Minimum success has been achieved in this field, although it has been heavily investigated for enhanced mechanical and diffusion properties. Due to their high isotropic properties, HNTs have a wide range of applications such as tensile and compressive strength enhancers and thermal, diffusive, and capacitance modifiers, etc. Particle alignment has been extensively explored in polymeric systems. However, most studies focus on the planar alignment, which do not take advantage of these anisotropy since the orientation in thickness direction (Z-direction) is not achieved. Hence, directed assembly techniques are introduced as a good assisted method to meet the requirement. Field assisted assembly has already been broadly introduced, but there are still questions involving specific systems. One of them is how to form an ordered structure in “Z”- direction by utilizing these assembly techniques, in order to meet the `’Z’’-aligned structure requirement of most membranes and films for electronic devices. Therefore, the objective of this investigation is to utilize field assisted assembly to achieve `’Z’’- alignment of particle chain-like formations in polymeric matrices under electric field. Traditional characterization techniques have been broadly used to investigate particle orientation in polymer nanocomposites such as scanning electron microscope (SEM), wide angle X-ray diffraction (WXRD). However, these techniques are unable to capture the real time molecular dynamics during alignment. As a result, a real time birefringence measurement system developed by our group was introduced to analyze the dynamics of HNT orientation in a Norland 65 (NOA65) polymer matrix during electric field assisted alignment. 2016-06-13 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1462917071 http://rave.ohiolink.edu/etdc/view?acc_num=akron1462917071 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
