I roto i ngā tau 20 kua pahure ake nei, kua whānuitia te whakamahinga o ngā waituhi whakamaroke UV i roto i te ao o te waituhi peita. E ai ki ētahi rangahau mākete,[1,2] e matapaetia ana ka piki ake te tere tipu o ngā waituhi whakamaroke irahiko mā te 10 ōrau.
Nā te whakapai tonu o te hangarau tā anō hoki tēnei tipu. Nā ngā whanaketanga hou o ngā mīhini tā (ngā mīhini whāngai pepa me ngā mīhini tukutuku e pā ana ki te whakaputa tere me ngā waeine waituhi/whakamaroke) me ngā taputapu maroke (te uhi hauota me ngā rama matao) kua piki ake te maha o ngā tono i roto i te umanga toi whakairoiro, tae atu ki ngā pouaka mō ngā mea whakapaipai, te kai, te tupeka, ngā waipiro, ngā puka pakihi, te mēra tika, ngā tīkiti rota me ngā kāri nama.
Ko te hanganga o ngā waituhi tā UV-whakaora ka whakawhirinaki ki ngā taurangi maha. I roto i tēnei tuhinga, kua ngana mātou ki te whakamārama i te tūranga o te whanonga ā-tinana o te monomer i roto i tētahi tunu waituhi. Kua whakaahuahia katoatia e mātou ngā monomer i runga i te taumahatanga ā-mata kia taea ai te matapae i tō rātou whanonga ki te wai i roto i tētahi tukanga tuhi.
Hei tāpiritanga, kua hangaia ngā waituhi ki ēnei monomer, ā, kua whakaritea ngā āhuatanga o te waituhi whakamutunga.
Ko ngā monomer katoa i whakamahia i roto i te rangahau he hua nō Cray Valley. Kua hangaia ngā monomer GPTA hei whakarerekē i tō rātou hononga ki te wai.
