“…When Figure 2 are examined in detail, it is seen that the 5 wt.% additive has a more homogeneous distribution within the fiber structure. This result can be interpreted as the distribution of CLN particles contributes to both the increase in the hard segment structure of the fibers and the formation of hydroxyl groups between the fibers 57 . This interpretation is also in agreement with the results obtained from FTIR data (Table S1).…”

The treatment of skeletal muscle, which lost its function with damage or trauma with autologous muscle tissue transfer, is a very problematic approach.Hence, it is critical to develop materials that are mimicking muscle tissue mechanical behaviors and allowing cell adhesion. Polyurethanes (PUs) are one of the most common polymers in tissue engineering applications and skeletal muscle regeneration due to their elasticity and mechanical flexibility. Clinoptilolite (CLN) is a hydrated alumina silica crystal based biocompatible material that numerous positive effects on animal and human health. Here, we report the synthesize of flexible membranes based on clinoptilolite (CLN) doped thermoplastıc polyurethane (TPU) nanofiber network to be used in the field of skeletal muscle regeneration. We primarily evaluated their ability to mimic skeletal muscle by determining their mechanical properties and cell adhesion rates. We observe that cell adhesion and proliferation increased with the increase of CLN contribution. Young modulus (E Y ) values of pure TPU, 5 and 10 wt.% CLN-doped TPU fibers are 3.66, 2.37, and 1.85 MPa, respectively. Mechanical elongations at break of pure TPU, 5 and 10 wt.% CLN-doped TPU fibers after 37 C treatment (7th day) are 193.41%, 113.30%, and 197.15%, respectively. With the addition of 5 wt.% CLN, the thermal stability slightly increased compared to the pure TPU and 10 wt.% CLN/TPU. In addition, cytotoxicity studies reveal that CLN/PU membranes are biocompatible, and finally cell adhesion increases proportionally to the increased CLN contribution. The obtained results indicate that the CLN/PU membranes can be used as a skeletal muscle scaffold.

“…The incorporation of clinoptilolite in the nanocomposite membrane led to higher hydrophilicity owing to the presence of hydroxyl groups and higher water flux (13.9 → 20.2

) after 300 min at 0.1 bar pressure, but resulted in a decrease in mechanical strength. The antifouling performance was improved, with a decrease in irreversible fouling rate (19.3 → 6%) and an increase of FRR (80.7 → 94%) for a 0.5 wt.% PVC/clinoptilolite nanocomposite compared to the pristine polymer [ 273 ]. Casadellà et al prepared MMMs by blending different wt.% of clinoptilolite into PSf and PVP matrix for selective recovery of

Nanomaterials have been extensively used in polymer nanocomposite membranes due to the inclusion of unique features that enhance water and wastewater treatment performance. Compared to the pristine membranes, the incorporation of nanomodifiers not only improves membrane performance (water permeability, salt rejection, contaminant removal, selectivity), but also the intrinsic properties (hydrophilicity, porosity, antifouling properties, antimicrobial properties, mechanical, thermal, and chemical stability) of these membranes. This review focuses on applications of different types of nanomaterials: zero-dimensional (metal/metal oxide nanoparticles), one-dimensional (carbon nanotubes), two-dimensional (graphene and associated structures), and three-dimensional (zeolites and associated frameworks) nanomaterials combined with polymers towards novel polymeric nanocomposites for water and wastewater treatment applications. This review will show that combinations of nanomaterials and polymers impart enhanced features into the pristine membrane; however, the underlying issues associated with the modification processes and environmental impact of these membranes are less obvious. This review also highlights the utility of computational methods toward understanding the structural and functional properties of the membranes. Here, we highlight the fabrication methods, advantages, challenges, environmental impact, and future scope of these advanced polymeric nanocomposite membrane based systems for water and wastewater treatment applications.

“…UF membranes with high water flux in low trans-membrane pressure can achieve the proper rejection of substances such as colloids, proteins and natural organic matters (NOMs). 4 Among different polymers which are used for UF membranes, PVC is an outstanding material due to robust mechanical strength, low cost, good thermal stability, and other excellent properties such as high resistance to acids, bases, and solvents. 5 These great properties make PVC as an interesting choice for UF processes.…”

Degradable membranes were obtained by blending of polyvinyl chloride (PVC) with poly lactic acid (PLA) as biodegradable polymer. The effect of the amount of PLA from 10 to 30 wt% on the PVC membrane properties was investigated. The PVC/PLA(80/20) membrane exhibited higher porosity, water uptake and pure water flux than other fabricated membranes. The PVC/PLA(80/20) membrane in TGA results showed that lower temperature required to decompose the membrane in compare of neat PVC membrane. The effect of the amount of hydroxyapatite (HAp) from 0.0 to 3.0 wt% on the PVC/PLA(80/20) membrane structural and antifouling properties was investigated. With the increase in the amount of the HAp up to 2.5 wt%, membrane porosity, hydrophilicity and pure water flux increased. PVC/PLA(80/20)‐2.5 membrane showed higher surface roughness in compare of neat PVC and PVC/PLA(80/20) blended membrane, resulting in higher antifouling properties. Also in the SEM images, embedding the HAp causes to suppress the macrovoids in the cross section of membrane with a higher number of surface pores, which also had lower pore diameter.The humic acid rejection ratios of all PVC/PLA‐HAp nanocomposite membranes were higher than 87%; and all the nanocomposite membranes exhibited higher reversible fouling ratios (RFRs) than the neat PVC membrane.
