14 Polymer History
15 1570
16 Charles Goodyear 1839
17 1907 Dr. Leo Baekeland Bakelite- the first synthetic plastic.
18 Bakelite Radios, telephones and electrical insulators were made of Bakelite in the past due to its insulating and heat-resistant properties.
19 1917 M.Polanyi Used X-ray crystallography to discover the chemical structure of cellulose-a long chain molecule.
20 1920 Hermann Staudinger Staudinger s classic paper Uber Polymerization presented the world the development of the modern polymer theory.
21 1927 Large scale production of polyvinyl-chloride (PVC) resins begins.
22 PVC
23 1930 Polystryrene is invented.
24 Styrofoam
25 1938 Wallace Carothers of Dupont company produces nylon.
26 Nylon
27 1941 Polyethylene is produced.
28 Polyethylene
29 1970 James Economy develops Ekonol.
30 Ekonal A moldable polymer that has no observable melting point! Leads to the development of liquid crystal polymers 1 year later.
31 1971 Aramid
32 Aramid Kevlar
33 1976 Polymer/plastic industry passes steel as the nation s most widely used material.
34 Plastics! Now we use more plastic than steel, aluminum and copper combined!
35 Carbon-Fiber
36
37 Plastics Usage in Cars Automotive Usage (lbs.) Year
38 Strongest Material?
39 Carbon Nanotube Application Anti-Ballistic Materials
40 Bullet-proof jackets stop bullets from penetrating by spreading the bullet's force. Targets can still be left suffering blunt force trauma, perhaps severe bruising or, worse, damage to critical organs.
41 Scientists use the elasticity of carbon nanotubes to not only stop bullets from penetrating but to actually rebound their force.
42 2008 A polymer that transforms into a fireproof ceramic.
43 HIPS Coating Hybrid Inorganic Polymer System Withstand temperatures over 1000ºC!
44 Lithium-ion Battery Fires
45 2011 Touchscreens
46
47 Touchscreens that contain carbon nanotubes can be made of low-priced renewable raw materials.
48 2011 Flexible plastic electronics!
49 The bilayer dielectric is made of a fluorinated polymer known as CYTOP.
50 The bilayer dielectric is also made with a High-k metal oxide layer.
51 Alone, each substance has its drawbacks but together, each substance retains its benefits and their drawbacks are cancelled out!
52 Medical Applications
53
54 The NanoTech Institute recently announced the development of artificial muscle tissue that is 100 times stronger than natural human muscles. Applications: artificial limbs and perhaps even artificial heart tissue.
55 Cancer Cells One of cancer's cleverest tricks is its ability to hide from the immune system.
56 Polymer Nano-Trainer Researchers have developed a polymer implant attracts and trains immune-system cells to go after cancer.
57 The macroporous poly-lactide-co-glycolide (PLG) polymeric matrix used in the study has a history of safe use in humans.
58 The implant could also be used to treat diseases such as arthritis and diabetes, and, potentially, to train other kinds of cells, including stem cells used to repair damage to the body.
59 Artificial Bone Marrow Artificial bone marrow that can continuously make red and white blood cells has been created in a University of Michigan lab.
60 First, scientists create biodegradable scaffolds.
61 The scaffolds are then seeded with artificial bone marrow cells and osteoblasts, another type of bone marrow cell.
62 It is designed to function in a test tube.
63 Antifreeze Protein A new protein discovered in tiny snow fleas by Queen s University researchers may lengthen the shelf life of human organs for transplantation.
64 Construction Applications
65 Construction Conventional means of internal reinforcement for concrete member in buildings involve steel bars (Rebar).
66 Fiber Reinforced Polymer (FPR)
67 Liquid Wood
68 Liquid Wood Most plastics are based on petroleum.
69 Produce plastic granulate that can be melted and injection-molded. Liquid Wood Wood Wax Hemp
70 Metal Rubber Polymer chemists have created a flexible, indestructible material called metal rubber.
71 Metal Rubber It can be heated, frozen, washed or doused with jet fuel, and still retain its electricity-conducting properties.
72 To make metal rubber, chemists and engineers use a process called self-assembly. The material is repeatedly dipped into positively charged and negatively charged solutions. The positive and negative charges bond, forming layers that conduct electricity.
73 Uses of metal rubber include electrically charged aircraft wings, artificial muscles and wearable computers.
74 Industrially Important Polymers These polymers are produced in high volume at very low cost.
75 Industrially Important Polymers About 85% of the world plastics consumption is from just four polymers.
76 Industrially Important Polymers POLYMER MER APPLICATIONS Polyethylene (PE) electrical wire insulation, flexible tubing, squeeze bottles Polypropylene (PP) carpet fibers, ropes, pipes liquid containers (cups, buckets, tanks)
77 Industrially Important Polymers POLYMER MER APPLICATIONS Polystyrene (PS) packaging foams, egg cartons, lighting panels, electrical appliance components Polyvinyl Chloride (PVC) bottles, hoses, pipes, valves, electrical wire insulation, toys, raincoats
78 Polymer Formation Polymerization
79 Free Radical Polymerization Two bonds between the two carbons ruptures. Two free radicals meet, they can form a dimer with a new covalent bond linking the two.

110 Elastomers Are usually thermosets but may be thermoplastics.
111 Response to Heat Thermoplastic Softens or melts with heat The polymer chains start to relax as they gain energy. They lose some of their crystallinity.
112 Thermoplastics Styrofoam PVC Nylon Thermoplastics can be reformed and recycled.

117 Response to Heat Thermoset Sets with chemical reaction
118 Thermosets Thermosets are not recyclable and are more brittle.
119 Polymer Production Polymers are formed by many low temperature processes.
120 Extrusion The polymer is heated to the liquid state and forced through a die under pressure.
121 Extrusion This results in an endless product of constant cross section.
122 Examples include: tubing, pipes, window frames, insulated wire. Extrusion 60% of all polymers are prepared this way.
123 Film Blowing The material coming out of the die is blown into a film.
124 This process is used extensively with polyethylene and polypropylene. An example is plastic wrap.
125 Injection Molding Similar to extrusion, the polymer is heated to the liquid state, but it is prepared in metered amounts.
126 Injection Molding The melt is forced into a mold to create the part. It is not a continuous process.
127 Injection Molding Many toys are made by injection molding.
128 Blow Molding A melted polymer is put into a mold.
129 Blow Molding Compressed air is used to spread the polymer into the mold.
130 Blow Molding This process is used to make many containers such as plastic soda containers and milk jugs.
131 Compression Molding A solid polymer is placed in a mold, the mold is heated and puts pressure on the polymer to form the part.
132 Reaction Injection Molding
