Polymers,Superabsorbent polymer keeps the armpit dry,IDM9

Done by Group : Professors School Name : Alshahaniya Independent Secondry School for Boys. Polymers Module : Through this module, students examine the different properties of the variety of polymers. Then they design and test a humidity sensor made of a polymer film. Finally, they are asked to design their own products. the product Idea is : using Superabsorbent polymer to keep the armpit dry & prevent bad smell of sweating to appear.

  • 1. • Introduction • Activity 1: Changing polymer pellets • Activity 2: Hunting for polymer products • Activity 3: Comparing the viscosity of liquids • Activity 4: Testing the strength of different polymer films • Design Project (Designing a Humidity Sensor) • Product Idea (Superabsorbent polymer Keeps the armpit dry.)
  • 2. Polymer is Huge molecules that consist of a multiple small molecules called (monomers).
  • 3.  Objective : Understand how Polymer pellets work.  Procedure : 1) Prepare two samples 0.5 g of polymer pellets 2) Add 10 ml of water to each sample , then observe the results 3) Measure the mass to each sample 4) Add 10 ml of plain water to sample A , & 10 ml of saturated salt water to sample B , then observe the results 5) Filter leftover liquid to make samples easier to handle, by using paper towel , then measure the mass of samples
  • 4.  Results : Polymer absorbs water , so the mass of pellets increased in both samples after addition of plain water for the first time. Sample A absorbed more water after addition of plain water for the second time Sample B released the water after addition of the salt water  Conclusion : water moves through polymer depends on Osmosis of water ( moving of water molecules from low salt concentration to high salt concentration ) .
  • 5. Activity 2 Hunting for polymer products • Objective : Make a data table that contain : 1) Name of products made of polymers 2) Uses of products 3) Type of polymer ( natural / synthetic ) 4) Name of polymer 5) Physical properties of the polymer • Procedure : 1) List in data table the polymer products in the room , then describe its uses 2) Determine type of polymer ( natural / synthetic ) , then identify the polymers name 3) Describe the physical properties of the polymer 4) Compare the number of polymer products , then identify products as being made of polymers
  • 6. Activity 2 Hunting for polymer products • Results : Synthetic: natural: 1) Plastic 1) Silk 2)Fabrics 2) wool 3)Insulation 3)Papers
  • 7.  Conclusion : Polymers ( natural or synthetic ) are used & found in most of products in our life . Activity 2 Hunting for polymer products
  • 8.  Objective : Knowing about the viscosity of liquids & the amount of time that bubble takes to move through each liquid  Procedure : 1) Examine the liquid of each vial , then record the observation 2) Turn over the vials , then record the time that it takes air bubble to reach to the opposite end by using stopwatch
  • 9.  Results : Bubble moves faster in Methanol , then Ethylene glycol , then Glycerol have the slowest movement  Conclusion : Polymers with higher molecular weight have highest Viscosity , & Polymers with lower molecular weight have less Viscosity
  • 10.  Objective :  knowing the strength of different polymers films  Procedure :  label two microslides with the molecular weight of one of the poly(vinyl acetete) Solutions .  Use the pipette to draw the appropriate poly(vinyl acetate) solution.  Dispense the solution from the pipette as evenly as possible onto the unlabeled side of one of the slides .  Use a coin to drop a watch glass over the two slides .
  • 11.  Results : PVAc 260 have the highest strength. PVAc 100 have the lowest strength.  Conclusion : when the molecular weight increase the strength of the polymer films will increase.
  • 12.  Objective: Design a Humidity Sensor  Procedure/prototypes : 1) Design a thin polymer film made of three different polymers 2) The sensor must be durable 3) The sensor contain Cobalt (II) Cholride as indicator ( blue – dry , pink – wet ) 4) The sensor gives visual response within 10 min 5) The sensor have reversible response
  • 13.  Results : Sensor number 3 that made of polyvinyl alcohol gives the best model of humidity sensor  Conclusion : the best polymer that used in humidity sensor that have less molecular weight
  • 14.  Introduction and Rationale:  Some polymers have high ability to absorb water in its spaces, so we can use Superabsorbent polymer ( SAPs ) [ Slush Powder ] to absorb sweat in armpit to keep it dry, then we can prevent bad smell of sweating to spread.  Aim of the work (objectives)  using Superabsorbent polymer to Keeps the armpit dry & prevent bad smell of sweating to appear.
  • 15.  Hypothesis :  Superabsorbent polymer can absorb sweat & Keeps the armpit dry.
  • 16.  Product Story : Through working with Al-Bairaq team we learned a lot about polymers, specially that some polymers have ability to absorb water, & be gel-like shape. So we think about using sticks that prevent bad smell of sweating to appear in armpit, specially people who has Sweating problem.
  • 17.  Materials & Methods : 1) Superabsorbent polymer (Slush Powder) 2) Cotton 3) Cotton Sacs Put Superabsorbent polymer in thin sacs that contain cotton , that be permeable to sweat to be absorbed.
  • 18.  Results:  Professors stick prevent bad smell of sweating to appear. This is the first stick that use, so its efficient for peoples have high sweating secretion.
  • 19.  Recommendations : We recommend pharmaceutical factories to use & develop our product. Cost-benefit of the project are high, because peoples need to find an efficient solution for bad sweating smell.
  • 20.  Conclusion : Using of Professors stick prevent bad smell of sweating to appear We get high experience by participate with Al-Bairaq competitions.
