A membrane permeable to water vapor was prepared and used for dehumidification of air. At a given feed flow rate, the permeation ratios were almost independent to relative humidities of feed stream; The permeation ratios were about 45%, 60%, and 25% at feed flow rate of 50, 70, and 90cc/min, respectively. Permeation ratio might also be enhanced with increasing feed flow rate. However, the permeation ratio (about 25%) at a feed flow rate of 90cc/min was much less than at 50cc/min (about 45%) and 70cc/min (about 60%). This phenomenon might be explained that a water film does form at surface of membrane because the amount of water vapor contained in feed stream of 90cc/min was much more than the permeate through the membrane.

Background and objective: Graphene-based nanomaterials have received increasing attention due to their unique physical-chemical properties including two-dimensional planar structure, large surface area, chemical and mechanical stability, superconductivity and good biocompatibility. On the other hand, graphene-based nanomaterials have been explored as theranostics agents, the combination of therapeutics and diagnostics. In recent years, grafting hydrophilic polymer moieties have been introduced as an efficient approach to improve the properties of graphene-based nanomaterials and obtain new nanoassemblies for cancer therapy. Methods and results: This review would illustrate biodistribution, cellular uptake and toxicity of polymergraphene nanoassemblies and summarize part of successes achieved in cancer treatment using such nanoassemblies. Conclusion: The observations showed successful targeting functionality of the polymer-GO conjugations and demonstrated a reduction of the side effects of anti-cancer drugs for normal tissues.
