AB  - This study was inspired by the unique multi-scale and multi-level 
      'brick-and-mortar' (B&M) structure of nacre layers. We prepared the B&M, 
      environmentally-friendly graphene oxide-carrageenan (GO-Car) nanocomposite films 
      using the following steps. A natural polyhydroxy polymer, carrageenan, was 
      absorbed on the surface of monolayer GO nanosheets through hydrogen-bond 
      interactions. Following this, a GO-Car hybridized film was produced through a 
      natural drying process. We conducted structural characterization in addition to 
      analyzing mechanical properties and cytotoxicity of the films. Scanning electron 
      microscope (SEM) and X-ray diffraction (XRD) analyses showed that the 
      nanocomposite films had a similar morphology and structure to nacre. Furthermore, 
      the results from Fourier transform infrared spectroscopy (FT-IR), Raman 
      spectroscopy, X-ray photoelectron spectroscopy (XPS) and Thermogravimetric 
      (TG/DTG) were used to explain the GO-Car interaction. Analysis from static 
      mechanical testers showed that GO-Car had enhanced Young's modulus, maximum 
      tensile strength and breaking elongation compared to pure GO. The GO-Car 
      nanocomposite films, containing 5% wt. of Car, was able to reach a tensile 
      strength of 117 MPa. The biocompatibility was demonstrated using a RAW264.7 cell 
      test, with no significant alteration found in cellular morphology and 
      cytotoxicity. The preparation process for GO-Car films is simple and requires 
      little time, with GO-Car films also having favorable biocompatibility and 
      mechanical properties. These advantages make GO-Car nanocomposite films promising 
      materials in replacing traditional petroleum-based plastics and tissue 
      engineering-oriented support materials.
