A. INTRODUCTION TO THE THESIS1. The urgency and purpose of the thesis research- The urgency of the thesis: Today, developing polymer nanocompositematerials on the basis of thermoplastic, thermosetting reinforced withnanomaterials to create good impact-resistant products is always studied. Infact, thermoplastics polyamides 6 (PA6), polycarbonates (PC) have beenused as materials to produce many shockproof devices, especially in thefield of national security, such as caps, armor, and body cladding. Theequipment for that soldier requires good impact resistance, durability andlightness. PA6 has some preeminent properties such as durability withhydrocarbon solvents, wear resistance, good fatigue, toughness, highthermal stability, easy processing. The PC has the outstanding feature ofhigh optical transparency, better impact resistance than most otherthermoplastics. Among high-performance nanomaterials for thermoplasticresins, carbon nanotubes (CNT) are a typical agent. CNT has a very highand light mechanical strength. Therefore, if PA6, PC, and CNT areincorporated into a nanocomposite polymer, it is possible to create apotential material to produce impact-resistant equipment for the armedforces.- Purpose: Successful fabrication of polymer nanocomposite on the basis ofPA6, PC thermoplastics, and CNT reinforcement to effectively apply thematerial system to the production of body protection equipment for the armyforces.2. Research content of the thesis (1) Fabrication of PA6/PC blend on the basis of using two compatible substances, SEBS and SEBS-g-MA. (2) CNT denaturation then fabricated polymer nanocomposite based on CNT modified with PA6/PC/SEBS/SEBS-g-MA. (3) Optimize machining parameters and determine suitable mixing sequences for polymer nanocomposite manufacturing. 1 (4) Testing production of some impact-resistant products (hand covers, helmets) from fabricated polymer nanocomposite materials.3. Scientific and practical significance, new contributions of the thesis- Evaluation of dispersion level, interoperability between components andmechanical properties of polymer blends PA6/PC/SEBS/SEBS-g-MA andpolymer nanocomposites PA6/PC/SEBS/SEBS-g-MA/CNT.- Construct the mixing process and the appropriate technological parametersfor polymer nanocomposite manufacturing.- Experimental producting some anti-shock products used in the field ofnational security to meet the specific product standards of police andmilitary.4. The layout of the thesis The thesis has 138 pages including 6 sections: Opening 2 pages;Chapter 1 - Overview 38 pages; Chapter 2 - Experiment and researchmethods 14 pages; Chapter 3-Results and discussion 61 pages; List of worksof the author 1 page; References 11 pages; Appendix 10 pages.. B. THESIS CONTENT CHAPTER 1: OVERVIEW The author has gathered 103 references on the content and researchobjects of the thesis including: Characteristics and applications of PA6, PCand some other thermoplastic. Overview of the situation of research,manufacture and application of polymer blends of thermoplastic resins withcompatible substances, as well as polymer nanocomposites withthermoplastic matrix, especially PA6, PC with reinforcement CNT. Sincethen, the following conclusions are drawn:- PA6, PC is commonly used to make blend polymer and polymernanocomposite such as PA6/PP, PA6/PE, PA6/PC, PA6/CNT, PC/CNT.Types of composites and blends have mostly improved im ...
