5 CONCLUSÕES
A modificação superficial do tecido de malha de PLA, utilizando a mistura
2 4
O CH
M diminuiu o ângulo contato no lado tratado com oxigênio e aumentou o ângulo
de contato no lado tradado com metano. O tratamento com 2
4
O CH
M , no lado direito da amostra revelou um aumento dos
grupos polares C-O e O=C-O e uma diminuição dos grupos apolares C-C.
O lado direito da amostra tratado com oxigênio apresentou erosão causada pelo tratamento a plasma e o lado avesso tratado com metano observa-se a formação de um filme de metano.
O melhor resultado para o tratamento com 2 4 O CH M foi o de 2 4 60 40 O CH M potência de 100 W e durante 30 minutos.
Tratamentos com Argônio e Nitrogênio mostraram que o tratamento com nitrogênio proporcionou uma maior área de espalhamento do líquido quando comparado com o tratamento com Argônio.
A utilização da mistura 2 4
N CH
M inibiu a ação do nitrogênio reduzindo a área de
espalhamento do líquido.
O aumento da potência aumentou o efeito polimerizante do plasma de metano reduzindo a área de espalhamento do líquido.
A variação do %CH4 interferiu no controle da cinética de espalhamento do
líquido na capilaridade horizontal.
A área de espalhamento do líquido tem valor maior do lado direito da amostra tratado com nitrogênio quando comparado com o lado tratado com metano.
A cinética de espalhamento do líquido é maior utilizando o nitrogênio quando comparado com o metano.
A variação do %CH4 interferiu no controle da cinética de arraste capilar do
líquido na capilaridade vertical.
A altura de arraste vertical tem valor maior no sentido das carreiras do que das colunas.
A resistência à tração e % de alongamento não foram alterados após o tratamento a plasma de nitrogênio e metano.
