A simple code can be used to depict the schematic diagram of the polymer network. (To solve the pain of manual depiction)
clc,clear,close all N = 200; % The length of chains. P = 200; % The amount of chains. % Random starting points. x = rand(P,1) * 120 - 60; % The size of the box. y = rand(1,P) * 120 - 60; for p = 1:P xt = x(p); yt = y(p); for n = 1:N xt(n+1) = xt(n) + sind(rand * 360); % Growth angle. yt(n+1) = yt(n) + sind(rand * 360); end % Change the transperance of chains to show 2.5D effect. plot(xt, yt, 'Color', [0, 0, 0, rand]) hold on end % Image properties. xlim([-50 50]) ylim([-50 50]) xticks() yticks() axis square;
By simple modification, a stretched network could also be produced.
