Question 1

what are natural polymers and biomaterials?

Answer 1

abundant and renewable boipolymers-multi-functional materials
-starch
-cellulose
-chitosan

Question 2

what is starch?

Answer 2

-derived from edible plants and grains, linear vs. branched vs. cyclic poly-glucose

Question 3

what is cellulose?

Answer 3

-derived from biomass, a linear poly-glucose

Question 4

what is chitosan?

Answer 4

derived from chitin, a linear glucosamine based biopolymer that resembles the structure of cellulose (different occurs at C-2)

Question 5

what is the design of tunable biopolymer materials?

Answer 5

Question 6

what are chitin and chitosan biopolymers?

Answer 6

Question 7

what are modified chitosan biopolymers?

Answer 7

Question 8

what are adsorption processes? What are the challenges for ion removal?

Answer 8

-sustainably removal of ions is a technical challenge due to favourable change in G hydration and physical properties of ions (shape, size and charge)
-separation depends on surface area and surface interactions
-adsorption methods are low-cost, efficient, but are limited by the nature of the adsorbent phase
