ng·cmamong all pSPM-grafted sensors in this work. The results in D-f plot further revealed that lysozyme adsorption into pSPM brushes increased the rigidity of adsorbed layer and little structure adjustment of adsorbed lysozyme. It was unfavorable for “chain delivery” effect for facilitated transport of adsorbed protein. This work provided valuable insight into protein adsorption in pSPM brushes and outlined a feasible approach to increasing mass transport in polymer-grafted ion exchange adsorbents.

摘要:
Smart membranes with tunable permeability and selectivity have drawn widespread attention because of their unique biomimetic characteristics.Constructed by incorporating various stimuli-responsive materials into membrane substrates,smart membranes could self-adjust their physical/chemical properties(such as pore size and surface properties)in response to environmental signals such as temperature,pH,light,magnetic field,electric field,redox and specific ions/molecules.Such smart membranes show great prospects in biomedical applications ranging from controlled drug release to bioseparation and tissue engineering.In this review,three controlled release models realized by different designed smart membranes are emphatically introduced,and then smart membranes for biological separation and controlled cell culture are introduced and discussed respectively.At last,the existing challenges of smart membranes for biomedical applications are briefly summarized,and future research topics are suggested.

摘要:
Thin-film flexible solar cells are lightweight and mechanically robust.Along with rapidly advancing battery technology,flexible solar panels are expected to create niche products that require lightweight,mechanical flexibility,and moldability into complex shapes,such as roof-panel for electric automobiles,foldable umbrellas,camping tents,etc.In this paper,we provide a comprehensive assessment of relevant materials suitable for making flexible solar cells.Substrate materials reviewed include metals,ceramics,glasses,and plastics.For active materials,we focus primarily on emerging new semiconductors including small organic donor/acceptor molecules,conjugated donor/acceptor polymers,and organometal halide perovskites.For electrode materials,transparent conducting oxides,thin metal films/nanowires,nanocarbons,and conducting polymers are reviewed.We also discuss the merits,weaknesses,and future perspectives of these materials for developing next-generation flexible photovoltaics.
