- 3. INTRODUCTION TO POLYMERS •A POLYMER IS A LARGE MOLECULE COMPOSED OF MANY REPEATED SUBUNITS. THERE ARE SYNTHETIC AND NATURAL POLYMERS , WHICH PLAY AN ESSENTIAL ROLE IN OUR EVERYDAY LIFE . AN EXAMPLE OF SYNTHETIC POLYMERS IS POLYSTYRENE AND OF NATURAL OR BIOPOLYMERS IS DNA AND PROTEINS.
- 4. 1ST ACTIVITY CHANGING OF POLYMERPALLETS • IN THIS EXPERIMENT WE USED 0.50G OF POLYMER AND POURED ON IT 10ML OF WATER, NEXT WE SAW THE DIFFERENCES IN THE WEIGHT OF THE POLYMERS BETWEEN THE START AND THE END (FINAL RESULT). • AFTER THAT WE EXPOSED OUR TWO BEAKERS OF POLYMERS TO TWO TYPES OF WATER ( NORMAL WATER AND WATER WITH SALT ).WE REALIZED THAT THE POLYMERS SIZES AND WEIGHTS CHANGED AGAIN DEPENDING ON CONCENTRATION. THERE ARE DIFFERENT TYPES OF POLYMERS, SOME EXAMPLES ARE : • NATURAL POLYMERS WHICH ARE POLYMERS FOUND IN NATURE LIKE: PROTEINS AND NUCLEIC ACIDS. • SEMI-SYNTHETIC POLYMERS, THESE ARE MOSTLY DERIVED FROM NATURALLY OCCURRING POLYMER BY CARRYING OUT CHEMICAL MODIFICATION. • SYNTHETIC POLYMERS: THE POLYMERS MADE IN THE LABORTORY AND ARE CALLED MAN- MADE POLYMERS. 2ND ACTIVITY: HUNTING FOR POLYMER PRODUCTS 3RD ACTIVITY COMPARING VISCOSITY OF POLYMERS IN THIS EXPERIMENT WE USED THREE DIFFERENT DENSITIES OF POLYMER SOLUTIONS PVA(1G, 5G, 10G, 100MW, 170MW, 260MW). THEN BY USING A DROPPER PIPIT WE MEASURED 4.5CM OF EACH POLYMER SOLUTION AND GENTLY SPREADING IT ONTO GLASS FILMS . WE LEFT THEM FOR A DAY TO DRY.
- 5. ACTIVITY 4 TESTING FOR TENSILE STRENGTH AND ELASTICITY •AFTER LEAVING THE POLYMER FILMS TO DRY FOR A DAY WE SCRATCHED THEM USING METAL BLADES THEN PLACED ONE PIECE ON A BURETTE (STAND) AND HANGED A MASS ON IT, THE DIFFERENT WEIGHTS OF POLYMERS GIVE US DIFFERENT RESULTS AND SHOWED DIFFERENT TENSIBLITIES.

- 6. DESIGN PROJECT( DESIGNING HUMIDITYSENSOR ) • WE MADE NON-ELECTRICAL HUMIDITY SENSORS USING POLYMERS, POLY- VINYL ACETATE/ POLYVINYL ALCOHOL, SOLVENT, 2 BUTANONE AND INDICATOR, COBALT CHLORIDE. WE SPREAD THE SOLUTION ON A GLASS SLIDE TO MAKE A POLYMER SENSOR FILM WHICH WHEN EXPOSED TO WATER VAPORS CHANGED COLOR FROM A DARK BLUE SHADE INTO A PINKISH PURPLE COLOR, INDICATING HUMIDITY.
- 7. ANTI-MICROBE ATM CARDS •AFTER DOING A LOT OF RESEARCH, WE, THE MEMBERS OF THE GROUP PROFESSOR X CAME UP WITH THIS PRODUCT IDEA. ANTI-MICROBE CARDS IS A NEW INVENTION THAT WILL HAVE MANY BENEFITS ON THE SOCIETY. OUR PRODUCT USES PHENOLIC BIOCIDE (A POLYMER) TO HELP IN DECREASING THE NUMBER OF GERMS, BACTERIA AND VIRUSES BEING SPREAD THROUGH THE CARDS, WE CHOSE THIS POLYMER NOT ONLY BECAUSE IT’S AN ANTI-MICROBE POLYMER, ALSO BECAUSE IT’S COSTS AREN’T VERY HIGH.
- 8. HYPOTHESIS • WE EXPECTTHE CARDS TO REPEL THE BINDING OF GERMS TO THE SURFACE OF THE POLYMER CARDS. ALSO THEY COULD BE KILLED DURING CONTACT WITH THE BIOCIDE POLYMER EMBEDDED IN THE ATM CARD.
- 9. ANTI-MICROBE ATM CARDS METHODSAND MATERIALS TO MAKE THE USUAL ATM CARDS PVC (A POLYMER) IS MIXED WITH OTHER MATERIALS LIKE DYES AND PLASTICIZERS, IN OUR PRODUCT WE WILL ADD AN ADDITIVE CALLED PHENOLIC BIOCIDE WHILE MANUFACTURING THE CARDS TO MAKE THE ANTIMICROBIC ATM CARDS.
- 10. ANTI-MICROBE ATM CARDS RESULTS THERESULTS EXPECTED TO BE OBTAINED IS THAT LESS GERMS, VIRUSES AND BACTERIA WILL BE TRAVELLING FROM HAND TO HAND OR PURSE TO HAND DUE TO THAT LESS DISEASES WILL BE SPREAD AND THIS WILL PROVIDE A SAFER ENVIRONMENT. ALSO, THE EFFICIENCY OF THE MATERIAL IS PROVED BY MANY COMPANIES IN PROVIDING GERM-FREE PLASTICS AS FOOD CONTAINERS.
- 11. ANTI-MICROBE ATM CARDS RECOMMENDATIONS WERECOMMEND OUR MATERIAL TO BE USED FOR MAKING PENS AND ALSO ANTI-BACTERIAL PLASTIC CARD HOLDERS . ALSO, WE RECOMMEND TO INCORPORATE ANTI-MICROBIAL POLYMERS TO THE MONEY HOLDING LAYERS OF THE POUCH OR THE WALLETS THAT IS A BREEDING ENVIRONMENT FOR THE GERMS. WE CAN ALSO EMPLOY A CARD CLEANING DISPENSER WITH ANTI-MICROBIAL POLYMER SOLUTION INTEGRATED WITH THE ATM MACHINES.
- 12. CONCLUSIONS AFTER ALL OFTHIS LONG RESEARCH AND WORKSHOP, WE ARE NOW HAVING MORE KNOWLEDGE ABOUT POLYMERS. PARTICIPATING IN AL-BAIRAQ HELPED US IN IMPROVING OUR RESEARCH SKILLS AND IN ORGANIZING OUR TIME, BETWEEN FINISHING THE RESEARCH AND MAKING THE POSTER AND PRESENTATION ALSO WITH ALL OUR SCHOOL WORK.IT MADE US MORE INDEPENDENT AND IT TAUGHT US HOW TO WORK IN A GROUP AND BE RESPONSIBLE.
- 13. ACKNOWLEDGMENT MANY THANKS TOMY TEACHERS, SCHOOL AND AL-BAIRAQ TEAM FROM CENTER FOR ADVANCED MATERIALS (CAM), QATAR UNIVERSITY FOR SUPPORTING US DURING OUR JOURNEY WITH A AL-BAIRAQ. ALSO, I WOULD LIKE TO THANK THE SPONSORS UNESCO, QATAR NATIONAL COMMISSION.
