The development of smart phones is changing day by day, various brands of cell phones continue to introduce new, increasingly powerful features, face value is also increasingly high, to say which is the strongest cell phone face value? From the front, it's a bit like the Miss Korea pageant, it's really hard to distinguish between them.
Let's take a look at the back, look at the back cover of the phone, talk about the back cover of the phone material yesterday, today and tomorrow.
Plastic
In the early days, the most common cell phone back cover, is made of plastic, this material is inexpensive, malleable, low technical difficulties, favored by various cell phone manufacturers. In order to tear off those "low-end", "cheap" label on the plastic, good at "messing with the machine" manufacturers to make a variety of attempts. Among them, polycarbonate ((Polycarbonate, PC)), with excellent transparency, high impact strength at room temperature, high temperature resistance and high rigidity characteristics, the most widely used. Polycarbonate can enhance the texture at the same time, but also through the surface treatment to achieve a different sense of touch, Samsung and Nokia are its loyal fans.
iPhone 5c hard PC back cover of glossy highlights, appearing high-grade exquisite, surface treatment application UV paint, enhance the texture at the same time, more scratch-resistant. Samsung Galaxy S5, after the surface treatment of polycarbonate, the touch feels like a soft sheepskin.LG G3's plastic back shell shows a brushed metal effect.
The plastic material is here first, let's talk about the glass.
Glass
Speaking of glass back cover, once the most representative of the iPhone 4/4S, in addition, from the early Google's Nexus 4, Sony Z2, to the latest Samsung Galaxy S8/S8 Plus, Nut Pro, Xiaomi 6 and so on have launched glass back cover.

Metal material can be said to be the most popular fried chicken. Almost all mainstream manufacturers have launched metal cell phones. Metal cell phones have texture, feel, face value, scratch resistance, drop prevention, is simply someone else's child, is the embodiment of perfection. However, even under the huge halo, the shortcomings will eventually surface: all-metal cell phones will screen! The phone will be screened! Handset! The cell phone! The letter! signal! If this problem in the 4G era is barely justifiable, but in the 5G era, this shortcoming will be infinitely enlarged, all of you and use and cherish.
5G era, the requirements of the cell phone back cover materials to minimize the impact of the cell phone signal, then it is the metal era facing the end, who will become the next protagonist? Ceramics, glass and a variety of composite materials can be an alternative program. Ceramic and glass appearance of high-grade, but the high cost, not drop resistance will become a constraint to hinder its development. Several manufacturers are now stepping up their research and development of ceramic and glass for drop resistance.
So, what other composite materials can be an alternative?
