“…The thickness of the selective layer was decreased, and the desalination was improved. In addition, Shao et al reported the preparation of a TFC layer by PIP and TMC in an IP process to establish a nodule structure with a cross-sectional thickness of 80-120 nm [98]. The PES substrate was coated with a mixture of CDs, CMPI, and NaOH before the IP process.…”

Carbon dots (CDs) have generated much interest because of their significant fluorescence (FL) properties, extraordinary photophysical attributes, and long-term colloidal stability. CDs have been regarded as a prospective carbon nanomaterial for various sensing applications because of their low toxicity, strong and broad optical absorption, high chemical stability, rapid transfer properties, and easy modification. To improve their functionality, CD/polymer composites have been developed by integrating polymers into CDs. CD/polymer composites have diversified because of their easy preparation and applications in sensing, optoelectronics, semiconductors, molecular delivery, and various commercial fields. Many review articles are available regarding the preparation and applications of CDs. Some review articles describing the production and multiple applications of the composites are available. However, no such article has focused on the types of precursors, optical properties, coating characteristics, and specific sensing applications of CD/polymer composites. This review aimed to highlight and summarize the current progress of CD/polymer composites in the last five years (2017–2021). First, we overview the precursors used for deriving CDs and CD/polymer composites, synthesis methods for preparing CDs and CD/polymer composites, and the optical properties (absorbance, FL, emission color, and quantum yield) and coating characteristics of the composites. Most carbon and polymer precursors were dominated by synthetic precursors, with citric acid and polyvinyl alcohol widely utilized as carbon and polymer precursors, respectively. Hydrothermal treatment for CDs and interfacial polymerization for CDs/polymers were frequently performed. The optical properties of CDs and CD/polymer composites were almost identical, denoting that the optical characters of CDs were well-maintained in the composites. Then, the chemical, biological, and physical sensing applications of CD/polymer composites are categorized and discussed. The CD/polymer composites showed good performance as chemical, biological, and physical sensors for numerous targets based on FL quenching efficiency. Finally, remaining challenges and future perspectives for CD/polymer composites are provided.

“…The resultant membranes exhibited high amino acid rejection and water permeation. Shao et al [82] employed CQDs as the interlayer with the aid of dopamine (PDA) to construct a CQD-intercalated (PDA-CQDs-TFC) membrane. The uniformly distributed interlayer decreased concentration polarization and membrane fouling.…”

Membrane technology provides a reliable and powerful solution to combat the global water crisis by producing fresh water through sustainable desalination. However, the decline in system performance due to membrane biofouling is a limitation and significant efforts have been made to explore fouling control mechanisms and develop simple methods to inhibit or eliminate membrane fouling. Nanotechnology has increased the number of options for the development of antibiofouling membranes by incorporating nanoparticles within the polyamide layer to produce a thin‐film nanocomposite (TFN) structure. This review presents recent advances in the preparation of antifouling TFN membranes and incorporation of different nanoparticles into the design. The review also discusses the strategies and mechanisms for reducing membrane fouling and proposes a future outlook for the field.

Sustainable, sufficient and pure water is vital on earth at present. Of all processes used to purify water, nanotechnology plays an important role. Nanomaterials are available in all stages like membranes in filtration, adsorbents of pollutants, photocatalysts for degradation and for detection of pollutants in water purification. Carbon quantum dots (CQDs), an accidentally invented nanomaterial, like in many applications have supported in water purification in all stages. Hence, it is intended for a mini-review for the water purification techniques with carbon quantum dots (CQDs). The chapter consists of three parts. Many nanotechnological methods are employed in water purification. Among them, nanomembranes play a dominant role in detection, nanofiltration and degradation in water purification. Next, nanomaterials as adsorbents, sensors and photocatalytic activity for water remediation are being investigated largely. Hence, they are discussed in the first part. In the second part, the features of CQDs are considered for its versatile applications. The easy and low-cost preparation of CDQs from easily available materials are investigated from the research published articles. In the third part, an attempt is made to collectively analyze the CQDs contributions as membranes in water purification, to detect the presence of organic, inorganic and dye contamination from water is reviewed. Further, the removal of the harmful and or toxic elements from polluted and impure water is discussed from various research groups.
