2. Experimental design, materials, and methods
2.1. Design, materials, and methods
There are many methods to synthesis various materials with many combinations [1], included synthesis silver and titanium dioxide nanocomposite materials [2]. El-Nour et al. [3] describe there are 2 major synthesis of Ag nanoparticle, which are physical approach and chemical approach. Krutyakov et al. [4] also explained the synthesis Ag nanoparticles that divided into two synthesis methods, which are conventional and unconventional methods. Natsuki et al. [5] explained the synthesis Ag nanoparticle using 4 main methods, which are Physical method, photochemical method, Biological method, and chemical method. A more detailed explanation about synthesis TiO2 are proposed by Chen and Mao [6], where they explained that there are 11 main methods that can be used to synthesis TiO2 nanomaterial such as; Sol-gel method, Michelle and Inverse Michelle method, Sol method, hydrothermal method, Solvothermal method, Direct oxidation method, Chemical vapor deposition method, Physical vapor deposition method, and Electrodeposition method, Microwave method, and Sonochemical method.
Among many methods that can be used to synthesize Ag and TiO2, Physical Vapor Deposition (PVD) method is one of the simplest methods with high purity output. The materials are evaporated in the high temperature and reach its melting point. The material then thermally deposited in the lower temperature and then condensed to form as a solid. High temperature and low pressure are used to increase the synthesis process.
The present paper used a modified method of PVD to reduce the cost by using quart tube. Since the process use quartz tube and it were placed in the furnace with horizontal position, the method is called Horizontal Vapor Phase Growth (HVPG) technique. The sequence of synthesis Ag/TiO2 nanocomposite material can be described in Fig. 4. Detail method with a detailed flowchart of HVPG technique can be found in Muflikhun et al. [7]. Source material consists of 17.5 mg Ag powder from Aldrich Corporation and 17.5 mg TiO2 from Degussa P25 were prepared. As a medium for growth nanocomposite, cheap quartz tube from heater components was used as shown in Fig. 5. The tube then washed and cleaned before sealing with a blowtorch at one-end. Before materials poured into the tube, the powder that contains of Ag and TiO2 were mixed to gain equal distribution in each part.

Fig. 5.

The tube that contains material (powder) then placed in the vacuum machine to remove air and pollutant that may occur. After the condition inside the tube becomes a vacuum with pressure reach 10−6 Torr, the tube then sealed in the both-end. The tubes, then placed vertically in the furnace with half position inside the furnace and half position outside the furnace. Temperature of growth and baking time is set from the furnace with automatic off after the time fulfilled.
After cooling process, the tubes that contain nanocomposite materials then cracked by using a gavel with a slow push to avoid material inside the tube to move. Small sample in each zone then placed in the SEM sample plate to be analyzed.
2.2. Measurement technique
Since it was invented by German researcher and inventor, Manfred von Ardenne in 1938, SEM is used by many scientists all around the world for analyzing and constructing tiny object to nanoscale materials. Over the past decades, development of SEM to attain higher precision, clearer image output, and faster operation process have made the nanotechnology field and analysis nanomaterial more attractive for researchers [8].
The main function of SEM is like a microscope in general, to see small objects to be seen clearer. The main difference with light microscope is the scope of SEM can have magnification to look the object up to nano scale. This ability makes SEM is used by many researchers as the vital equipment to develop new material at nano level [9].
The data shows SEM image was capable to analysis the size and measure the diameter and size of nanocomposite material that consist of Ag/TiO2. Since Ag/TiO2 nanocomposite material was reported by many researchers that can be used in various applications, for instance: anti-bacterial application [10], clean and renewable fuel [11], sensor application [12], and multifunctional applications (UV resistance, UV protection, and increase wear properties) [13].
The material measurement used random object that clearly placed in one frame. Furthermore, the measurement technique used ISO 13322-1 as a standard for measuring object [14]. The parts choice based on the object that fully located in the scope of one frame. The object that out of frame is excluded except the main body of the object can be fully recognized. At least 3 measurements are done in one frame. The object that measured are allocated in the frame with all parts of the object is shown clearly and all objects to be measured is within the frame scope. The object analysis is illustrated in Fig. 6. Grey objects can be measured and calculated, and the white object is expelled from measured and not be calculated.

Treatment of objects that cut by the edge from SEM image.
Specimens measurement technique in different parameter is shown in Fig. 7 and Fig. 8. Different shape of nanocomposite material in the different zone is shown in Fig. 7. It is shown that different shape also has different measurable. Fig. 8 shows the different shape of nanocomposite material in different baking time. The measurement value shows that diameter of the material shows different with the increase of baking time.
