The vast rural drinking water sources along the Yellow River basin in Henan Province mainly come from the local high-salinity groundwater, which cannot be directly drunk. Zeolitic imidazolate framework-71/polyvinylidene fluoride hollow fiber composite membrane was applied to treat rural groundwater through membrane distillation technology. The variations of water quality parameters from 12 different rural regions after membrane distillation treatment were well analyzed and compared. Membrane separation performance for water samples from different regions during the membrane distillation process was investigated, including water flux and salt rejection. During a continuous 24-h membrane distillation process for the treatment of these water samples, hollow fiber membrane exhibits high solute retention rates (>99%) for salt ions, suspended solids and total dissolved solids, which are within the limits of national standards (GB 5749-2006), meanwhile membrane permeation water flux can remain stable. After the acid-cleaning for 180 min, all hollow fiber membranes can recover water flux well with a flux recovery rate above 98%. Even if the concentration ratio continued to increase, the water production rate of membrane distillation was basically maintained between 50% and 60%, which was obviously higher than the 30% of the reverse osmosis process. The economic analysis confirmed that the water production cost varied between US$0.45 and US$0.29/m3. With the extension of membrane service life, the specific membrane cost decreased rapidly in the first 6 years and then leveled off. The proposed vacuum membrane distillation process proved to be a promising water purification method for treating rural high-salinity groundwater.

“…The manufacture of polymeric thin films can be accomplished by using a variety of methods. Among these methods, phase inversion, interfacial polymerization, stretching, track-etching, additive manufacturing, and electrospinning are the methods that are most frequently employed. − Especially, electrospinning is a favorable method to fabricate nanofiber ultrathin films with a very little amount of solvent and polymer consumption . In the end, the fabricated nanofiber thin films have an interconnected pore structure with very high porosity and surface area, which is not efficient to be used for coating or protection purposes.…”

In this research, piezoelectric and heat-dissipating boron nitride nanotube (BNNT)/polyvinylidene fluoride (PVDF) nanocomposite thin films having superior properties for wearable sensing applications are introduced. Neat and 2.5 wt % (BNNT2.5)-and 5.0 wt % BNNT (BNNT5.0)-embedded PVDF thin films were prepared by first producing gel-like electrospun nanofibers followed by hot-rolling, respectively. The piezoelectric performance of BNNT5.0 was as high as 128.0 ± 5.4 mV under 300 kPa, while Neat and BNNT2.5 showed 9.9 ± 0.1 and 22.7 ± 8.8 mV, respectively. Furthermore, BNNT2.5 also presents almost 9 times and BNNT5.0 presents more than 3 times higher thermal conductivities of 0.89 ± 0.40 and 0.32 ± 0.10 W/mK, respectively, compared to Neat (0.10 ± 0.01 W/mK) and both present very high thermal resistance with no phase change up to 180 °C and less than 4% shrinkage even at 200 °C, while Neat begins melting at 120 °C. BNNT2.5 and BNNT5 showed a high water-repelling property and mechanical strength as well. Tensile strengths and elongation for BNNT2.5 and BNNT5.0 were 18.1 MPa with 52.1% and 21.2 MPa and 34.0%, respectively. They both showed a low moisture absorption property with high water repellence with stable and hydrophobic water contact angles (92.2°with only 0.4°c hange for BNNT2.5 and 103.6°with 2.4°change for BNNT5.0 in 30 s), while Neat was in the hydrophilic region. Consequently, BNNT/PVDF films with highly enhanced piezoelectric-sensing and heat-dissipating properties and mechanical, thermal, and moisture resistance can be applicable for various wearable sensing environments.

Surface Engineering of a Bioartificial Membrane for Its Application in Bioengineering Devices

Membrane technology is playing a crucial role in cutting-edge innovations in the biomedical field. One such innovation is the surface engineering of a membrane for enhanced longevity, efficient separation, and better throughput. Hence, surface engineering is widely used while developing membranes for its use in bioartificial organ development, separation processes, extracorporeal devices, etc. Chemical-based surface modifications are usually performed by functional group/biomolecule grafting, surface moiety modification, and altercation of hydrophilic and hydrophobic properties. Further, creation of micro/nanogrooves, pillars, channel networks, and other topologies is achieved to modify physio-mechanical processes. These surface modifications facilitate improved cellular attachment, directional migration, and communication among the neighboring cells and enhanced diffusional transport of nutrients, gases, and waste across the membrane. These modifications, apart from improving functional efficiency, also help in overcoming fouling issues, biofilm formation, and infection incidences. Multiple strategies are adopted, like lysozyme enzymatic action, topographical modifications, nanomaterial coating, and antibiotic/antibacterial agent doping in the membrane to counter the challenges of biofilm formation, fouling challenges, and microbial invasion. Therefore, in the current review, we have comprehensibly discussed different types of membranes, their fabrication and surface modifications, antifouling/ antibacterial strategies, and their applications in bioengineering. Thus, this review would benefit bioengineers and membrane scientists who aim to improve membranes for applications in tissue engineering, bioseparation, extra corporeal membrane devices, wound healing, and others.
