Why Specify Film/Foil Capacitors?
Film/Foil capacitors consist of two aluminum foils acting as the electrodes. These foil electrodes are separated by a polymer film dielectric. These materials are non
Capacitors
A foil cap has to have a dielectric layer, usually film, usually polypropylene. Most film & foil types are therefore polypropylene. The difference between a ''regular'' polypropylene and a ''film & foil'' polypropylene is the metal sheet in the F&F type. A regular cap has a metalized film instead (like those mirrored balloons you see).

Aluminum Foil and Electrolytic Capacitor Technology
Recent research has focused on various methods to enhance the properties of aluminum foil, including additive manufacturing, anodizing processes, and the effects of surface treatments.
Storage: Antistatic bags
Antistatic bags, or, at least aluminum foil wrapped around the leads is necessary for some active components, especially MOS logic ICs, RF parts and other sensitive components, like ADCs. Passive components like resistors or capacitors can be stored anywhere.
Aluminum Foil Capacitor Lab
a.) Use two equal sized sheets of aluminum foil and a large textbook to make your own capacitor. Use the capacitance meter to find the capacitance of your home-made capacitor. Make different capacitors by inserting between the sheets at least 5 different separations in your textbook (i.e. 30 pages, 60, 90, 120, 150 works well.)

Aluminum Electrolytic Capacitor Primer
Aluminum electrolytic capacitors utilize an "anode" (+) electrode made of high-purity etched aluminum foil. The anode etching process increases the surface area of the foil by creating microscopic tubes. This gives AE caps their high capacitance.
Homemade aluminium foil capacitor
If you have the multimeter connected, then the capacitor is discharging through the multimeter input resistance (typically 10 megohms). If you want to monitor the voltage without significantly discharging the capacitor, you will need a very high input impedance buffer circuit, such as the plus input of a MOSFET input op amp connected as a gain-of-one buffer circuit, or

6 FAQs about [Do capacitors need aluminum foil ]
How is an aluminum electrolytic capacitor constructed?
As previously mentioned, an aluminum electrolytic capacitor is constructed by using two strips of aluminum foil (anode and cathode) with paper interleaved. This foil and paper are then wound into an element and impregnated with electrolyte. The construction of an aluminum electrolytic capacitor is illustrated in Fig. 1-1.
How do aluminum foil capacitors work?
A 0.05~0.11 mm thick anode foil and a 0.02~0.05 mm thick cathode foil are continuously etched electrochemically in a chloride solution with an AC or DC current. This enlarges the effective surface area of the aluminum foils to attain smaller capacitor sizes. The process develops aluminum oxide (Al203) to form a capacitor dielectric.
Does cathode foil have a capacitance?
The cathode foil has a capacitance (Cc) that uses the oxide layer, which formed by the forming voltage or formed naturally during storage (generally 1V or less), as a dielectric. According to the construction of aluminum electrolytic capacitors, Ca and Cc are connected in a series.
Why do aluminum electrolytic capacitors have a higher capacitance?
Therefore, aluminum electrolytic capacitors have a higher capacitance for a specified apparent area than other types of capacitors. High purity aluminum foil for the anode is etched by electrochemical process in a chloride solution with DC, AC, or an alteration of DC and AC, or a concurring AC and DC current.
Are aluminum electrolytic capacitors safe?
Furthermore, the PL Law (Product Liability) has been enforced, therefore, safety is regarded as important more than before. For such reasons, aluminum electrolytic capacitors that are used in power supplies are required to have the following features: miniature, light in weight, thin, extended life and high reliability, chip type, and safer.
Can aluminum electrolytic capacitors be applied for a short time?
Aluminum electrolytic capacitors can be applied for a short time with an overvoltage, also called a surge voltage.
